capture and listen to the audio it sounds like a "blurp" sound (very
technical, I know) every time you press a dtmf digit. I think what
is happening is that this combined with the in-band dtmf generated by the
gateway (dtmf should be out of band from phone to cucm to the gateway) can
cause all kinds of wierd problems on the receiving end. </span><o:p></o:p></p>

<p>more wide spread. They are G711, but thus far it's just one location
(multiple users) but they are the only ones that are using 7962 phones and
firmware <a href="http://8.4.1./" target="_blank">8.4.1.</a> Also.
I see a bunch of bugs for DTMF but they are all related to SIP / CTI but these
users are not using either of those.<o:p></o:p></p>
