and at the night they do call tranfer towards a mobile phone.
I have two voice gateway. One works with H323 and the other works with MGCP. Calls coming on H323 and it goes out through MGCP voice gtw.
H323 doesn't support call tranfer, so I configured MTP on H323 gtw and I switch on MTP on H323 gtw configuration on CallManager. After that, call tranfer works, but call forward doesn't work toward PSTN numbers. Call forward works toward numbers on remote location.
The phones on remote location are on different region on Call Manager, then voice gateways.
When I don't have MTP on H323 gtw, I can do call forward towards PSTN numbers, but there is no call tranfer.
