Bandwidth for 4 VOIP lines


With asterisk… how good is its compression vs quality with limited bandwidth?

I’d like to know how much bandwidth could be required to support 4 concurrent international calls via a single internet line.

Internet speed is approx. <32kbps… is this good?

Kind regards,


Are you saing that you have less than 32 K of bandwith and you are hoping to get 4 calls up it !

Basicly the ethernet overhead for 4 calls will almost be 32K

You may be lucking and get one compressed call down it but it will suffer with Jitter and latency realy bad.
