Please look at the c=IN IP4 section, (connection information), for the
good equipment your are telling us to send audio to <a href="http://203.206.181.174">203.206.181.174</a>
while on the bad equipment you are telling us to send audio to
<a href="http://81.201.82.39">81.201.82.39</a> which RTP is not supported. Please make the appropriate
changes on your side. Thank you.<br><br><br></span>-- <br>OnScreen and Voice Learning and Assessment<br><a href="http://www.learnosity.com">www.learnosity.com</a><br><br>
