Dear,
I have cucm 11.5
I have problem with configuring sip on cube, my scenario is like below:
ITSP---------CUBE----------CUCM-----------IP Phone
I have no incoming and outgoing call.
the problem is that when i call the sip number from PSTN or my cellphone. the ip phone ring and answer the phone but i haven't any ring back or voice from the ip phone. and the call disconnect after exactly 20 seconds.
as i see debug ccsip message it disconnect SIP 2.0 504 gateway timeout with cause=102.
I attach debug ccsip message and ccapi inout and cube configuration.
i configure the CUCM side with All default parameter(1.standar sip profile 2.non secure sip trunk security profile 3.MTP required is Checked 4.Correct MRGL 5.g711alaw 6.change min-se to 90 and sip session timer to 300)
i appreciate if someone could help me.
thanks
