Good morning to you all.I would like to ask you to some question about outgoing call fail via sip trunk.We have 2 BE7K and last week we setup direct SIP trunk from CUCM to ITSP. SIP Trunk from CUCM and ITSP's SIP Proxy is connected and service is up.When we make outgoing call,call is rejected.Could I get your support to solve this issue? Following is setup diagram.
Solved! Go to Solution.
I have collected the CCM logs for on test call.
called number : 90067718
calling number: 2222
start time : 11:00 am
end time : 11.02 am
call flow : 2222 extension call access code 6 follow by external phone number 90067718
issue : call setup fail.
i checked the logs and found 126.96.36.199 is replying with 403 forbidden message, for the invite message.
best is to check with the person managing 188.8.131.52 and understand why this is happening.
for your reference you can share the invite with "Call-ID: firstname.lastname@example.org" to them.
