Yes, but
1500 calls
3000 call streams
50 pps per call stream
thats 150.000 pps + signalling, we need double the packets per second on 
that machine to have that amount of calls. (sure the test is not 1500 
call legs?)
 
Yes, linux can do that in the kernel on that machine, the intel e1000 
networkcards can handle that kind of traffic but i can't believe a 
userland application can do it.

Another question : could somebody tell me if the dtmf mode setting in 
sip.conf is only used for how to send dtmf to the end point or also if 
asterisk has to look for inband dtmf on the incoming packets ?
Is asterisk always looking for inband dtmf ?

BKW, my gut tells me that server will handle over 60 call setups per 
second on asterisk, but not when running on nearly 100% cpu, so you can 
do more call setups per second in the beginning of the test, but when 
nearing the maximum throughput of rtp, callsetups need to be less to be 
able to complete the max throughput test.
