[Asterisk-Users] Need to track dropped calls

[Carl Youngblood]

We use IAX for PSTN connectivity.  Our phones are Linksys SPA-942s
running SIP.  We are connecting to our voip provider over the UTOPIA
municipal network in SLC.  Our network connectivity has been great
until about two weeks ago, when we started to experience 5-10% packet
loss due to a router malfunction or something.  The packet loss seems
to have gone away, but I just want to make sure that I am attacking
these problems from all angles.  I just wanted to know if there was
some way I could examine the asterisk logs to see if any calls
terminated abnormally.  I wanted to put this into our monitoring
system so that I could track these issues better.
