Hi all, I have a a production Elastix system with a Digium TDM410P (2xFXS, 2xFXO) card installed and working, but it seems the analogue lines/extensions spontaneously stop working after a seemingly random interval. Restarting the server brings it all up again. Shutting down Asterisk, restarting Zaptel and starting Asterisk again also fix the symptom. But at a random interval it will fall over again with no apparent cause. It's not all that critical, it's only used for a single cordless handset at present, but annoying all the same. Has anyone seen this before? I found a post on the Trixbox forum with the same fault, but no resolution and no other leads. Any help is appreciated. Dave.
