AT&T’s latest move aims to modernize traditional lines
According to AT&T, its all-in-one VoIP system supports a wide range of business lines, including fax machines, fire alarms, security systems, elevator phones, as well as public safety phones.
Businesses that want to modernize their copper-based services might find AT&T Business Voice a suitable solution. The carrier’s newly announced service converts analog signals to Internet Protocol (IP) and has been approved by the FCC (Federal Communications Commission) as a replacement product for businesses that have used traditional landlines.

- 24/7 Monitoring: Remote monitoring and automatic notifications to ensure reliability for business lines.
- Built-in Battery: Built-in battery backup for service during power outages.
- Wireless Backup: Optional automatic failover to a 4G LTE connection permits uninterrupted service during broadband interruptions.

- Enhanced Telephony Management: Modern calling features that can be customized for business needs such as 24/7 virtual receptionist, simultaneous ringing across multiple lines, customizable Caller ID, and centralized voicemail management.
It’s also worth mentioning that AT&T Business Voice is compatible with all types of transport and allows businesses to choose between shared or dedicated internet connections to meet their needs.

AT&T has also introduced two plans for those business customers that need Business Voice. The cheaper one costs $25/month and includes unlimited calling nationwide and to Canada, Mexico, and US territories, 40+ voice features, and unlimited international calling in 51 countries as low-cost add-on.
The expensive plan costs $60/month and converts traditional analog utility lines to digital connectivity. This plan supports devices other than phones, from faxes and call boxes to security and alarm systems. It also allows management using the same control panel as voice lines. This specific service replaces the traditional telephone service (POTS).
