That was on the machine with the TE410P.

I'm attaching the output of zttest (zttest.txt) and concurrently
running vmstat 1 (vmstat.txt). Please see if you can make something
out of it because I don't really know what the numbers mean.
Thanks,
Waldo

Hello guys,
I've been having a a recurring problem with people complaining
about calls being dropped.
I have 3 asterisk servers:
Gateway: running Asterisk 1.2rc2 with TE410P connected to 4 T1s
of the PSTN
Server 1: running Asterisk 1.2rc2 with ztdummy using Gateway to
access the PSTN (in/out)
Server 2: running Asterisk 1.0.9 with ztdummy using Gateway to
access the PSTN (in/out)
I have agents connected to both Server 1 and Server 2.
The problem is that every once in a while, agents complain that
their calls dropped. Sometimes it's some agents that complaint,
some other times, ALL agents complaint at the same time.
When these complaints occur, the only thing I so is:
1) Issue a show channels on all three servers to see if there are
any ongoing calls. I assume that if there are active calls, that
not all calls dropped
2) Issue dmesg in Gateway to see if any of the T1s presented an
alarm that could have dropped the calls
In either case, I don't see any errors in dmesg indicating there
were problems with the T1s and I always see active calls in all
the servers.
What can I do to further troubleshoot this? If I look at the CDR,
how can I tell that a call was "abnormally" terminated? Are there
any tools out there that would allow me to check the health
status of the working system and not just the "availability" of
the machines? I was looking at nagios but I don't know if it will
do what I need to do.
The other thing I could think of is that there may be a network
problem in the building. The way everything is connected is all
agents are connected to a series of unmanaged switches in the
"call center floor", which are daisy chained together and then
one is connected to the main switch with a single cable drop. The
main switch is where the Asterisk servers are connected. I
figured that if one of the switches in the call center area
fails, it could drop all calls or if there is a problem with the
cable drop from the main switch, that could also affect all
agents.
Any advise will be greatly appreciated.
Thanks,
Waldo
