Voip Over low bandwidth leased line

Is there anyone who knows how many maximum concurrent connection that a 64K leased line can accomodate.

Thanks,

Andy

Re: Voip Over low bandwidth leased line

Andy,

As ever: it depends.

If you are use 8K compression and compressing RTP and TCP headers then each voice conversation comes out at about 12K per call.

It is recommended that you don't use more than 75% of the bandwidth available for voice, so 4 x calls would use 48K.

Of course if you use VAD then you could argue that each conversation is only using the bandwidth 40% of the time - but I wouldn't ever use more than 3 or 4 calls over a 64K channel.

3 is my gut reaction, 4 is technically feasible.

Rgds,

Thanks Stuart,

One more thing, when you say 12K per call does it means that it is the maximum bandwith consume of every conversation. So eventhough both party were talking simultaneously you only consume 12K max.

Thanks

Andy
