<p class="MsoNormal">I’ve got a customer that is experiencing issues
with
DTMF recognition when utilizing Webex Conference services. I have
adjusted DTMF
length and level to the point that it is causing issues with some other
services but they are still reporting failures. I can intermittently
replicate
the issue as well. Anyone experience anything similar? Thoughts?<o:p></o:p><br>

I've found that increasing tone.dtmf.level on the
Polycom phones from the default of "-15" to "-12" or "-9" often helps
with problems where conference bridges, IVR systems, etc. aren't
receiving some/all of the digits.<br>
<br>
If that doesn't help, you will need to work with L3 support. They have
had numerous DTMF issues with their gateway vendor over the years, and
you may be running into the next in a long line of bugs from them.<br>
