Microsoft Teams Phone vs Outright Vanity Numbers: BYO Path

26 min read

Microsoft Teams Phone is the rare cloud PBX that does not pretend to be number broker. It is the calling layer attached to the most-installed productivity stack on the planet, and the architecture is openly built on the assumption that the actual phone numbers come from somewhere else — your existing carrier through Direct Routing, a Microsoft-vetted partner through Operator Connect, or a Microsoft Calling Plan if you want one bill. None of those paths optimize for premium vanity selection. None of them try to. Teams Phone is the cleanest enterprise UCaaS for layering an outright-owned vanity number onto, because the platform was designed BYO from the inside. The other comparison posts on this site lean honest. This one barely needs to. The vendor architecture already agrees with us.

Ninety-second decision tree for any Microsoft 365 shop weighing Teams Phone against a brand-bearing inbound line. Numbered, in order:

  1. Is Microsoft 365 already the productivity backbone — Outlook, SharePoint, Teams, OneDrive, Entra ID — for every employee on day one? Then Teams Phone earns serious consideration. Same client, same identity, same admin center, same Copilot surface. Switching cost for a non-Microsoft PBX inside an M365-native shop is the new tab employees never open.
  2. Does the digit-string on signage, vehicle wrap, business card, billboard, podcast outro, or website footer need to live as a recall asset for the next 10 to 25 years? Buy it outright from Digit Exclusive. From $200–$250 one-time. Microsoft does not sell premium vanity inventory in any of its three calling models — that is by design, not by oversight.
  3. Are both true at once — Microsoft 365 is the operating system AND the inbound number is brand-bearing? Buy the vanity outright, then port it into your Direct-Routing carrier (AT&T, Verizon, Lumen, BT, Tata, Bandwidth, Intermedia, etc.) or your Operator Connect partner. Microsoft handles UC and Copilot. You own the asset. This is the textbook enterprise pattern under FCC Local Number Portability rules (47 CFR Part 52).
  4. Already nine months into a Microsoft Calling Plan with an assigned-pool number nobody remembers? Buy a vanity outright, port it into the Calling Plan tenant or migrate to Operator Connect / Direct Routing with the new vanity as the primary DID. Auto-attendant, call queues, voicemail, and Copilot transcription stay configured.
  5. Trying to pick a winner between Teams Phone and outright vanity? Stop. They are different layers. Teams Phone is the call-control and Copilot surface inside Microsoft 365. The vanity number is the regulated telephone number on the common-carrier network. The grown-up answer for any M365-native shop with a public-facing line is both, with the carrier slotted into the middle.

The rest of this article expands the checklist — the three Microsoft calling models in plain English, the Direct Routing wedge that makes BYO-number cleaner inside Teams than inside any competing PBX, the four-column comparison, the cost math at 1, 5, and 25 years, the seven-step port-in walkthrough, and the questions M365 enterprise architects actually ask during licensing renewal. We sell premium vanity numbers From $200–$250, paid once, owned forever. Microsoft publishes Teams Phone Standard at roughly $8 per user per month, Teams Phone with Calling Plan at roughly $15 per user per month, and Direct Routing as BYO-carrier at variable carrier rates. Two different products. Two different jobs. Almost always combined inside Microsoft 365 enterprises.

Why Microsoft Teams Phone Is the Cleanest BYO-Number Fit in UCaaS

Every other comparison on this site has the same shape: the competing UCaaS vendor wants to sell you the seat AND assign you number from its upstream carrier pool, and the article exists to explain why those two purchases should be unbundled. Microsoft Teams Phone is the one platform where the architecture itself unbundles them. Direct Routing was published as a first-class deployment model in 2018 and the documentation has always assumed customers would bring their own SIP trunk and their own DIDs. Operator Connect added a curated marketplace of Microsoft-vetted carriers in 2021 — same BYO premise, easier procurement. Microsoft Calling Plan exists for shops that want one bill, but Microsoft has never positioned it as the sophisticated path. The platform tells you, in writing, that the number is supposed to come from somewhere else.

That is why the wedge is structural rather than rhetorical. Teams Phone earns the seat because Microsoft 365 already owns the desktop. The number on the door earns its own purchase order because the digits have to outlive the next licensing cycle.

