[Asterisk-Users] Hangup Supervision Issue on Digium TDM11B

[sdcharly at gmail.com]

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
