color:#1F497D'>I’ve not yet migrated to RRD, routers2, etc. and so had to
come up with a hack for traditional MRTG running on Windows. My process
is very similar to Dan’s, in walking the SNMP tree and counting the
number of channels set to 4 (established). It gives me the number of
calls in progress for the entire gateway instead of per trunk, but it’s a
start. I’m running on Windows (with gnu grep & snmpwalk
installed). At any given moment, the results of the .BAT file match the
sum of the lines in use as reported by the Cisco RTMT.<o:p></o:p></span></p>

I see in the archives a few questions over the years about monitoring Cisco
VOIP for such things as active calls, trunks in use and other performance
stats. Not many (or any) answers really. I've searched through MIBs and OIDs
and really have come up empty. By chance is anyone here using MRTG and SNMP or
a script to monitor such things on a Cisco Call Manager or a router acting as a
voice gateway?<br>
<br>
TIA,<br>
