If your organization runs voice service in Montana under a Qwest, CenturyLink, or CenturyTel contract, you may have seen news about Lumen Technologies stepping back from the voice business. Your phones are not being shut off, and nothing about your service changes today. But there is a real shift underway, the Lumen Voice End of Sale for Montana, and the state’s hospitals, clinics, and universities have good reason to understand it now rather than later. It affects any organization whose paperwork references Qwest voice services in Montana, CenturyLink voice, or another Lumen-branded Montana business phone service.
As of August 1, 2026, Lumen stopped writing new voice contracts and renewing existing ones, including CenturyLink voice and Qwest voice services in Montana. Existing service keeps running, and no shutdown date has been announced. When your term ends, service typically converts to month-to-month, so start by confirming the term end date for each service you buy.
As of August 1, 2026, Lumen stopped writing new voice contracts and stopped renewing existing ones. That covers SIP trunking, Voice Complete, PRI and POTS lines, toll-free service, and hosted voice for Microsoft Teams or Zoom sold through Lumen. It’s an end-of-sale decision, not an end-of-life announcement.
Lumen has been direct about redirecting investment toward networking and AI-driven connectivity rather than legacy voice and copper. On its Q2 2026 earnings call, the company’s CFO confirmed to investors that Lumen had “announced end of sale” for voice, with no shutdown date set for service already in place.
End of sale means Lumen won’t sell new instances of the affected products or renew expiring terms, while current service continues. Existing CenturyLink voice and Qwest voice services in Montana keep working unless you make a change that requires a new sale.

They already have: August 1, 2026. Since that date, you can’t buy new SIP trunking, Voice Complete, hospital PRI circuits, or additional lines on a Voice Complete contract from Lumen, and renewals for Montana business phone service under Lumen-branded entities aren’t offered.
Existing customers keep their current service working, and there’s no shutoff date for in-place services, whether that’s Qwest voice services in Montana or a CenturyLink voice arrangement. What changes is at the edges: you can’t renew terms, add features that require a new sale, or expand capacity under the same product.
The part worth planning around is term end. When your agreement reaches it, there’s no new contract to renew into, and service typically converts to month-to-month, which keeps working but usually costs more and carries fewer protections. For a Montana hospital or university, the real question isn’t whether phones stop working on some fixed date. It’s when your specific contract ends, and what you want lined up before then. That applies equally to a Voice Complete contract, SIP trunking, and hospital PRI circuits that support paging and life-safety systems.
Montana’s voice history runs through more than one corporate name. Depending on your location and when you signed, your paperwork might show Qwest Corporation, CenturyLink QC, CenturyLink Communications LLC, or CenturyTel of Montana, Inc. Qwest Corporation has historically served the state’s larger population centers, including Billings, Missoula, and Great Falls, while CenturyTel of Montana covers many smaller and more rural exchanges. Both are Lumen, and both are covered by the same end-of-sale decision. If any of these names appear on an invoice or service agreement, this applies to you. Our Is my voice contract affected? check walks through it.
In Montana, telecommunications carriers operate under the Montana Public Service Commission, which regulates local exchange telephone companies doing business in the state. The Commission has previously investigated legacy network issues, a sign of its attention to reliability. That context is worth knowing as you plan for the Lumen Voice End of Sale for Montana and review your Voice Complete contract language or CenturyLink voice terms.

Healthcare. For hospitals running a Montana business phone service on legacy circuits, replacing hospital PRI circuits with SIP trunking works well where life-safety requirements can be met, with paging, nurse call, and alarms tested before cutover.
Higher education. For universities, transitioning a university phone system away from legacy TDM is often overdue anyway. Mapping the university phone system to modern SIP trunking or a cloud platform is the common path, with cutovers timed around the academic calendar. A university phone system typically has the most hidden analog lines of any site we see.
Continuant has spent decades supporting hospitals, universities, and enterprises through voice transitions. We start with a no-cost environment review to identify your contracting entity, covered services, and true term end dates. Then we map what’s at stake, from phone numbers and SIP trunks to hospital PRI circuits, emergency call boxes, and university phone system elements, and present options aligned to the Lumen Voice End of Sale for Montana timeline: new-carrier SIP trunking, cloud migrations, or phased retirement of aging copper. We also handle number porting, configuration, E911 compliance, and training. For the national picture, see our Lumen voice end of sale guide.
