Here's a great article to get your 
started:
Don't worry if your capture gets your more than just the 
RTP traffic, unless you're moving Mbps over that wireless link.  
Wireshark's RTP stream analysis will automagically select just the RTP streams 
to analyze.

What is jitter? And, is there anything around that might help me 
configure for capturing only RTP (if I understand correctly, the VoIP protocols 
ride on top of RTP which rides on top of IP?) and making sense of what's going 
on?

  Yes 
  Wireshark includes RTP stream analysis including latency and 
  jitter.

  Hi all,
I hope I can use wireshark for this task I 
  have.
There's two way voice traffic going on and at one point the IP is 
  sent across radios. The problem is that at some point, the sound comes through 
  delayed, though it always comes through complete. It sounds as if theres 
  buffereing taking place and the voice just stops, then continues. I'm thinking 
  maybe it would be something like one radio is not transmitting strong enough 
  which means some packet ACKnowledgements might not be making it back to the 
  voip source on the TCP network, but I need to see what the packet conversation 
  actually looks like to figure this out. 
I was hoping wireshark might 
  be a good tool here to help me troubleshoot what's going on.
Any help, 
  suggestions, comments on what to look for would be greatly appreciated since I 
  haven't yet done 
  this.
Will
