I have a 2800 gateway configured for the moment with one outgoing/incoming E1.
The configuration is a dial-peer pointing to a voice port. My voice-port is configured as follow :
voice-port 0/0/0:15
translate calling 10
cptone FR
bearer-cap Speech
I will add another E1 for the same dial-peer. As it's not possible to add two voice port for a dial-peer I tried to create a trunk-group under the voice-port but I have the following error :
C2821CCM(config-voiceport)#trunk-group 1
Error: Failed to add non-analog port to trunk group
Configure in cas-custom mode or serial interface
mode for T1/E1 digital ports and in BRI interface
mode for BRI voice ports
Creating the trunk-group under Interface serial prevent me to use the confiugration under the voice port (especialy cptone FR)
What is the best practice for trunk-group and how could i creat a trunk of voice-port ?
Thanks in advance
