AT&T POTS Line Discontinuation & Business Voice Replacement Options
AT&T is retiring legacy copper-based Business Access Lines, commonly called POTS lines, in many areas. Businesses still using traditional analog telephone service should identify those lines now and move critical applications to a modern replacement before legacy service is discontinued.
AT&T POTS Line Shutdown Timeline
| Group | Notification Sent | Service Discontinuation |
|---|---|---|
| D1 Wire Centers | June 2025 | June 30, 2026 |
| D2 Wire Centers | November 14, 2025 | November 15, 2026 |
Customers generally receive approximately 12 months after notification to migrate affected services before the scheduled discontinuation date.
AT&T Business Voice Can Replace Traditional POTS & Analog Lines
AT&T Business Voice is a cloud-based Voice over Internet Protocol solution that can modernize traditional POTS and analog telephone services while continuing to work with existing compatible analog equipment.
That makes it especially relevant for businesses that are not simply replacing an office desk phone, but have operational equipment that still depends on an analog telephone line.
AT&T Business Voice Features for Critical Lines
Up to 24 Hours of Battery Backup
Built-in battery-backup capability can help maintain Business Voice service during a power disruption, subject to operating and environmental conditions.
Optional Wireless Failover
Wireless failover can provide an additional connectivity path to help maintain service if the primary broadband connection is disrupted.
24/7 Remote Monitoring
Business-critical lines can be remotely monitored around the clock with automatic notifications to help improve visibility into service status.
Works With Existing Analog Equipment
Businesses may be able to modernize the underlying phone service without immediately replacing every compatible analog device connected to the line.
Self-Service Management
Business Voice includes tools for managing calling features and line capabilities through a self-service portal.
Scalable Business Service
Businesses can add or adjust lines and capabilities as their needs change rather than remaining dependent on legacy copper infrastructure.

Other AT&T POTS Replacement Options

- AT&T Phone for Business
- AT&T Business Voice
- AT&T Office@Hand
- IP Flexible Reach
Availability and suitability depend on the location, broadband availability, number of lines, connected equipment and business requirements.
Do Not Assume Every POTS Line Is Just a Telephone
Before disconnecting a legacy copper line, determine exactly what is attached to it. Businesses often discover POTS lines supporting equipment that employees rarely think about.
Voice
Traditional business phones, reception lines and other voice applications.
Fax
Fax machines or multifunction devices that still use an analog telephone connection.
Security
Alarm panels and related security applications that may rely on legacy telephone service.
Utility Applications
Other business-critical analog equipment that needs a compatible replacement path.
What Businesses Should Do Now
- Inventory every active POTS line. Identify the phone number, location and monthly cost.
- Determine what each line supports. Do not disconnect a line until you know what equipment is attached.
- Separate ordinary voice lines from utility lines. A desk phone and an alarm panel may require different replacement approaches.
- Review broadband availability. AT&T Business Voice requires broadband connectivity and electrical power.
- Select the proper replacement. Match the application to Business Voice, Phone for Business, Office@Hand or another appropriate solution.
- Install and test before disconnecting copper. Critical applications should be confirmed operational before the legacy line is removed.
