Continuant is headquartered in Tacoma, so when we talk about the Lumen voice end of sale for Washington, we’re talking about our own backyard. You’ve likely seen the headlines about Lumen Technologies exiting the voice business. The Lumen umbrella also includes Qwest and CenturyLink, so if either name is on your invoice, here’s what changed, what didn’t, and what the Lumen voice service transition means for your organization.
As of August 1, 2026, Lumen stopped selling and renewing voice services, including Qwest voice services for Washington and CenturyLink voice. Your service keeps running and stays supported, and no shutoff date has been announced. The date that matters is your own Qwest contract expiration or CenturyLink voice contract end, because that’s when service typically converts to month-to-month.
Your phone service was not shut off, and it isn’t scheduled to be. Lumen hasn’t published an end-of-life date for existing voice contracts, and current customers continue to be fully supported today. After the Lumen voice end of sale for Washington, existing lines keep operating and receiving support.
As of August 1, 2026, Lumen stopped selling and renewing voice services, and its partners can no longer write new voice contracts or renew existing ones. The affected products are SIP trunks, Voice Complete, Microsoft Teams voice services, and Zoom voice services sold through Lumen. For accounts under CenturyLink names, this is the CenturyLink voice end of sale.
Lumen has described the move as a shift in investment toward network-as-a-service and connectivity built for AI workloads, and away from legacy voice. Existing contracts are being honored throughout the Lumen voice service transition.

When your current voice contract reaches the end of its term, there’s nothing to renew into, and service typically converts to month-to-month. That’s what a CenturyLink voice contract end or Qwest contract expiration looks like under Lumen’s current approach. Month-to-month isn’t a crisis, but pricing tends to be less favorable than a negotiated contract, and you lose the predictability of a fixed term. The practical question isn’t whether your phone is about to stop working. It’s when your current term actually ends.
Depending on when your contract was signed and which product you bought, your paperwork may show Qwest Corporation, CenturyLink QC, CenturyLink Communications LLC, or Level 3 Communications LLC. All of these can be part of the same Lumen relationship, including legacy Qwest voice services for Washington. If any of those names appear on an invoice or master service agreement, this change applies to you. Our Is my voice contract affected? check walks through it.
In Washington, local exchange carrier service is overseen by the Washington Utilities and Transportation Commission. The WUTC doesn’t dictate a company’s product roadmap, but it’s a legitimate place to understand your rights during a carrier transition, alongside your own contract terms.
Higher education. A university or community college with emergency phones, fire panels, and elevator lines on analog circuits needs those mapped before anything moves.
None of these situations are emergencies, but all of them are worth a real look sooner rather than later, because the Lumen voice service transition reaches each organization at its own Qwest or CenturyLink term end.
No new orders or renewals. Existing service keeps running under its current terms.
No discontinuation date has been announced.
Service and Lumen support continue through your term. At term end, service typically moves to month-to-month.
Yes. Current Lumen, CenturyLink, and Qwest customers remain fully supported.
SIP trunking through a different carrier (see our PRI to SIP migration guide), a cloud platform like Microsoft Teams Phone, or a broader move off copper and TDM (see our POTS line replacement guide).
We’ve spent decades keeping enterprise voice and communications systems running for organizations across Washington, often on platforms the original manufacturer had stopped supporting. A carrier transition like this one is close to our daily work.
We start by reading your actual paperwork. Who your contract is with, which products it covers, and the true end date.
We map what you’d lose if nothing changed. Phone numbers, SIP trunks, fax lines, and anything tied to fire alarm or elevator circuits.
We lay out real options. SIP trunking with a new carrier, Microsoft Teams Phone or another cloud platform, or a paced retirement of old copper and TDM equipment.
Send us your contract or just your questions. No charge, no obligation. We’ll help you plan your Lumen voice service transition on your own timeline. For the national picture, see our Lumen voice end of sale guide.
