SIP Calls cannot be estabilished

Hi Folks,

I'm trying to estabilish a Sip call, but the call cannot go through. I'm sending 3 invites and not receiving any ACK.

I have attached the debug ccsip all output.

CALL FLOW:

IP Communicator -> CUCM -> H.323 Gateway / CUBE -> SIP Provider -> External number

Why I cannot estabilish the call?
