How do you troubleshoot Jitter & Latency?

Does anyone recommend a type of packet sniffer to determine jitter and or latency?

If a client complains about "silent" spaces and/or noise what is the best way to determine the cause?

Is there a "Cisco recommended" software or freeware?

Thank you.

Use Wireshark with SIP filtering and look for the BYE message to see endpoint to endpoint stats.

Ya know, the phones also have history of connections and I have seen this there too...

Hi Paul,

There is a command which for some reason I am unable to remember of the top of my head, that allows you to see this on the IOS per ephone I believe...

This is one method, to which was used frequently when I did an ISR 2800 deployment with 30 remote CIPC staff coming in on the system, but I suspect your question though is pertaining more to a SIP trunk and the users experience of that right?

Wireshark is good for this although you really have to wade through a truck load chatter and at times can be confusing.

As soon as I can remember or even find the command I will post it for you to check that one out as well.
