Re: [Asterisk-Users] internet bandwidth

[Vahan Yerkanian]

As an additional info, G723 is like 1700 bytes per second, GSM is like 
4600-4800 bytes per second as viewed by netstat - those numbers are with 
 ip overhead. I've been able to use a dialup as a link to get 2 
simultaneous G723-based sip hardphones to * server.

Hi Hammoud,
 
It all depends on the codec that you are using. Best case scenario is 
with G723 codec 6.3Kbps per channel * 20, around 126K without the 
overhead. But you problably won't be able to use this codec unless you 
are in passthru mode (license is pretty expensive).
Using g729 you will be using 8K so a total of 240K+ total bandwidth 
(passthru OK but you can purchase the license from digium)...
