[Asterisk-Dev] Benchmark numbers....

[Zoa]

I can confirm the numbers Brian posted here, and can also confirm the
problems with sip.conf entries and iax.conf entries.

Sip registrations can be stresstested with tools like sipsack and sipp,
for stresstesting iax2 registrations we wrote something a while ago, go
find it at : http://www.astertest.com/downloads/iax_mass_authorization.tgz
