Still same problem, I have erased all that related to mgcp on my router, to start from scratch
2811(config)#controller T1 0/2/0
2811(config-controller)#pri-group timeslots 1-24 service mgcp
Cannot overwrite no serv type with one. Unconfigure existing configuration and reconfigure
2811(config-controller)#
Where is this error coming from ??
Here is what I want to try:
192.168.15.10  - pub
192.168.15.11 - sub
controller T1 0/2/0
pri-group timeslots 1-24 service mgcp