The three Microsoft calling models, in plain English

Teams Phone Standard is the call-control add-on at roughly $8 per user per month. It enables enterprise voice features inside Teams — auto-attendant, call queues, music on hold, voicemail, call park, group call pickup, shared line appearance — but provides zero PSTN connectivity by itself. You attach connectivity through one of the other two models. This is what most M365 E3 shops actually buy.

Teams Phone with Calling Plan is Teams Phone Standard plus Microsoft acting as the licensed PSTN carrier in supported countries, at roughly $15 per user per month including a per-user minute bundle. Microsoft assigns the DID from its carrier inventory; vanity selection inside the admin center is small and generic. One bill, simple onboarding, fine for distributed sales teams that need a US number and do not care about the digits.

Direct Routing is Teams Phone Standard plus a customer-supplied SIP trunk to a customer-chosen carrier. The carrier owns the PSTN side, Microsoft owns the Teams side, the SBC (Session Border Controller — typically AudioCodes, Ribbon, Oracle, or Anynode) handles the handshake. AT&T, Verizon, Lumen, BT, Tata, Bandwidth, Intermedia, Sangoma, NUSO, and dozens of regional CLECs are common Direct Routing carriers. The number you bring in — including a vanity number purchased outright from a broker — sits on that carrier's network and routes into Teams.

Operator Connect sits between Calling Plan and Direct Routing. Microsoft maintains a curated marketplace of carriers (AT&T, Verizon Business, Bandwidth, BT, Lumen, Telia, Singtel, Rogers, BT Wholesale, Tata, etc.) who have built native integrations into Teams admin. You contract with the carrier directly, but Microsoft handles the technical integration. No SBC to manage. Simpler than Direct Routing, more flexible than Calling Plan, BYO-number-friendly by design.

Where Teams Phone is honestly mid-pack

Teams Phone is not the deepest contact center — for high-seat inbound queues with skills-based routing and supervisor whisper, Genesys, NICE CXone, Five9, and Talkdesk lead, with Teams Contact Center and Microsoft Dynamics 365 Customer Service in the chasing pack. Teams Phone is not the most innovative pure-play UCaaS — Dialpad's real-time AI sales coaching is a tier above Copilot for raw coaching mechanics, and 8x8's XCaaS contact-center-and-UC unification is broader. Teams Phone is not the lowest-cost PBX — Phone.com, Ooma Office, and Grasshopper are cheaper at the bottom end. Teams Phone wins where Microsoft 365 already won, which is most of the Fortune 2000 plus a long tail of mid-market and SMB shops on Microsoft 365 Business Standard or Premium. That is enough.

Four-Column Comparison: Teams Phone, Outright Vanity, Hybrid, Mobile

Honest comparison adds the consumer-mobile path most "Teams Phone vs vanity" articles skip. Many solo professionals, founders, and small partnerships inside the Microsoft 365 universe do not need the Teams Phone PBX layer at all — a memorable owned number on a Verizon, AT&T, T-Mobile, Mint Mobile, or Google Voice SIM does the entire job, and Teams calling can ride personal mobile via the Teams mobile app where useful.

Dimension Teams Phone subscription only Outright vanity (Digit Exclusive only, on consumer SIM) Hybrid: Outright + port via Direct Routing or Operator Connect Consumer mobile only
Setup cost $0 upfront. Add-on billed per seat. From $200–$250 one-time From $200–$250 once + carrier port-in (often included in carrier setup) Carrier activation only
Year-1 cost (10 seats, Teams Phone Standard + Direct Routing carrier) ~$960 Teams + ~$1,200 carrier = ~$2,160 $250-$600 paid once $250-$600 once + ~$2,160 / year (Teams + carrier) Carrier plan only
5-year cost (10 seats) ~$10,800+ Teams + carrier (assume flat; expect 4-7% annual escalation) $250-$600 total ~$11,000-$11,400, but the digits remain yours forever Assigned-pool number is forgettable
25-year cost (career-length brand line) ~$54,000+ if Teams + carrier pricing held flat (it will not) $250-$600 total Subscriptions recur; the recall asset never resets 4-6 carrier numbers churned in 25 years; brand recall reset every time
Number ownership at end of contract Calling Plan: returns to Microsoft pool. Operator Connect / Direct Routing: number lives on carrier you contract with — portable. Yours, on a regulated common carrier of your choice Yours, portable to any US carrier or PBX Carrier owns it; portable but rarely memorable
Premium vanity selection Calling Plan admin: small, generic, extra fee. Operator Connect / Direct Routing: depends entirely on carrier inventory — usually small. 15,593 unique premium patterns across area codes Same as outright; routes through Teams Phone Carrier random-assigns; vanity rare
Microsoft 365 + Copilot integration Yes — native, included in licensing tier N/A — no PBX layer Yes — native, on the owned number None
Best fit M365-native shops not yet at signage / billboard scale Solo, creator, 1-to-3-person partnership Any M365-native shop with a brand-bearing inbound line Personal use, internal-only lines

