[asterisk-users] Dropped Calls on TDM400p

[Jonathan Barratt]

Thanks for the reply Steve.

I am calm now.  :)

I've been getting the exact time and number of the dropped calls for the
last couple weeks, and there was nothing in system or asterisk logs at those
times.  So I've spent the last three days sitting at the server, in their
office.  I can see nothing out of the ordinary going on when the calls are
dropped.  It seems to happen mostly on outbound calls.

The TDM400p is on the same interrupt as the graphics card but nothing else.
I didn't think this
would be an issue as the box was running headless.  So I guess first up is
changing PCI slots.

MB is an EPoX EP-8KTA2L.  I haven't yet found the Hardware Compatibility
List on digium.com to determine if it's supported or has known issues, but
will keep looking.

I was expecting issues, and we've had many of them (esp. echo), but I've
been able to resolve them all myself with research and experimentation,
except for this persistent intermittent dropped call problem...

I'm really grateful for your input Steve, please keep it coming!

Thanks very much!
Jonathan
