<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?<br>

I've found that increasing tone.dtmf.level on the Polycom phones from the
default of &quot;-15&quot; to &quot;-12&quot; or &quot;-9&quot; 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.&nbsp; 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>
