CM with SIP

mattsthe2

So i started my new job today as a "All things Cisco Man".
They are running SIP on 4.2.

To my horror i have no experience with SIP.
Is there any good websites that any of you know to bring me up to speed?

Im so used to MGCP and things like debug isdn 931..

figured it out...

They are running a Call manager trunk to the provider and letting them deal with the SIP calls.

Still bummed though, i really like q931 for troubleshooting.
