[asterisk-users] IAX2 trunking scalability

[Jean-Michel Hiver]

Hi,

I thought I'd give a follow up to this discussion for the archives...

Currently I'm trunking 30 channels of g.729 traffic (no transcoding going  
on, the call comes in and goes out as g.729) and it takes about 350 kbps  
bandwith bidirectional.

So on average each call takes 11.5 - 12 kbps of bandwith. The solution  
seems stable and the QoS is identical... so for the price (2 commodity  
PCs...), IAX2 trunking is well worth the effort since it reduces bandwith  
usage by a factor of 2.

Cheers,
Jean-Michel.
