Reply To: VoIP bandwith one way or two way


Hi! i have a similar doubt about VoIP.Right now i’m doin’ a ‘project’ about this issue and im quite confused with the bandwith requirements as well.Using a G.711(64Kbps) or G.729(8Kbps) codec, which will be the new bandwith including RTP/UDP/IP headers?? 80Kbps per each direction in G711 case???in G729???.
If i have to offers full VoIP service to 648 customers in the rush hour at the same time, what kind of gateway do i have to buy??How do i know de number of customer it can give service to?how many calls can it support??…thank u
