We have a large Cisco Call Manager VOIP Network. We do not use Cisco Routers so the IP SLA functions of VNQM are not applicable. However, I think the others functions such as monitoring 1 Publisher and 2 Subscribers along with the 80 or so voice gateways would be a benefit. Also having access to the CDR from the Cisco Call Manger should help with troubleshooting. We have over 2000 registered phones so not sure this is robust enough to monitor all of them at the same time. I would be interested in hearing how someone with a similar Cisco VOIP deployment this size uses VNQM. Thanks in advance.
