It looks like the phones are sending the dtmf digits in-band as well as out of band and this is what causes the double keypresses. It also appears this behavior changes depending on if you are using the handset/headset/speakerphone. </font></span></div>

<div dir="ltr" align="left"><span><font face="Arial" color="#0000ff" size="2">I was doing some work on this Friday and there is definitely some noise generated in-band by sccp phones on 8.4(1). If you take a packet 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. </font></span></div>

<p><span style="FONT-SIZE: 11pt; COLOR: #1f497d">I am also running into some DTMF issues at an installation I am currently doing utilizing 7962s on the latest firmware (SCCP42.8-4-1SR1S) as well as 7942s on firmware SCCP42.8-4-1SR1S. However, I am using MGCP on my gateways. I've got various users running into issues with unrecognized digits, multiple digit presses, among other things. I'm actually glad to see a few others are having this issue as the reports at this install have been popping up a little more often.</span></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.</p>
</div>

<div>
<p>Any more ideas?</p></div>
