<p class=MsoNormal>Guys<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a customer that is having a strange issue with DTMF<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>As you know, Arc is a CTI application (using the CiscoTSP –
different to JTAPI or Unity). When a call comes into the Arc IVR product from
an external route (all of which are SIP Trunks), the DTMF digits are not being
received. It works fine if you call into the system from an internal phone…<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Unity also works fine – however that’s a different
integration point<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Cisco Developers can see the issue, and have advised that it
is because the DTMF is set to in-band, which the CiscoTSP/CTI Port does not
support – and that DTMF must be set to out-band<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However, the customer is sure that DTMF is set to out-band
already.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Does anyone have any experience with this – any pointers? I
believe the partner has raised a case with TAC as well<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
