<div class="">I have a endpoint that expects audio and
video over ports 5052 and 5054 respectively. I am
using the following script to send audio and video.
I am getting a '<span style="font-family: Menlo;

<div class="">Also, does using simple rtp payloads

does this hinder retransmission of rtp packets?</div>
