[asterisk-users] Disconnected Calls

[Ejay Hire]

Hello.

I am running asterisk 1.2.14 on a Dell poweredge with a Digium FXO/FXS card
connected to 6 analog lines and using Linksys spa942 phones.

My users are complaining of randomly disconnected calls, and when I watch
the log (debug warning,notice,error), I don't see any cause.  It looks like
asterisk is seeing a hangup from the analog end.

I have attached my zaptel.conf and zapata.conf.  What additional information
can I provide to make this an intelligent question?

Many Thanks,

Ejay Hire
