I think it might be because it support ECS - Empty Capabilities Set, just a guess, which means without ECS a MTP resource has to be available. Check you CCM trace files for MTP when it's not working.

Subject: IPIPGW Question
Hi All
I tried to configure IPIPGW (CUBE) for my testing. When phone A (Zone Local
A) dial phone B (Zone Remote B), I hear ringback on phone A when phone B pick up the call. After checking, I need to uncheck the box " Wait for Far End H.245 Terminal Capability" under trunk configuration in CUCM.
I would like to know why I need to uncheck this box for IPIPGW (CUBE). Does IPIPGW does not suppot H.245? Can anyone provide some link for this issue.
Thanks
Best Regards
David
