Hello all,

I need a help with one issue.

I have this scenario:

IP phone A -> CUCM--> IPIPGW --> CUCME -> IP Phone B.

When I make a call from phone B to phone A, everything works fine. But when I make a call from phone A to phone B, I am not able to do any action thet needs MTP (Hold, Transfer....), no matter if I'm using g729 or g711. I have CUCM resources and transcoders on IPIP gw and one other gateway as a MTP.

How should I set up media resources? I have tried almost all possible combinations, but still nothing.

Thanks in advance.

Hi Kamil,

Which protocols are in use here?

If you're using all of one protocol, you shouldn't need MTP.



This is dependent on the version of the ipipgw. I would move to 20T or later for full functionality.
