[asterisk-users] Phantom calls: Detecting hangup quicker

[Gavin Henry]

Dear all,

We seem to be getting phantom calls when a inbound caller via the
legacy pbx hangups before
the SIP handsets have answered. The extensions also seem to hear
ringing on the lines too sometimes.

                                       SIP Inbound  >----
                                                               |
legacy pbx (analogue) <-> (sangoma a400d) asterisk <-> SIP phones

Basically if a user hangups before the call has bridged, I think.

Is there anything we can do about this?

Thanks,

Gavin.
