SIP

Archangel, 2012-09-19 08:41:31

A question to skilled tsiskovodam.
I came across an ASA5505, already configured by someone and working for a long time and successfully as a regular Internet distributor.
Now there was a problem with SIP-ohm. The problem itself is not so important.
During the proceedings, I came across the fact that the inspector for the SIP protocol does not work on the ASA. That is, I definitely see successful registration in the PBX settings (on SIPNet), make a call (it passes), and on ACE, show sip - shows “nothing” (that is, not even the usual Total: 0, but nothing at all, just an invitation for input). debug sip - also silent.

ciscoasa# show sip
ciscoasa# show service-policy | grep sip
Inspect: sip, packet 0, drop 0, reset-drop 0

I encountered ASA for the first time, it's not even clear where to dig.
