Router support VoLTE/VoNR feature will supply FXS port for VoLTE voice, in which users can make or receive phone calls over the 4G/5G network simply by connecting the router to their existing telephone set.

Explanation

For TP-Link Routers with VoLTE/VoNR support, the feature is enabled by default and cannot be disabled or configured. You only need to insert a SIM card into the router to use it. It should be noted that the VoLTE/VoNR feature only works when dialing via the SIM card. Once the router switches to the EWAN line, the feature will be disabled. If you want to support voice calls on the EWAN line, you need to enable VoIP.

QA

Q1: What is the difference between VoIP and VoLTE/VoNR?

A1:

• VoIP (Voice over Internet Protocol): VOIP technology allows voice calls to be made over the Internet rather than traditional telephone lines. The network type is Broadband internet, and the voice quality depends on the internet speed and bandwidth. VoIP offers a lower cost than traditional phone services.
• VoLTE/VoNR: As mention above, VoLTE/VoNR uses the same LTE/5G data network for both voice and data, providing a more seamless and integrated experience. Routers with VOLTE support can connect to the 4G/5G network and support VOLTE/VoNR- enabled voice calls.
