I am having an intermittent problem i think with zaptel drivers with them becoming what i can only describe as unresponsive.
I am running asterisk 1.4 on Fedora 7 as a fax to email server (using rxFax)
Ocassionly (currently every 2 or 3 weeks) all calls into the asterisk box are instantly dropped, the zaptel drivers still appear to be running and when running zttool It shows that both the E1’s going into the box are fine.
Up until a couple of months ago we also had a lot of voice traffic going through the box, this caused the problem to occur more regularly(once or twice a week)
Restarting asterisk has no effect, the only way to fix it is to modprobe zaptel and wct4xxp.
Does anyone have any idea what could be causing this and if not is there any information i can gather when this next occurs which might help track the problem down?
