asterisk users - Jun 2007 - Help with IAX Trunk

Hi

I've two servers :

1. UK
2. Pakistan


Pakistan * server has ISDN30.

Pakistan(ISDN30) <====> UK ===> User

Im planning to setup an IAX2 trunk between these two server ?

so , how much bandwidth I need for 30 simul. calls ?

Im planning to use G729 on both my server ?

to support 30 calls over IAX2 do I've to change some setting during compile
time or not ?

pls suggest.

thanks

If you're using IAX2 trunking, the bandwidth requirements will be much
less than if you're not using IAX2 trunking.  Make sure you have
trunk=yes in the peer definition in iax.conf.  Off the top of my head
(without actually running the numbers), I would guess that 30
simultaneous calls using the g.729 codec and using IAX2 trunking would
take less than 512kbit/sec in each direction.

No, just make sure you have a suitable timing source (Digium card,
ztdummy, etc.) for the IAX2 trunk.
