[Asterisk-Users] Confused !

[AR Tarzi]

I'm not an authority
but why don't you get some g729 codecs (10 or so) and use g729 all around.
Not allowing for ADSL overheads you can calculate your own requirements on
http://www.asteriskguru.com/tools/bandwidth_calculator.php (please double 
the results since each call is turned around to your service provider.)

I would have thought it would be better if you could use reinvite to let 
your clients speak directly to your service providers. Someone who knows 
better ought to be able to tell if this would work.

Your restriction is what the service provider allows. Most (that I've used) 
allow g729. I know it uses more bandwidth than g723 but nothing like G711 
(ulaw or alaw) and from my experience, the quality is quite reasonable.

thanks for your replay,

after i disallow all codec except g723 i also confused how a2billing
is working then what i did , i removed all the codec from
/usr/lib/astersik/module without codec_g723.so .

then i saw in my log while user calling to my ivr access number a2b is
looking for gms codec as all the audio file is in gsm format. but what
my understanding was it should drop the connection as i only allow
g723 .

what is found today from one of my frnd telling me that actual
bandwidth calculation

"
For codec g723 incoming and g723 outgoing we need: 48.89kbps
For codec g723 incoming and g711 outgoing we need: 114.03kbps

So, to run 8 calls we will require 902.15 kbps or 0.9 mbps
For 10 calls we need 1140.3 kbps or 1.1mbps

Each call has RTP, UDP, IP, Codec and SIP overhead.
"

so what u guys suggest , should i record all my ivr file in g723
format all . increase my bandwidth!
