Dear All
I have problem with configuring sip trunk on cube, my scenario is like below:
ITSP(SBC)>---------<(PBX) CUBE (sip trunk)>----------<ISSABEL>-----------IP SIP Phone
└-PRI[E1]>------------< Panasonic analog pbx
I can call from ip phone to panasonic and vice versa through my CUBE (CISCO2901) and everything is OK in two way
but when i call from outside to my ip phone (for example call 34567300 from 87654321) my sip phone ring and display caller id (87654321) correctly but caller can't hear anything even ringing (ringback) tone and when i pickup (off-hook) destination phone (ringing sip phone) , I can't hear anything and call disconnect after timeout (after 19 second)
I test the sbc by removing CUBE and connect my issable server direct to ITSP modem and i can send and receive call normally with this scenario so i think problem is in my CUBE
I spoke to ITSP and they told me they didn't receive any sip message from my router (but i see this 100 trying,180 ringing and 200 OK in my debug ccsip message output so i think problem is SIP message doesn't deliver correctly to SBC)
I even test without this lines but same result:
rel1xx disable
voice-class sip bind control source-interface GigabitEthernet0/1
voice-class sip bind media source-interface GigabitEthernet0/1
I have attached Debug output attached (debug voip ccapi inout & debug ccsip message)
My configuration on CUBE is:
my PBX ip is: 2.3.4.5 (ITSP gave this to me)
ITSP Gateway ip is: 2.3.4.6
ITSP SBC ip is: 5.6.7.8
my phone number is: 34567xxx
calling number for testing is: 87654321
