config guide helped to correct the incoming call translation rule, now incoming are working fine. But i have not able to make outbound calls.
Here a scenarion: i have 7821 phone dialling international number 0.00393450462650 it waits 3 sec and gives busy tone. strange thing is that i am not getting any debug on gateway to which sip trunk is pointed. i used below debug:
debug isdn q931 debug ccsip mess debug voip ccapi inout
Phone(78XX) ======= cucm ====== sip trunk (RP 0.!) ======= VG ======= BRI(0/2/0 and 0/2/1) line
the only sip message i am getting
SIP/2.0 483 Too Many Hops Via: SIP/2.0/UDP 10.105.244.145:5060;branch=z9hG4bK255405654adc39 From: <sip:10.105.244.145>;tag=2115088433 To: <sip:10.100.46.244>;tag=DA00384-FF Call-ID: email@example.com CSeq: 101 OPTIONS Reason: Q.850;cause=100 Content-Length: 0
i have attached the gateway config for your reference. Can you explain me the concept how the call flow should here in this scenario, what should be remember in this topology.
