[Freeswitch-users] mod_portaudio send 3 rtp packet/60ms instead of 1 packet/20ms

[Zelei Csaba]

Dear all,

I tried to use FS in client mode, starting calls with mod_portaudio to our
providers gateway ( a Cirpack softswitch )
I experienced that there is 2-3 sec delay in the call, its choppy and robot
like.
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