Five-year math is the row most renewals hinge on. A 10-seat Teams Phone deployment via Direct Routing — $8/seat/month for Teams Phone Standard plus a typical $10/seat/month for the SIP-trunk carrier — runs roughly $10,800 over five years before factoring 4 to 7 percent annual telecom-vendor escalation. Adding a $250 to $600 outright vanity from our 15,593-number inventory is a rounding error against that subscription stream. The digits become a brand asset on the balance sheet, independent of which UCaaS suite Microsoft 365 evolves into by 2031.

Who Microsoft Teams Phone Actually Wins For

The real Teams Phone buyer profile is structural, narrow inside its addressable market, and very wide in absolute terms because Microsoft 365 covers most of the addressable enterprise:

Microsoft 365-native enterprises, 50 to 50,000 seats, Outlook-Teams-SharePoint culture

Financial services, legal, manufacturing, federal contractors, healthcare systems, K-12 and higher ed, professional services, energy, retail head offices — anywhere Microsoft 365 was the procurement default ten years ago and the workforce is fluent in the Teams client. Replacing the PBX with one outside Microsoft 365 adds a tab employees do not open and a second SSO surface IT does not want to maintain. Teams Phone wins because it does not require behavior change.

Direct Routing buyers with an existing telecom relationship

Mid-market and enterprise shops with a multi-year master agreement with AT&T, Verizon, Lumen, or a regional carrier already negotiated favorable per-minute rates and SLAs. Direct Routing keeps that contract intact and layers Teams call control on top. Procurement loves it. The carrier loves it (the SIP trunk revenue stays). The CIO loves it (no rip-and-replace). And the brand-bearing vanity number sits on the carrier side, exactly where it lives best.

Operator Connect buyers who want simplicity without lock-in

Mid-sized shops who do not have the SBC engineering bench for Direct Routing and do not want the Calling Plan single-vendor lock-in. Operator Connect is the middle path — a Microsoft-vetted carrier ports your number, manages PSTN, and integrates natively into Teams admin. No SBC to procure, license, monitor, and patch. Most BYO benefits, less operational overhead.

Copilot-forward organizations standardizing on one AI surface

Shops that have rolled out Copilot for Microsoft 365 and want the same AI surface across Outlook drafts, Teams meeting recap, and now Teams Phone call summary. One Responsible AI policy, one Entra ID identity, one purview compliance perimeter, one Copilot data boundary. Different from running Microsoft Copilot, Zoom AI Companion, and Google Gemini for Workspace as three separate AI vendors.

Federal, state, K-12, and healthcare buyers

Microsoft 365 Government (GCC, GCC High, DoD) and Microsoft 365 Education ship purpose-built compliance overlays for FedRAMP, IL-2, IL-4, IL-5, FERPA, HIPAA, and CJIS-relevant configurations. Teams Phone inherits those compliance boundaries. For buyers who already passed Microsoft through a security review, attaching Teams Phone keeps the compliance surface inside one vendor with one BAA.

Where the buyer profile breaks

If the binding constraint is high-seat contact center with skills-based routing, supervisor whisper, and workforce management at scale, Microsoft Dynamics 365 Contact Center is credible but Genesys, NICE CXone, Five9, and Talkdesk are deeper — see RingCentral vs outright for an adjacent UCaaS-plus-CC view. If the constraint is real-time AI sales coaching with talk-time-ratio and filler-word feedback inside the live call, see Dialpad vs outright. If the constraint is Zoom-native culture instead of Microsoft-native, see Zoom Phone vs outright. If the constraint is bottom-end pricing for 1-to-5-person shops with no Microsoft 365 culture, see Grasshopper vs outright or Phone.com vs outright.

