<div dir="ltr"><div>Hello Steve,</div>
<div> </div>
<div> I uderstand from paragraph 3.2 in RFC-2833 that the sender may send some audio of the DTMF while sending the events, until it revognises that this is a DTMF tone. The 60mSec is what I've been told by Vega engineers.</div>

</div></div>Are you saying the Vega sends 60ms of DTMF as audio, then sends RFC2833<br>DTMF packets and mutes the audio? In what reading of the RFC is that<br>considered appropriate action? In addition, a DTMF detector should<br>
detect is more like 40ms. 60ms is rather long.<br><font color="#888888"><br>Steve<br></font>
