CUCM 11.5 SIP TRUNK using CUBE

[fourier.ross1]

Placing a call from one UCM 11.5 cluster to the next the call fails. The phone rings on the other end the call is dead. The setup..... CUCM 11.5 <SIP Trunk> CUBE<SIP Trunk> CUCM 11.5 using two 7965 (SCCP) on both ends.

Attached is the sdl trace, debug ccsip error and debug ccsip messages.

Any help is appreciated.

Can you ping 64.11 from 65.254 ?? Yes I can ping.

Attached is the config on the CUBE....

Ok. Pass. Just check that you are pinging from interface 302

i imaging you are learning about the x.64.x route from ospf.

Also, the call is negotiating to iLBC for the codec.  Make sure that codec is supported on both CUCM servers.  Better yet, remove iLBC as a choice and only allow g711/g729 unless you specifically need iLBC.

I've seen negotiations to iLBC cause some weird behavior, not sure why.
