Question about SIP traffic through Cisco 3640

[npereira]

Hi all,

I am trying to see if the traffic to/from port 5060 is passing through my router.

Is there any easy way to do this apart from port sniffing.

I need to see if my SIP RTP are going through the router.

If you don't have any traffic other than SIP/RTP you can do a "debug ip udp". This would show debugging like this.

Dec 13 14:47:49: UDP: sent src=xx.yy.163.70(5060), dst=192.168.2.45(5065), length=383

Dec 13 14:47:49: UDP: sent src=xx.yy.163.70(17063), dst=xx.yy.181.6(14565), length=56

Dec 13 14:47:49: UDP: rcvd src=xx.yy.181.6(14565), dst=xx.yy.163.70(17063), length=16

I'm not seing any traffic udp on port 5060 hitting the external interface using the "debug IP udp".

5060 is TCP though right? only RTP is UDP...?!?

So how could I see the SIP sessions on 5060 witting the router to confirm there getting at least there?
