Dear Sir,

I've connected 4 x FXO ports on the Hipath 3550 and I'am experiencing the well known FXO supervision problem. When a call is placed from the PBX side it is properly routed and establised but when the user hungs-up the phone  the call remains up on all relevant involved call legs.

I have tried all possible configurations on the Voice GW that is recommended by CISCO with no luck.

Could you please advice?

Hardware Configuration:

Cisco Voice GW:
Cisco 2821 - IOS 12.4(22) YB4
FXO Card: VIC2-4FXO (installed on NM-HD-1V Voice Network Module}

Siemens HiPath 3550

Did the same work for siemens hi path or any other vendor ? I talked to the vendor two days ago and he told me that, hi path pbx does not send any disconnect tone (so i cannot deduce the frequency and cadence values) however only a message with "Disconnect" is sent.
