as you can see here: http://jira.freeswitch.org/browse/MODENDP-40 <http://jira.freeswitch.org/browse/MODENDP-40> i have this problem all the time (the error mentioned in this issue was only related with this). It has to do with windows handle sleep() method, you has say sleep(1) for 1ms but on my machine it waits 15ms (it depends on your hardware, other PCs behave different!). So i tested around with high performance counters. For now i ignore that problem an set jitterbuffers on other device big enough.

I tested it with a softphone, and an ip phone and everything was fine. I traced back the problem to mod_portaudio sending 3 rtp packet in 60ms instead of 1 packet/20ms. Here is an rtp statistic from a call: (see http://pastebin.freeswitch.org/4307 for the complete list and sip trace) Packet Sequence Delta (ms) 42 26138 0.00 43 26139 0.02 46 26140 45.69 47 26141 0.02 48 26142 2.96 52 26143 56.31 53 26144 5.75 54 26145 0.02 58 26146 51.99 59 26147 0.03 60 26148 2.96 63 26149 42.95 65 26150 17.06 66 26151 0.02 67 26152 2.90 71 26153 56.99 72 26154 0.03 73 26155 0.02 Did anyone else experience similar problems? Is this the desired behaviour, because portaudio get data in 60ms interval or can I set it to 20ms somehow? Thanks, Csaba Zelei
