Having a slight issue, I have a BRI on a connected MGCP router that I need to have running as an NT.
It works fine when I add the command to the router;
Interface BRI 0/1/0
isdn protocol-emulate network
The problem comes when CM overwrites the BRI interface config and removes this line. I have found the offending line within CM as "Protocol Side" however I am only able to select User where I need to get this to change to network so it does not overwrite when MGCP gets the latest config.
Any ideas would be gratefully appreciated.
MGCP BRI operation is only currently supported for user side. This is documented here -
Choose the appropriate protocol side. This setting specifies whether the gateway connects to a Central Office/Network device or to a User device.
Note BRI supports only the User side.
If you network side operation, you will have to use H323. Refer here for additional details on configuring BRI voice cards for network side operation -
