[cisco-voip] FXO discconnect problem

[Anthony Kouloglou]

  Hi Mohamed,
i have never manage to find a solid solution on this problem.
I guess only TAC can help.
They can guide you how to identify disconnect tones that your local 
Telephony Provider sends and then applied them using IOS commands
(like those you have added in the voice class dualtone-detect-params 1)
