I use IAX2 trunk between two asterisk server. 
At  a few calls (less than 30) enviorment, both caller and callee hear each other clearly. But when calls reach 45 or above, the quality of sounds is bad. 

I wonder if a IAX2 Trunk should limit concurrent calls?

I use ILBC codec in the trunk.

any idea?

btw: I use asterisk-1.2.12, zaptel-1.2.8
