Easing the IP transition

The introduction of AT&T Business Voice is part of a broader effort by AT&T to address the transition of business customers away from legacy TDM-based services, while not stranding existing equipment and other services that businesses use every day.

AT&T Business Voice offers a future-ready alternative by converting analog signals to Internet Protocol (IP) and has been approved by the FCC as a replacement product for businesses that have used traditional copper-based landlines

The service also allows business customers to retain their existing phone number and handset equipment, with support for essential lines such as fax machines, fire alarm panels, security alarms, elevator phones, and public safety phones.

Additionally, AT&T Business Voice is compatible with all types of transport and enables businesses to select between shared or dedicated internet connections, tailored to meet their specific needs.

Earlier this year, the FCC approved a version of AT&T Business Voice, previously known as AT&T Phone for Business – Advanced. AT&T Phone for Business – Advanced is a cloud-based solution that converts traditional analog landline signals to Internet Protocol (IP), delivering Voice over IP (VoIP) internet connections.

The AT&T Business Voice service leverages cloud capabilities from RingCentral and analog-to-digital converters from DataRemote. It can also use the AT&T wireless network if needed.

AT&T’s move is also about enhancing next-gen service revenues inside its Business Wireline segment.

Like the efforts AT&T has made in the consumer segment, AT&T is aiming to increase revenues from its newer IP-based services in the Wireline Business segment.

During the first quarter, AT&T Business Wireline revenues declined approximately 9% year-over-year, primarily due to continued pressure on legacy and other transitional services, which decreased by 17.4%. However, the decline was partially offset by growth in fiber and advanced connectivity services, which grew 4.5%.

Pascal Desroches, CFO and EVP of AT&T, told investors during its first quarter earnings call that the declines were “partially offset by growth in fiber and advanced connectivity services, which grew 4.5%” and that nearly “one-third of these revenues are from value-added services, which are variable every quarter.”

Two-part copper retirement plan

AT&T’s new IP-based service transitions for business customers also indicate the service provider’s ongoing move to retire its copper network.

The company plans to retire its legacy copper landline network by the end of 2029, with a two-phased approach. 

In areas where fiber is not being deployed, AT&T will transition customers to AT&T Phone Advanced, fixed wireless, or satellite services during the first phase. The second phase will concentrate on areas with fiber deployment, moving customers to fiber-based services. 

AT&T said this transition is driven by the high cost of maintaining the copper network and the desire to offer faster, more reliable services to customers. 

John Stankey, CEO of AT&T, told investors during the company's fourth quarter earnings call that it initially plans to retire copper in 1,300 central offices.

In December 2024, the company received approval from the Federal Communications Commission (FCC) to begin the process of discontinuing legacy voice services at these facilities.

“This was an important first step to establish a template that supports a deliberate and planned transition to a more capable and modern communications infrastructure,” he said.
