Key takeaways:
- Lumen doesn’t see voice in their future. They have announced the end of sale of their enterprise voice offerings. You need to start looking for a new carrier before your contract ends.
- Lumen’s exit is a symptom of a legacy infrastructure problem that runs deeper than one carrier. Networks built through acquisitions can’t sustain the economics of the AI era. Your next carrier could be strapping their technical debt to your stack.
- Your next carrier should be one that values your voice business. Lumen’s President, Christopher Davis Stansbury, said the quiet part out loud in their Q2 earnings call, “There’s very few customers that we actually need to be concerned about when we look at the bulk of that business.”
One of the largest carriers in North America announced it’s done selling enterprise voice.[1] On July 1, 2026, Lumen Technologies appeared to tell its channel partners it would stop compensating its industry partners for new voice sales.[2] By August 1, Lumen made it official that there would be no new SIP trunking, Voice Complete, PRI, toll-free, or hosted voice contracts.[3] Lumen operates under a seemingly endless number of names and brands after years and years of acquisitions, including Level 3, CenturyLink, Qwest, US West, or Embarq—which are all powered by their legacy voice businesses and subject to this change.[3]
Whether you’re an active Lumen voice user or not, this marks a critical turn the voice industry is taking and indicates how your voice vendor capabilities should evolve as well.
The situation is more time-sensitive than it looks, and the organizations that understand it now will have more options than those who find out at renewal.
What Lumen decided, and why
CEO Kate Johnson, who joined Lumen in 2022 from Microsoft, has spent the past several years rebuilding the C-suite and narrowing focus. The direction is clear: AI-era networking and Network-as-a-Service (NaaS). “We are positioning the company for long-term growth by concentrating our investment and go-to-market focus on modern digital network services,” Lumen stated in its July communication to partners.[2]
Lumen’s roadmap seems to mark a complete shift to AI-era networking while jettisoning its long-standing multicarrier voice business. Lumen grew through decades of acquisitions that created a patchwork network. After years of work with only a partially unified voice network, they have decided to completely redirect that capital toward AI infrastructure and data centers. The ongoing maintenance and support fees of a disjointed network don’t lend well to resolving over $13Bn of long-term debt.
The challenge with a network built through acquisition is that its history reflects in its operation: voice infrastructure assembled across multiple carriers and multiple generations of technology doesn’t modernize cleanly. Carriers who assemble their networks through acquisitions often still use legacy switches that add hops, complicate troubleshooting, and can affect call quality without tying back to a clear cause.
So even if your prospective carrier claims > 99.99% uptime, the quality of delivery would be degraded if they don’t own the full path from the calling party to your application server.
Carriers that built their networks as IP-forward and modern from the ground up, rather than inheriting a patchwork of acquired infrastructure and working backward to modernize it, are in a fundamentally different position to deliver on what enterprise voice requires today. Every enterprise using voice should take note and every Lumen customer needs a plan.
Turns out, investing in both AI and voice is possible
The right question isn’t just who can handle your voice today, it’s who’s building it with tomorrow in mind. Bandwidth is actively expanding global PSTN coverage for breadth and depth of voice offerings, investing in caller authentication and outbound trust services to secure your calls, and has dedicated teams to explore the next generation of AI in communications. Enterprises strengthening their voice and Voice AI, such as Wyndham and Genesys have shown their trust in this roadmap.
What “End of sale, not end of life” likely means in the real world
Lumen has stated that this is an end-of-sale announcement, not an end-of-life one. They drew that line explicitly on its Q2 2026 earnings call: existing contracts will run to term, and Lumen has committed to honoring those obligations.
Let’s break down what end-of-sale likely means in practice for current customers:
- Even though existing contracts will be honored until term end, once the contract expires, you could automatically shift into month-to-month terms rather than long-term renewals.
- Once you’re month-to-month, you lose negotiating leverage. Your pricing will be less predictable, with no locked-in terms, and no runway to plan a migration on your own schedule.
- Your critical communications will soon be integrated into a product with an uncertain future.
But there’s a risk that’s bigger still and might catch you by surprise: You may not get a renewal notice at all and miss out on any semblance of planning your carrier migration. When a service is at the end of sale, the normal renewal workflow often gets disrupted. If you’re used to Lumen reaching out before your contract lapses, don’t necessarily count on it this time.
Lumen also cut roughly 90 people from its Global Partner Solutions unit, including national channel managers and partner success managers.[5] The team that was actively managing enterprise voice relationships is largely gone. If you’ve been relying on your Lumen rep to flag contract timelines or flag issues, that relationship has changed.
Now is the time to start planning your migration away from Lumen before it’s too late. But if you want your plan to be future-proof, step back and see the bigger trend of transitioning away from legacy infrastructure to all-IP.
Lumen’s exit is the symptom, legacy infrastructure is the disease
Lumen’s exit is the most recent milestone in the migrations away from legacy ILEC voice infrastructure that have been occurring for more than a decade but is now gathering real speed.