Why Teams Phone Reps Do Not Try to Sell You the Number

This is the section where every other comparison post on this site has to do real work. Here, Microsoft does the work for us. Teams Phone field sellers are trained to lead with Direct Routing or Operator Connect for any account that asks about number portability, vanity selection, regional carrier preferences, or telecom-vendor consolidation. The platform documentation states plainly that Calling Plan is the optional path and Direct Routing is the more flexible default for sophisticated buyers. The number — on Direct Routing or Operator Connect — sits on the carrier you choose, owned by the subscriber-of-record relationship between your organization and that carrier, fully portable under FCC LNP. Teams Phone is the call-control layer riding on top.

What that means for a brand-bearing line: buy the vanity outright from a broker, ask your Direct Routing carrier or Operator Connect partner to port it in, route inbound through the SBC or Operator Connect peering, configure auto-attendant and call queue inside Teams admin, and let Copilot summarize the calls. The asset is yours. The PBX is Microsoft's. The carrier is the one your CFO already negotiated with. Three vendors, three layers, zero conflict.

Premium-vanity inventory does not live inside Microsoft Calling Plan, Operator Connect partners, or most Direct Routing carrier pools — repeating-digit (8888, 7777, 5555), AABB and ABAB layouts, ascending sequences, palindromes, and word-spell patterns require a purpose-built broker. 15,593 unique premium numbers across all 50 states and DC, sold as one-time outright purchases starting From $200–$250.

The Hybrid Path: Outright Vanity Ported Into Teams Phone

The hybrid pattern is the architecturally cleanest outcome inside Microsoft 365 — supported by the platform, documented inside the Microsoft Learn portal, and what most M365-native shops with brand-bearing inbound lines converge on. Seven-step walkthrough:

  1. Pick the vanity from Digit Exclusive's 15,593-number inventory, filtering by state, area code, pattern type, and budget. Most premium inventory sits between $250 and $1,500. One-time checkout.
  2. Receive carrier-of-record activation from the seller-side carrier. You become subscriber-of-record on a regulated common carrier. The number is yours immediately, before any porting decision.
  3. Pick your Teams Phone connectivity model. Direct Routing if you have an existing carrier MSA and SBC engineering bench. Operator Connect if you want a Microsoft-vetted carrier with native integration. Skip Calling Plan for vanity work — Microsoft is not the right carrier for a digit-string you intend to keep for 25 years.
  4. Initiate inbound port at the destination carrier. AT&T Direct Routing, Verizon Business, Lumen, Bandwidth, BT, Tata, Intermedia, Sangoma, or any of the dozens of supported carriers. Sign LOA, supply seller-side carrier verification, send recent bill copy. Standard FOC date is 5 to 10 business days for US local numbers.
  5. Provision in Teams admin. Microsoft Teams admin center → Voice → Phone numbers. The ported number appears under the carrier's pool. Assign to user, resource account, auto-attendant, or call queue. Configure caller ID, voicemail, call routing.
  6. Configure Copilot for Teams Phone on the eligible licensing tier. Call summary, action item extraction, follow-up email drafting, and CRM integration with Dynamics 365 or Salesforce. The Copilot surface sits on top of the owned number, not inside the carrier.
  7. Document the architecture in your Microsoft 365 admin runbook. The number, the carrier, the LOA, the SBC config (if Direct Routing), the Operator Connect contract (if applicable), the Teams admin assignment. If you ever change carriers, the number ports out under FCC LNP and follows you. If you ever leave Microsoft 365 entirely, the number ports out and follows you. The asset is decoupled from every renewal cycle, forever.

The walkthrough takes roughly 2 to 4 weeks end-to-end for a typical mid-market deployment, dominated by carrier port-in lead time rather than Teams admin work. For multi-site enterprises with hundreds of DIDs across multiple carriers, the project is bigger but the per-number mechanics are identical.

Cost Math: 1, 5, and 25 Years for a 10-Seat M365 Shop

The framing renewals actually run on. Three time horizons:

Year 1. Teams Phone Standard at $8/seat/month for 10 seats = $960. Direct Routing carrier at $10/seat/month = $1,200. Total ~$2,160. Add a $250-$600 outright vanity once. Total Year 1: ~$2,360-$2,760. Of that, $250-$600 is permanent and ~$2,160 is recurring.

Year 5. Teams + carrier at flat pricing = $10,800. With realistic 4-7% annual escalation = $11,800-$12,400. Owned vanity = same $250-$600. The recall asset has not appreciated and has not depreciated; it has done its job for five years for free.

