In case you want to know the nitty gritty.<br><br>excerpt from switch_types.h<br><br>RTP_BUG_SONUS_SEND_INVALID_TIMESTAMP_2833 = (1 << 1)<br> /*<br> Sonus wrongly expects that, when sending a multi-packet 2833 DTMF event, The sender<br>
should increment the RTP timestamp in each packet when, in reality, the sender should<br> send the same exact timestamp and increment the duration field in the 2833 payload.<br> This allows a reconstruction of the duration if any of the packets are lost.<br>
<br> final_duration - initial_timestamp = total_samples<br><br> However, if the duration value exceeds the space allocated (16 bits), The sender should increment<br> the timestamp one unit and reset the duration to 0.<br>
<br> Always sending a duration of 0 with a new timestamp should be tolerated but is rarely intentional<br> and is mistakenly done by many devices.<br> The issue is that the Sonus expects everyone to do it this way instead of tolerating either way.<br>
Sonus will actually ignore every packet with the same timestamp before concluding if it's DTMF.<br><br> This flag will cause each packet to have a new timestamp.<br> */<br><br><br><br><div class="gmail_quote">

Thanks, I have and I was well aware of these (I've been lurking).<br>
<br>
However, my issue is with another platform and Sonus. I want to<br>
demonstrate that this is a *known* issue with Sonus gear. Plus, I<br>
found it:<br>

Thanks again!<br>
