FXO and disconnect problem

[mflak]

When I connect FXO i Cisco 2611XM (12.3) to PSTN and used "supervisory disconnect anytone" is impossible to make the call from FXS to PSTN.

Why?

Any body know?

I need this command because this solve problem with no call disconnection when call goes from PSTN with no answer from my side (Phone still ringing). I found that "supervisory disconnect anytone" work correctly but any other "supervisory disconnect ..." commands not.

Any suggestions?

Hello.

You must turn on debugs and look does FXO try made a

call or not, next you must connect analog telephone

tube between cisco and PSTN and hear on what stage you

receive disconnect ( I suppose when PSTN generate

ringback tone )

And only after that possible give you recomend.
