Cisco AS5400 SIP Trunk source port ?

Hello,

Is there a command to fix the trunk signaling source port to 5060 in the Cisco AS5400XM ?

Thanks,

hi,

what's the exact issue?

IOS  can use random port as source port on SIP request.

However if you are running 12.3 then you cannot set it to one port.

Later 12.4(5a) and 12.4(6)T have following hidden command.

(config-sip-ua)#connection-reuse

This command sets used source port to SIP listen port.

It sets it to udp port 5060

Hope this helps!!

Thanks,

karthik

Hi Karthik,

If I use 12.3, How to change it without upgrade iOS?

Thanks,

Hi, you can try to use the command 'listen-port' but was introduced in IOS version 12.4.
