Judge rules against AT&T in California COLR lawsuit: what dealers should do now

AT&T MASTER AGENT

California just won an important early round in a complex legal fight that could shape how “basic phone service” is delivered across the state. A federal judge denied AT&T’s request for a preliminary injunction—meaning California can keep enforcing its Carrier of Last Resort (COLR) rules while the lawsuit continues.

Quick refresher: what COLR rules require

COLR rules obligate designated providers (primarily AT&T in California) to deliver reliable basic voice service and access to emergency calling for customers who request it.

Here’s the key detail dealers should understand: California says its COLR framework is technology neutral. In other words, AT&T doesn’t necessarily have to keep using copper lines—basic service can be delivered via fiber, wireless, and/or VoIP as long as the state’s quality standards are met.

What the judge decided (and why it matters)

AT&T asked the court to temporarily stop California from enforcing COLR during the litigation. To win that request, AT&T had to show it was likely to succeed on the merits—specifically that California’s rules are preempted by an FCC order.

Judge Linda Lopez didn’t buy it. The court denied the preliminary injunction, so AT&T must continue following California’s COLR requirements while the case plays out. AT&T can appeal this ruling to the 9th Circuit, and it can also appeal later depending on how the underlying case ends.

AT&T’s position: “We’re spending $1B/year on a network almost nobody uses”

AT&T argues California is forcing it to maintain a century-old copper network at major cost—claiming it spends $1 billion per year to keep it running. The carrier also notes it has received relief from COLR obligations in 20 out of 21 states where it still offers wireline service (with California as the exception).

AT&T says only about 3% of its California customer base still uses copper lines for calls. The carrier’s broader goal is to retire copper, but critics argue AT&T wants to do that without fully replacing it with fiber in less profitable areas.

California’s position: “AT&T is allowed to use fiber, wireless, or VoIP—so stop acting like this is impossible”

California officials call AT&T’s legal strategy “a facade,” arguing the company is framing the issue as “analog vs. digital” to escape obligations. The state says AT&T can meet COLR requirements using modern alternatives (fiber/wireless/VoIP) and that the CPUC rules do not block those options.

Dealer playbook: how to turn this into practical customer solutions

1) Expect more “home phone” and “911 reliability” questions

This case brings basic voice service and emergency calling back into the spotlight—especially for seniors, rural customers, and small businesses that still depend on a traditional home phone line.

2) Build a simple migration menu (copper → fiber/VoIP/wireless)

Even if the lawsuit drags on, the direction of travel is clear: copper is shrinking. Dealers should be ready with three clear options:

• Fiber-based voice (where available): best for stability and long-term replacement.

• VoIP over broadband: good fit when the customer already has reliable internet.

• Wireless home phone: practical in areas where fiber isn’t economical—sell it with the right expectations and backup plan.

3) Sell “backup connectivity” as insurance (especially for wireless home phone)

If a customer is pushed toward wireless for home phone, your upsell is resilience: a backup internet option, a hotspot/router solution, and power protection so the customer can stay connected during outages.

4) Start a “June 1, 2027” readiness conversation with affected accounts

AT&T’s filings referenced stopping basic service for 184,000 residential and 15,000 business subscribers starting June 1, 2027. Whether or not that exact timeline holds, dealers should treat it as a planning trigger:

• Identify customers still relying on legacy landline setups

• Confirm broadband availability and reliability at the address

• Offer a migration plan before service changes become urgent

Bottom line: California “wins” this round because the state keeps enforcement power while the case continues. For dealers, the opportunity is to become the translator—turning legal headlines into a clear home-phone migration plan that protects reliability and keeps customers from feeling forced into a bad option.
