Hi
some users are facing issues with connecting a call. when they dial using cipc the cucm routes them via sip trunk for which i have attached one packet analysis and logs below. the caller says that the call rings and then he gets fast busy tone. the call reciever also complains of so.
10.65.102.11 is CUCM pub
10.65.12.3 is Router