Year 25 (career-length brand line). Teams + carrier at flat pricing = $54,000. With escalation = $80,000-$130,000+. Owned vanity = same $250-$600. The number on the truck wrap, billboard, business card, and podcast outro has compounded brand recall for 25 years and cost nothing after the original purchase. Subscriptions are an operating cost; owned digits are an asset.

This is the lease-vs-purchase decision in its most honest form. Lease the PBX from Microsoft and your Direct Routing carrier — the call-control software, the AI surface, the carrier-grade SLA, the regulatory compliance overlay all justify the recurring spend. Purchase the digits outright from Digit Exclusive — the recall asset has nothing to gain from recurring spend and everything to lose from vendor lock.

Microsoft Teams Phone vs Adjacent Comparisons

For M365-native architects evaluating Teams Phone alongside other UCaaS options, the adjacent comparisons on this site cover the realistic alternatives:

None of these vendors compete with us on the number itself. All of them support inbound porting under 47 CFR Part 52 LNP rules. The structural answer for any shop with a brand-bearing line is the same regardless of which PBX you pick: buy the digits outright, port them into whichever UCaaS layer earns the seat.

If your communications stack is Cisco-centered instead, compare Cisco Webex Calling vs buying a vanity phone number outright before you decide where number ownership should live.

FAQ: Microsoft Teams Phone and Outright Vanity

Does Microsoft Teams Phone sell vanity phone numbers?

Not directly. Microsoft Teams Phone is the call-control add-on inside Microsoft 365 ($8/user/month for Standard). The actual phone number comes from one of three connectivity paths: Microsoft Calling Plan (Microsoft is the carrier, $15/user/month bundled), Operator Connect (a Microsoft-vetted carrier you contract with), or Direct Routing (a carrier you choose, BYO SIP trunk). Vanity selection inside any of those paths is small and generic. For repeating-digit, AABB, ABAB, ascending-sequence, palindrome, or word-spell premium patterns, go to a broker like Digit Exclusive and port the number into your Direct Routing carrier or Operator Connect partner.

Can I port a vanity number I bought outright into Microsoft Teams Phone?

Yes. Inbound porting is supported by every Microsoft Teams Phone connectivity model under FCC Local Number Portability rules (47 CFR Part 52). Buy the vanity outright from Digit Exclusive, sign the Letter of Authorization with your Direct Routing carrier or Operator Connect partner (or with Microsoft directly for Calling Plan), provide seller-side carrier verification and a recent bill, and the port completes in 5 to 10 business days for standard US local numbers. The new number appears in Teams admin under the carrier's pool and is assignable to users, resource accounts, auto-attendants, and call queues.

What is the difference between Microsoft Calling Plan, Operator Connect, and Direct Routing?

Calling Plan: Microsoft is the licensed carrier in supported countries; one bill from Microsoft for both Teams and PSTN; simple onboarding; vanity selection limited to Microsoft's carrier pool. Operator Connect: you contract directly with a Microsoft-vetted carrier (AT&T, Verizon Business, Bandwidth, BT, Lumen, Telia, Tata, Singtel, etc.), they handle PSTN, Microsoft handles native integration; no SBC to manage. Direct Routing: you bring your own SIP trunk from any carrier, you operate or co-manage an SBC (AudioCodes, Ribbon, Oracle, Anynode), maximum flexibility and best fit for existing telecom relationships. For a brand-bearing vanity number, Operator Connect or Direct Routing is the right path; Calling Plan is fine for assigned-pool DIDs that do not need to be memorable.

How much does Microsoft Teams Phone actually cost in 2026?

Microsoft publishes Teams Phone Standard at roughly $8 per user per month as a Microsoft 365 add-on. Teams Phone with Calling Plan runs roughly $15 per user per month including a per-user minute bundle in supported countries. Operator Connect costs the operator's published rate (commonly $5-$15 per user per month for the PSTN side) plus the $8 Teams Phone Standard license. Direct Routing costs whatever the SIP-trunk carrier charges (often $5-$15 per seat per month or per-channel pricing for high-volume) plus the $8 Teams Phone Standard license, plus SBC licensing and operations. A 10-seat Teams Phone Standard + Direct Routing deployment runs roughly $1,800-$2,700 per year. Verify current pricing on Microsoft's licensing page; UCaaS pricing pages move quarterly.

Can I port my number out of Microsoft Teams Phone if I leave?

