<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">He reports they’ll be on a phone call to Jamaica (or other World Zone 1 / International destination).<u></u><u></u></p>
<p class="MsoNormal">The called party will end the call… and he’ll report hearing the last 15-30’ish seconds of the conversation “looped”.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">It almost sounds like someone’s maybe doing TCP on the RTP, and something screwy going on with the packetization.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Anyone else heard of this or have a theory?<u></u><u></u></p>
