Missing 1 second of initial audio (callers don't hear<br>the beginning of the "please enter your pin" message).<br>It doesn't matter whether I move the session.answer()<br>earlier. This happens except for {teliax, landline, *}<br><br>You can avoid this by adding a sleep action to your dialplan<br>first answer the call from the dialplan and then use sleep to
run off 1.5 <br>lead-in seconds to avoid missing some of the audio<br><br><action application="answer"/><br><action application="sleep" data="1500"/><br><action application="conference" data="???"/><br><br><br>2. Doubling (and tripling) of incoming dtmf digits.<br>It is quite hard to get it to accept a pin, because<br>it keeps thinking I've entered a digit twice, when I<br>haven't. As far as I can see, there is no user configuration<br>to tune dtmf configuration (like min/max length of a tone,<br>or echo cancellation).<br>I also don't know if there is a way to force freeswitch/sofia<br>to use only a particular dtmf system.<br>Note that the problem seems worse when running javascript<br>confroom.js, but it happens both ways.<br>This happens with both ITSPs.<br>I see it except for {*, landline, native mod_conference.c}.<br><br>Like Mike said, we are only getting the DTMF as rfc 2833 and it has been<br>tested to parse the packets with a duration of as
little as 1ms up to several<br>seconds with accuracy. As a receiver of rfc2833 there is really nothing to tune<br>but I know all too well from to much time using rtp that a disagreement in<br>the protocol could cause some issues so I recommend you take Mike up on his<br>offer to investigate it.<br><br><br>Any suggestion for causes, fixes, ways to diagnose further,<br>etc., are welcome.<br><br>-mda<br><br><br><br><br>_______________________________________________<br>Freeswitch-users mailing list<br>Freeswitch-users@lists.freeswitch.org<br><a target="_blank" href="http://lists.freeswitch.org/mailman/listinfo/freeswitch-users">http://lists.freeswitch.org/mailman/listinfo/freeswitch-users</a><br>UNSUBSCRIBE:<a target="_blank" href="http://lists.freeswitch.org/mailman/options/freeswitch-users">http://lists.freeswitch.org/mailman/options/freeswitch-users</a><br><a target="_blank"
