Hi all, I need help in disconnect supervision. Im running on AAH ver.2.5 at home with TDM400P with 1 FXO and 1 FXS (TDM11B). I have implemented DISA on AAH for origination (PSTN to VOIP bridging). I'm facing problems with disconnection supervision. My calls are not getting disconnected at times and it causes a lot of loss as the provider is charging me. After some serious study i have found that my provider (unusual in other part of the world) is not having a busy tone on disconnection and rather a long tone. (i.e - no ON and OFF). Hence the digium card is not able to identify the disconnection. I have also found out that the tone is having frequency of 425 and its Continous for around 10 seconds after i hangup. Does anybody has a fix for this in the configs so it will help my asterisk identify my hangup. Without this im not able to proceed. Thanks in advance. Dan
