Sending and receiving RTP audio

[Kapil Agrawal]

Mat,

I think this is related to the data being lost during transmission, as I
faced similar issue in one project.
I fixed that by configuring rtppay in such a way that mtu is fixed and of
some 1400 bytes.

Not sure if you have similar issue.

Best Luck
