Hello All,

Wondering what sort of real world mileage people are getting out of different internet connecions - i.e. different DSL connection speeds, cable modems, etc... Is it reasonable to hope to carry 10 - 15 concurrent calls on a 768K DSL? I'm not talking about theoretical BW or looking for any difinitive absolute guarantee... With DSL and Cable - there is no guarantee, so I'm wondering what folks are getting with real world usage...


I do up to 10 g.729 channels over 1024 / 256 DSL without noticeable difference in call statistics (i.e. avg length of calls). If you are using ADSL, the maximum bandwith you'll be able to use is your upload rate since VoIP calls send data bidirectionally.

Snip ...

Jean-Michel, hi;

Is that using SIP or IAX2 ? I'd assumed you'd be able to get more than that throughput out of an IAX2 trunk because of the sharing of RTP overhead ?
