We are using the CME 4.1 version in one site. When someone calls a cellular nummber a voip dial peer sends this call to a CME 3.2 in another site which has some connections with the cellular network.
The problem is that when the caller (in the CME 4.1) tries to transfer the call to another extension in the same CME 4.1 the call drops.
What causes this problem? How can we solve it? Would this problem be solved using H.450.2 between the two CMEs to handle the call transfer?
Thanks in advance for your help.
