TTY on Southern Linc’s new CriticalLinc LTE Network

As Southern Linc’s network evolves to LTE, it also transitions from a legacy system to an Internet Protocol (IP) based system. Devices on Southern Linc’s LTE system that make Voice over LTE (VoLTE) calls will not be compatible with TTY. This includes TTY calls to 911 emergency services. If you have a communications disability and need to call 911 while using IP based calling over VoLTE or Wi-Fi, we recommend that you use an alternative means of communicating utilizing IP-based Telecommunications Relay Services (TRS) such as IP Relay or Video Relay Services (VRS). Additionally, you may send a text message to 911 directly, where text-to-911 is available. For more information please visit our Enhanced 911 and AGPS website.
