Sounds like a possible disconnect issue, When the lines are not available
try doing a 'zap show channel X' with X being the channel number 1,2,or
3
and see if asterisk thinks the line is onhook or offhook. Just a thought.

Subject: [Asterisk-Users] All lines are busy
Hi all. I ma having a problem with pstn/tdm lines.
After the system has been in use for a while, it seems that I can only
use one line in the system. I have three PSTN attached to Digium
TDM04B/400P and they are grouped into g0. I tried using callprogress and
busydetect in the zapata.conf but then my SIP phones can't place calls
on hold anymore. (Thought that was pretty strange). Once I restart the
asterisk server and the zaptel service it works normally for a while and
then goes back. No matter what happens, one line is always available to
dial in or out on. Any suggestions would be most appreciated.
Thanks
CM
