First sorry for my English.
In FreePBX distro 1.810.210.57-1, and 1.811.210.57-1 there is a problem when using attended transfer.
First UserA call UserB.
Next UserB answered. UserA said the transfer of the UserC (UserB use *2 for this).
User C picks up the phone and tells the userB will not accept the call and hangs up.
In this case the call is cut off from the userA and userB.
in current version don’t work: A->B, B *2 to C, C answered B, but hangup after 5-10 seconds, B could’t tell A why C hangup…
in version 126.96.36.199-2 work: A->B, B *2 to C, C answered B, but hangup after 5-10 seconds. Channel between user A and B is up! UserB can tell UserA.
Sorry for my English.
