<p class="MsoNormal"><span style="font-size:10.0pt">We are using Freeswitch with Sangoma T1 cards to bridge TDM with our internal VoIP system. Call flow is as follows:
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt">PSTN --> T1/Sangoma cards --> Freeswitch --> IVR
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt">I have configured Freeswitch for
<span class="bold1">RFC2833</span>. When I make a call to the IVR from a landline or cell phone and press "5" at a prompt, FS will sometimes send two separate
<span class="bold1">DTMF</span> events to the IVR. This causes the IVR to receive "55" which then sends the call to the incorrect destination.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt">I can verify with Wireshark that FS is sending two separate
<span class="bold1">RFC2833</span> events. For some reason, this is exacerbated with heavy call volume (easy to reproduce during load testing). Has anyone experienced this symptom or have any ideas what I can check?
