<p class="MsoNormal">One of my co-workers just migrated from a Samsung phone to a Pixel 5 phone.<o:p></o:p></p>
<p class="MsoNormal">An app on the phone dials into our asterisk.<o:p></o:p></p>
<p class="MsoNormal">He has the same app installed on both and can move the SIM card between them.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Call is answered and a prompt plays to collect digits.<o:p></o:p></p>
<p class="MsoNormal">The app dials a number followed by a pound (example 1234#).<o:p></o:p></p>
<p class="MsoNormal">Asterisk and our AMI based application sees this and everything is good so far.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Another play begins to ask for another set of DTMFs.<o:p></o:p></p>
<p class="MsoNormal">Milliseconds after asterisk starts playing, it is reporting the DTMF # ended a second time. The RTP is showing no new # being sent (1-2 seconds later phone dials digits for this second query)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What I determined when listening to a comparison of a tcpdump and the RTP streams:<o:p></o:p></p>
<p class="MsoNormal">Samsung has an interdigit timeout to the point you can hear a delay between the digits. Just from listening, probably 150-200 ms between digits.<o:p></o:p></p>
<p class="MsoNormal">When listening to his Pixel 5 phone’s RTP, the digits are speed dialed. From listening, either there is no pause between digits or it is extremely small.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is PJSIP and DTMFs are inband.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Are there any configuration setting in asterisk to adjust the amount of time between digits?<o:p></o:p></p>
<p class="MsoNormal">Any suggestions that I can try?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
