FXO to FXO scenario

I am stuck with the following scenario:

PBX ---FXO ---A:1750 --PPP-- B:1750 --FXO --PBX

Whenever site A dials B (or vice versa) the call is not disconnected even if B answers and hangs up.

I tried in vain all the solutions form Cisco concerning this matter (ground start signaling – Power denial – Supervisory disconnect – Battery reversal) and unfortunately I cannot use any E&M or FXS ports.

May a have the basic configuration of this FXO/FXO scenario (to make sure that I don’t have any configuration errors) and a possible way to resolve the disconnect problem?

thanks

Re: FXO to FXO scenario

Refer to the following document:

http://www.cisco.com/warp/public/788/signalling/fxo_disconnect.html

Make sure you implement them correctly, i.e. to use groud

start signalling, you need to have this type of signalling configured on

both sides and also need to connect a jumper on the fxo card itself.
