Hi,
I assume you capture near the receiving end of the connection. That means
there's a cause in the transmitter and/or the link towards you.
Make a measurement near the transmitter and verify that it's timing is correct.
Then follow up all networking equipment in between.
Yes, it's a pain, but that's what you get moving from circuit switched to packet
switched networks.
Thanks,
Jaap

I am attempting to figure out why call quality is soo poor, I have got a
packet capture from our system with 2 calls in it. I am just not sure
exactly what I am looking at. Reading through what I could find on
google I think it looks like I am dealing with jitter due to latency. My
packet capture shows:
Max Delta: 1020 ms for both calls
Max Jitter: (between 91-97)
Mean Jitter: (between 39-41)
No lost packets.
So, I guess my question is how do I figure out why these values are so
high? Is there any thing else I should look at in wireshark to give me
an indicator as to what is going on?
Thanks, Joe
