asterisk users - Jan 2007 - Disconnected Calls

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

I upgraded to the newest 1.2 Zaptel release and this is still occurring.  I
checked and the digium card is not sharing an IRQ with any other devices.

I also changed busycount=8, and set callprogress=no.

The call drops are still occurring.  Mid-conversation ` in 10 calls will be
disconnected.
Any other suggestions?

This is a relatively low volume system.  Usually running less than 1 or 2
concurrent calls.  Would turning on debugging logs to a file cause a
problem?

Many thanks,
Ejay Hire

Hi Ejay!

Why have you excluded possibility that the problem is on telco side?
