A long time ago i tried to make one big iax2 trunk for one of my customers, i soon changed this to several small trunks. (bandwith doesnt rise all that much if you use 2 trunks instead of 1.) Asterisk didnt seem to like my big trunk very much (i don't remember how big it was, but probably over 100 calls).

Its a very long time ago, maybe some of those issues are resolved by now.

I am curious if anyone has had problems trunking iax2 with 100+
concurrent calls.  I am planning on testing this out tomorrow, however I
wanted to know if anyone else has had a problem with this prior to my
test so I know what to look for if anything is known and what
resolutions have been found if there are any known problems.

Specifically I am doing this on fbsd 6 with asterisk 1.2.4 using g.729
(bandwidth calculators suggest 0.8Mbps used with this setup, compared to
the 2.3Mbps (calculated averaging 2.25Mbps so its close enough).  That
is a considerable savings, not to mention that there will be fewer
sends/recvs so hopefully less irq time spent accessing the ethernet
card :)

I am just concerned with packet sizes in call quantities this large, and
other factors.

Anyone that has done this before I would appreciate hearing from you.
