<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I have a client with 30 extensions, all Polycom 501 phones, an Asterisk<br>
<a href="http://1.2.30.2" target="_blank">1.2.30.2</a> installation, and trunking over SIP to TelIAX. Everything works<br>
fine except where they need to use DTMF to navigate IVRs such as<br>
Dell.com. The tones are not recognized at all.<br>
My sip.conf lists for each extension:<br>
<br>
dtmfmode=rfc2833<br>
<br>
and in the [general] section: relaxdtmf=yes<br>
<br>
I have a very similar system at my office nad DTMF works.<br>
<br>
Any ideas why this does not work?<br>
