[cisco-voip] Monitoring concurrent calls on a WAN link?

[Lelio Fulgenzi]

I was thinking more along the lines of flows that fall within your voice IP address range. That should give you an idea of something that's going on.

We have some NetFlow tools, that are quite nice for a lot of stuff (including QoS marked traffic analysis and such) but (at least our tool) does not seem to offer anything telephony specific (such as identifying individual calls, concurrent calls etc.)

I know that NetFlow is a tool that is typically used for stuff like this. NetFlow is/was a licensed feature in IOS. There are a few free NetFlow readers out there too.

Hi, 



We have a central CUCM cluster and a number of remote sites. Is there a tool that could efficiently monitor over-the WAN calls? 



We’re interested in seeing per site concurrent calls, bandwidth used and such. 



I know RTMT is capable if showing some of these, but I have only found graphs aggregated by server and have found no way to filter out individual device pools or locations or anything. If I missed something obvious please do tell J
