I have third party H.323 GSM gateway which doesn't support transfer between two calls made through it. For example I'm dailing a mobile number then I want to transfer it to another mobile. The call drops and the vendor tell us that they doesn't support this functionality. The same thing happen when conference call is made and the initiator leaves the conference. The Gateway is registred directly into CallManager 4.1(3) as H.323. Gateway. Is it possible to realize middle point that can hold the call in this cases?
Thnaks in advance.
