[Asterisk-Users] Asterisk hangup for no reason (FXO)

[Joel Duffield]

I am using asterisk as a voicemail for an old Nitsuko TIE ONYX VS system. it
sends the signals through DTMF, and that works ok sometimes. but when a call
comes in from outside and is transfered to voicemail or goes to voicemail
because no one picks up, the following happens.

the interface rings
asterisk picks up
waits for digits
then it just "hangup" for no reason.

Now comes the weird part if I split the line and just after asterisk picks
up, I pick up a phone that is on the same port, I hear the digits and
asterisk transfers to the right extension, and everything is good. What on
earth is going on here it is driving me crazy, I am using fxs_ks for the
signaling could this be doing it?

Please help
I am so out of ideas.
