When doing the packets, can you also monitor the bandwitdh used ? As i 
pointed out before, SIPp does not generate audio and asterisk will not 
send audio packets unless packets are received.
(This does conflict with the fact that you see higher load when 
transcoding is used).

400 transcodings is about what i would expect for the cpu's, but the 
1500 simultaneous calls is more then i would expect from linux user land 
packet handling on that system.
Did you do any tweaks with the kernel or cpu affinity for this ? What 
network card are you using ? On top load, how much is going to system ? 
What kernel are you using ?
