[Asterisk-Users] X100P keeping PSTN line Offhook

[Shahid]

Happens quite often. X100P FXO card puts the PSTN line offhook, so that no
calls go out or come in. The outside callers get a busy siganl while inside
callers cant dial PSTN.
Its a DELL optiplex P3 128MB ram 500MHz processor.

Here is some more info: (see the zapata.conf in the end)
Please direct me where to look for problem.
Thanks!!!
