Here's what Lumen's exit means for your business

Your contract just became a countdown.

Lumen has confirmed it’s ending sales of its voice products to focus on its network business. Here’s what that means for you:

Why Momentum

Built on voice, backed by teams who've done this for decades

25+ years delivering business voice at national scale, and we’re fully committed to it. You’re in good company: a dedicated team, a proven partner network, and the capabilities to keep you talking.

Built so you never go dark

Carrier-grade infrastructure with multi-region redundancy and proactive monitoring.

Secure by design

SASE and SD-WAN network security built in, plus GCC High and E911 compliance.

A partner, not a ticket queue

24/7 US-based support that owns your issue until it’s fixed.

Your numbers, kept

White-glove porting validated before cutover, so your callers never know.

One platform, every channel

Cloud voice, SIP, POTS replacement, and calling inside Microsoft Teams.

Move on your timeline

Migrations planned and phased around your contract, not a scramble.

The Migration Program

From first call to fully switched, without the scramble

Every migration runs on a plan, not a panic. Here’s how we take the risk out of the move:

Frame

Know your deadline (week 1)

We audit your Lumen voice inventory, numbers, locations, and contract terms, then hand you a migration plan mapped to your actual end date. No more guessing how much runway you have. You'll know to the day.

Frame Copy

Design the destination

Cloud voice, SIP trunking, POTS replacement, or calling inside Microsoft Teams. We build the platform around how your business works now, not how it worked when your last contract was signed.

Frame Copy 2

Cut over without the cliff

Dedicated migration engineers port your numbers and run the new service side by side with the old before switching. Your callers never notice. Your team never scrambles. Your business never stops.

Frame Copy 3

Keep momentum after the move

Named support team, proactive monitoring, and regular reviews. The finish line of the migration is the starting line of a partnership built to keep you connected.

Modernize While You Move

Move your calling to where your team already works

A migration you didn’t choose is still a chance to modernize on your terms. Skip the lateral swap and bring calling into Microsoft Teams, where your people already work. Momentum is an approved Teams Phone operator offering Operator Connect, Hosted Direct Routing, and managed SBC deployments. Do it once, do it right, and come out of this on a modern platform that’s stronger than what you started with.

Microsoft Teams

Bring calling into Teams, and everything with it

Momentum is a Microsoft-certified partner for setup, support, and billing. Turn Teams into your full business phone system, then add the services your team runs on.

Operator Connect

Add Momentum calling to Teams in a few clicks, managed right in the admin center.

Teams Phone

Full enterprise calling inside Teams, with Direct Routing and managed SBCs available.

Teams SMS & Texting

Business texting from your Teams numbers, so conversations stay in one place.

Teams Fax

Send and receive fax digitally through Teams, no fax machine or extra line required.

Public Sector

When the phones are mission-critical, your provider can't be a maybe. It has to be all in

Public sector organizations stayed with incumbent carriers for one reason: certainty. The moment that incumbent stepped back from voice, the certainty went with it, and the phones your community counts on became someone else’s afterthought. Momentum puts the certainty back on a modern platform: proven carrier-grade infrastructure, full E911 compliance, and GCC High support for agencies with federal security requirements. Your constituents don’t care whose roadmap changed. They care that the phones work. So do we.

FAQ

Lumen voice migration questions

Do I have to wait until my Lumen contract expires to switch?
No, and you shouldn't. We'll review your agreement and build a plan around your terms. The strongest position is having your migration designed 6 to 12 months before contract end, so you cut over on your schedule instead of a deadline's.
What voice services can Momentum replace?
Business lines, PRI and analog services, SIP trunking, hosted PBX, POTS lines, and Teams-integrated calling. If Lumen delivered it, we have a modern equivalent ready.
We're a government organization. Can you meet our compliance requirements?
Yes. Momentum supports E911 compliance under Kari's Law and RAY BAUM's Act and offers GCC High deployments for organizations with federal security and data-handling requirements.
Can you migrate multiple locations at once?
Yes. Multi-site migrations get a dedicated project manager and a phased rollout plan so every location moves cleanly, on a schedule that fits your operations.
What does support look like after we migrate?
You get a named support team, proactive network monitoring, and regular reviews. One partner owns setup, support, and billing, so there's no finger-pointing when you need help.
 
Will I keep my phone numbers?
Yes. Porting is core to every migration. Our team manages the entire process and validates every number before cutover.
How long does a migration take?
It depends on your services and number of locations. We build a schedule around your contract and run a phased rollout with a dedicated project manager, which is exactly why starting early beats starting under pressure.
Will there be any downtime during the cutover?
No. We run the new service in parallel with your existing lines and switch traffic over only once everything is validated. Your callers never hit a dead line.
Do you support Microsoft Teams calling?
Yes. Momentum is an approved Teams Phone operator offering Operator Connect, Hosted Direct Routing, and managed SBC deployments, so you can bring PSTN calling right into Teams.
How much does a migration cost?
Your assessment includes a complete plan with scope, schedule, and cost tailored to your services. There's no obligation, and in most cases modernizing lowers your total spend.

Your deadline is coming either way. Your continuity is a choice

One call gets you a no-obligation assessment of your Lumen voice services, your contract timeline, and a complete migration plan: scope, schedule, and cost. The deadline is already set. Whether your business meets it on your terms or someone else’s is entirely up to you.
