[Dowling, Steve]

Tony, 

You can find the link to the CISCO MIBS here:  
<http://tools.cisco.com/ITDIT/MIBS/servlet/index>  

As a first cut, I'd recommend grabbing all the snmpv1 mibs relevant to
your IOS and hardware.  You'll find what CISCO make available to you
from this lot.  

You may find that the total voice traffic can be resolved to octets
in/out of a physical port.  Total number of active calls?  Shudder!
That ought to be in the CISCO MIB.

... and for Walid,  
I don't have cisco gear at this site, it's mainly Siemens stuff, so my
expertise is purely academic here.  I don't log jitter as the Siemens
does not report it.

We have Cisco 2851, 3845, and 3825 voice gateways.
Forgive me, I don't even know what is able to be graphed
or measured on them.  Maybe voice traffic and active calls would be a
good place to start? -tony
