Thank you, this is all helpful.
I just have one question. If I don't know the exact protocol that this
particular VoIP software is using, is it safe to say it will be riding on RTP and is there a specific way I need to
setup a filter to figure this out? Or how might I go about this?

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?

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