Lumen’s CEO, Kate Johnson, noted in the Lumen Q2 Earnings Call, “We have a huge number of customers that have a very small monthly MRR, right, and do not have other services. And then we have a much smaller base of customers numerically, like a lower number that actually have a very large book of business with Lumen. And so we’re rooting our strategy in the larger footprint of revenue for obvious reasons, and we’re intersecting that with our strategy to exit copper.” [5]
The major carriers are all moving toward all-IP networks. The economics no longer support maintaining old equipment alongside modern AI investments, and that pressure is on the rise. The industry’s IP transition is a fact, not a forecast anymore.
How to find a Lumen alternative?
Start with an assessment of your current services.
Before you talk to a provider, know what you have:
Which services you’re running on Lumen: And CenturyLink, Qwest, US West, or Embarq. Don’t forget to include any you’ve inherited from acquisitions or could be missed running in the background. SIP trunking, PRI, POTS lines, toll-free, and hosted voice integrations with Microsoft Teams or Zoom are all in scope.
When your contract(s) expire: The accounts expiring in the next six to twelve months need immediate attention. Anything beyond that gives you more runway, but you’re better off knowing the full picture now than discovering a problem at renewal.
What your services connect to:Number inventories, contact centers, Microsoft Teams voice integrations, and 911 routing all have dependencies that take time to untangle. A voice migration that involves any of those needs more planning time, not less.
What are your modernization options: Start researching and evaluating your Lumen alternatives before you’re under deadline pressure. Evaluating UCaaS platforms, SIP trunking alternatives, and contact center connectivity is a different conversation when you have six months than when you have six weeks.
This baseline gives you a solid starting point. Without it, you’re guessing at timelines and scope, which usually means underestimating both.
What to look for in a Lumen alternative?
When done right, your carrier migration is an invisible change to your end users. To make it as friction-free as possible, a few carrier evaluation criteria matter most:
Look for direct PSTN connectivity or PSTN infrastructure ownership: If a provider is reselling capacity from an upstream carrier, they’re likely facing the same risk and migration challenge you’re facing now. On the other hand, a provider that owns and operates a network engineered with modern voice infrastructure is best equipped to back up their SLAs.
Carrier-grade reliability is non-negotiable: Customer experience doesn’t tolerate outages in main lines, toll-free, 911, and contact center connectivity. The infrastructure should have redundancies built in, aiming for at least 99.99% uptime. Make sure these redundancies aren’t added on as an upgrade tier.
Platform flexibility is critical for interoperability: Whether you run Microsoft Teams Direct Routing, Webex Calling, Zoom Phone, or a legacy PBX, your voice provider should deliver reliable voice without holding your platform choice hostage. If your stack evolves, your carrier shouldn’t be the thing that slows it down.
Think carefully about the migration, not just the product: Service provider migrations need hands-on project management with number porting, cutover coordination, 911 compliance, contact center continuity. First, look for a provider who reduces the risks in carrier migration. Lay out in detail who owns the outcome when something gets complicated.
A provider that treats voice as a core business: Does this provider treat voice as a core business? Ask directly: Is voice a strategic investment area for this provider, or a legacy service they’re tapering off? Lumen’s President, Christopher Davis Stansbury, said the quiet part out loud in their Q2 earnings call, “There’s very few customers that we actually need to be concerned about when we look at the bulk of that business.”
Indications of voice deprioritization become apparent in earnings calls, recent product releases, their support model, and their network investment roadmap.

Frequently Asked Questions
Not yet. Lumen announced an end of sale for their enterprise voice offerings, but has not released any information on the end of life for those products. This is ultimately driven by their “enhanced focus on higher-return digital products,” with voice excluded in their investments into the Lumen Programmable Network.[1]
Lumen has advised that existing voice services will be supported through the life of the contract. Upon contract completion, it is likely that it converts to costly month-to-month terms. We recommend that you confirm these details directly with Lumen.
Migration timelines are dependent on the intricacies of your tech stack. A standard voice migration using an existing PBX could be weeks, while complex muli-platform migrations could take months to a year. Either way, right now is your best time to start planning your migration. The Bandwidth team can discuss what your specific path forward looks like.
Your existing phone numbers can be transferred to a new carrier through the standard number portability process. The porting timeline for a standard migration is typically 2–4 weeks for local numbers and 4–6 weeks for toll-free. Numbers associated with 911 registrations or emergency routing require additional coordination and compliance verification, so factor that into your migration plan. Bandwidth’s porting team manages the process directly and coordinates cutover timing to minimize service disruption.
It is likely that you only need to replace your SIP provider, depending on the services you are using with Lumen. With the right carrier, you should be able to use your existing systems. Bandwidth prioritizes flexibility and compatibility, with a vendor-agnostic platform that allows customers to choose and integrate with their preferred providers, with Bandwidth as the carrier. Bandwidth offers the most direct-to-carrier integrations across UCaaS, CCaaS, conversational AI, and voice authentication tools. Whether you are running on-prem equipment, fully in the cloud, or a hybrid of both, Bandwidth more than likely has you covered.
Any prospective carrier should be able to share their service coverage before you commit. Bandwidth operates in ~70 countries and has National Operator status in 31 countries. If your enterprise has international operations, confirm your carrier’s actual country coverage for PSTN replacement, not just their ability to route international calls through a US gateway.
