I have a Cisco AS5300 and is currently authenticating calls originating from ISDN and then passes the calls to VoIP.
Now I would like that the same application to authenticate the ISDN calls will be used to authenticate SIP calls directed to the 5300 and then pass the call to another SIP Server. I managed to get the application ansering the SIP call, but when I entered the destination number, the Cisco fails to route the call to another VoIP server.
I am getting the error “can’t gateway with peer tag”, were the peers are the same for the ISDN to VoIP setup.
Do you know if it possible for this setup to work.
