How to connect Cisco IP-Phones to a 4G LTE Network?

[howkudyou]

Hello!

I would like to ask if anyone could tell me how I can use a Cisco 2911 with an EHWIC-4G-LTE-G to connect IP-Phones to a 4G Network? I want to be able to call my mobile phone from a Cisco IP-Phone connected to the callmanager on the 2911 Router.

I was only able to find configuration samples to use the 4G connection for normal data and not for Voice Traffic.

I hope someone can help me.

Kind regards

Can you please clarify if there is on your enviroment a CUCM Server or if the telephony is solely managed by a CUCMExpress ie, by the Voice Telephony Service on the Router?

If it is the second, then you will need to do some reading on CME Configuration examples:

Hope this helps,