Yes. Microsoft and every supported Operator Connect partner and Direct Routing carrier honor port-out requests under FCC LNP regulations. The receiving carrier or PBX initiates the port, you sign the LOA, the losing carrier releases the number on the FOC date. If you bought the vanity outright before porting in, the number was already legally yours; the port-out simply moves the routing. If you used Microsoft Calling Plan and Microsoft assigned you number from its pool, you can still port that number out under LNP — but the number was assigned, not curated, so you may not have strong reason to keep it. Outright purchase is the structural answer for any digit-string you intend to keep regardless of which UCaaS vendor you use in 2031.

Does Microsoft Copilot work on Teams Phone calls?

Yes. Microsoft Copilot for Teams Phone provides call summary, action item extraction, follow-up email drafting in Outlook, and CRM updates in Dynamics 365 or Salesforce on eligible licensing tiers. Voicemail transcription and call analytics are bundled at lower tiers. Copilot for Microsoft 365 licensing applies; verify SKU eligibility. The Copilot surface rides on top of whichever number the call hit — including a vanity number ported in via Direct Routing or Operator Connect — so the AI productivity layer and the brand-bearing number are independent purchasing decisions.

Is Microsoft Teams Phone a good choice for my main published business phone number?

Teams Phone is an excellent choice for the call control, Copilot, auto-attendant, call queue, voicemail, and Microsoft 365 integration of your main published number. It is a less-good choice as the legal owner of the number itself, because Teams Phone is not number broker — Microsoft Calling Plan assigns from a pool, Operator Connect routes through partner carriers, and Direct Routing routes through your chosen carrier. The standard pattern: buy the number outright from Digit Exclusive, port it into your Direct Routing carrier or Operator Connect partner, and let Teams Phone handle UC and Copilot. The recall asset and the UCaaS layer end up with two different owners, which is exactly the architectural posture an M365-native enterprise wants.

Is Microsoft Teams Phone better than Zoom Phone, RingCentral, or 8x8?

Different wedges. Teams Phone wins for any organization standardized on Microsoft 365 — Outlook, SharePoint, Entra ID, Teams chat, Copilot — which is most of the Fortune 2000 and a long tail of mid-market and SMB shops on M365 Business Standard or Premium. Zoom Phone wins where Zoom Workplace is already the meeting and chat surface. RingCentral wins on broad UCaaS depth with international and contact-center reach. 8x8 wins on XCaaS unification of UC and contact center. None of them sells premium vanity inventory at depth; all of them support inbound porting from outright brokers. Pick the PBX whose wedge matches your binding constraint. Buy the digits outright regardless.

Does Microsoft Teams Phone Calling Plan offer toll-free numbers?

Yes. Microsoft offers toll-free numbers as part of Calling Plan in supported countries, with separate per-minute rates for inbound. Operator Connect partners and Direct Routing carriers also offer toll-free where applicable. Digit Exclusive does not — our inventory is local-area-code only across all 50 states and DC. If you specifically need a toll-free line, work with your Calling Plan, Operator Connect, or Direct Routing provider. Our wedge is local-area-code premium vanity recall, owned outright, no subscription.

Can a solo professional or 1-to-3-person partnership skip Teams Phone entirely?

Yes. Outright vanity numbers ship portable to any standard US carrier — Verizon, AT&T, T-Mobile, Mint Mobile, US Cellular, Google Voice, Google Fi. Many solo Microsoft 365 Business Basic subscribers run a memorable owned number directly on a personal SIM with no PBX layer at all and use Teams Calling integration through the Teams mobile app where useful. The Teams Phone PBX layer is required only for multi-seat extension fan-out, auto-attendant, call queue, shared line appearance, or Copilot phone-call summary. Below that complexity threshold, the owned number on a personal carrier is the cleaner stack.

What is the cleanest enterprise architecture for an M365-native shop?

Buy the vanity outright from Digit Exclusive (From $200–$250, paid once). Port it into your existing Direct Routing carrier (AT&T, Verizon, Lumen, Bandwidth, etc.) or your Operator Connect partner using LOA-and-carrier-verification under FCC LNP. Provision the number in Teams admin. Configure auto-attendant, call queue, voicemail, and Copilot. Pay Microsoft roughly $8 per seat per month for Teams Phone Standard and your carrier roughly $5-$15 per seat per month for the SIP trunk. Own the digits forever. If you ever leave Microsoft 365, the number ports out and follows you. If you ever change carriers, the number ports out and follows you. Three vendors, three layers, zero asset risk.
