To all the Cisco gurus,
I'm having troubles with configuration a Cisco 3600 to work with SER. If my
network (SER+Cisco) is running under port 5060, I can land calls as well as
have calls passed from PSTN to SIP. (Not perfectly, some refining is needed)
But my headaches starts when I switch the default 5060 port to some other port
(let's say 5080) due to some network restrictions, thus I must change from port
5060 to something else.
The problem I'm having is the following....
In Cisco 3600, I've setup session target to server-ip+5080.... but when SER
receives a call coming from Cisco, SIP messages (such as trying) will be sent
back to cisco via port 5060. I'm guessing this problem is caused by transport
listen port is default to 5060. If so, how do I change this to other ports???
Better yet, does anyone know how I can configure a cisco to run on different
ports under SIP??? I may be wrong with the transport and such, thus any inputs
or suggestions is welcome (and desperately needed)!! :>
Here?s a capture from my ngrep?.
