Re: RTP traffic monitoring

In case you need it for VoIP monitoring, there is a nice feature inside of IOS itself - Cisco IP SLA.

Re: RTP traffic monitoring

I have VoIP infrastructure with Asterisk servers and not with Cisco devices (only border routers and switches are cisco). And I need a monitoring tool like MRTG or something like this taht can do monitoring and create graphs.

Re: RTP traffic monitoring

Hi,

Every probe they sale today supports RTP. However there is some limitations in what kind of signalling protocol they support and that the traffic need to pass the probe.

It could be that the setup of the call will pass the probes interface but not the call itself because it is send directly between the phones. a good example is that teh call server is connected to the core switch as is the probe. Now on one acess switch you have two phones that make the call between them. Than de setup of the call will pass the probe but not the remainer of the session. (However this is usually not a problem since there would be a lowdealy and jitter on the very short path.)

If one of the phones call a phone not beeing on the same switch and the switch path or the routing path is through the core switch the entier call is seen.
