this load tests are mostly about sip signal handling and not so much
about rtp streaming but this moh class which i use had 100 files and
random set to yes, so its atleast not soo bad.

This 330 concurrent calls was only the highest value which i had on a
normal production system and its really hard to build a test setup which
presents a system with 4000 sip peer doing some calls.

but the sound quality was still good even with 10000 calls in my tests.
