<div></div>I tried it with the latest trunk.<br>If I set it to 60ms sometimes I

low 15-30ms, sometimes too high 100-150ms delta (with codec-ms = 60ms), and with
15-20ms jitter.<br><br><br>Anthony Minessale wrote:
<blockquote type="cite">Have you tried setting the codec-ms in the portaudio.conf.xml to
60 or 120 ms?<br>Maybe the soundcard is not able to do 20ms intervals and
portaudio is doing the least common multiple and chopping it up for us.<br>I
think what's happening is the timer in the module is set to the interval from
the config file (20ms) and during every 60ms period there is no audio until
the last ms. so in each 60 ms:<br><br>20ms (timeout..... flush
buffer)<br>20ms (timeout..... flush buffer)<br>20ms (get 60ms worth of audio
at once [3 20ms packets] but we have already read 2 filler frames from the
timeouts)<br><br>So now we have read 5 packets instead of 3 and erased some of
our buffer because of perceived timeouts.<br>The code is using the assumption
that if the device will obey the chosen frame size and sample rate requests
down to the interval.<br><br>If you find and edit
conf/autoload_configs/portaudio.conf.xml<br><br>look for
this:<br><br> <param name="codec-ms" value="20"/><br><br>and change
20 to 60<br><br>Setting this to 60 will change the frame size of all the
packets from 320 to 960 and set the timer to clock at an interval of
60ms<br>Since the card seems to be able to reliably produce 3 20ms packets
every 60ms it should also be able to produce 1 60ms packet.<br><br>FreeSWITCH
should then buffer the audio and still deliver it over SIP at 20ms if you want
but you can opt to set the codec PCMU@60i to disable buffering if you are in a
reliable network.<br><br>The same should be true for setting the codec-ms to
120<br><br><br>
