[asterisk-users] concurrent channels limit

No, I don't do transcoding, I've disabled all the codec except for the g729.
But in my last test I've found out what is the problem (not yet how to 
solve it)
I make all my calls through a php agi, this old script works well on 
asterisk 1.4 and I want to move on 1.8.
Just for test I've created three different (simplest) scripts:
1 - stream a file codified in g729
2 - make some mysql queries and stream the file
3 - make an http hit and stream the file
I stream an audio file to create calls that last some minute and test 
also the audio quality, I don't know if there's a better way.

Anyway, if I use one of this 3 agi (also randomly) I'm able to establish 
up to 2500 channels with a perfect audio.

If I use my old agi I could establish just 74 channels. I'm going mad on 
this because the number is not variable, is not one time 80 and the 
other 70 and sometimes 88, it's always 74.
The old agi script is a little longer than my test scripts, but it make 
the same things.
I could accept the loss of some channels, but from 2500 to 74 there is a 
difference a little too big.
