Open Sound System Console Driver Configuration File

osss.conf file is comin g with asterisk for windows / Vista.

alsa.cong file is coming with asterisk for windows / Vista

Unfortunately there are no modules like

chan_alsa.so , chan_oss.so coming with asterisk for windows installation.

If not oss and alsa, so what module is responsible for playing back of audio files in asterisk for windows ?

I would like to configure it to get better sound quality and undistorted sound when using celliax + asterisk for windows to play audio file (by asterisk) in No-Serial mode (celliax.conf).

There is a number of manuals on how to configure alsa.conf on the net.

Unfortunately chan_alsa or chan_oss are not coming with asterisk for windows installation,
so what is a chance to get chan_alsa.so, chan_oss.so modules compiled for windows 32 ?

Adjusting jitter buffers
Jitter buffers trade off between sound quality and delay. A larger buffer means less jitter but more delay. You can buffer VoIP calls until the sound is perfect, but at the price of long delays. Start with 100 milliseconds, then increase it, as necessary, in 100-millisecond intervals. 1,000 milliseconds is the maximum practical value; you'll notice it, but it shouldn't be too horrid.

The Asterisk jitter buffer is linited to the IAX channels at present, but starting with version 1.4M is going to be all shiny and improved—and support more channels. Version 1.4 is still in beta, so feel free to download and play with it, or just read the documentation in the tarball. For now, we'll stick with the 1.2 jitterbuffer (as Asterisk refers to the jitter buffer) configuration. Open /etc/asterisk/iax.conf and go to the jitterbuffer section:

; You can adjust several parameters relating to the jitter buffer.
; The jitter buffer's function is to compensate for varying
; network delay.

Here is a sample configuration:

jitterbuffer=yes
maxjitterbuffer=1000
forcejitterbuffer=no
maxjitterinterps=10
resyncthreshold=-1
