[Asterisk-Users] Is There Media Accelerator For Better Asterisk Calls

[chawki hammoud]

Dear Asterisk Users:

Please give me your opinion or advise of how I can
optimize my internet bandwidth to get better calls.

During morning hours, calls are fine. But during high
traffic time, I have calls problems. So I experimented
with changing the codecs in iax file and monitoring
the internet bandwidth using Mandrake linux control
Ctr.
When I used ulaw, the sending speed rate was at 9.3
Kbs and people can hear me fine. The receiving speed
rate was oscillating around 5kbs and 9.3 kbs where at
9.3 kbs the quality of the call is good. If I changed
the codec to a less bandwidth codec like gsm, the
sending speed is 3.1 kbs and people can hear me fine
and the receiving call alternates around 1 kbs and 3.1
kbs where at 3.1 kbs i can hear people fine. In both
codecs I experienced breaking up sounds when the rate
goes beyond 9.3 and 3.1.

The bandwidth for gsm is there, as it showed in ulaw.
Why gsm can't use the bandwidth consistently. Can I
download something like a media accelerator? Please
tell me what you think. Any suggestions.

Thanks;
