[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.
