Many people on this list will advise you to use a SIP proxy like 
OpenSER in front of Asterisk to take care of SIP registrations - I'll do 
the same. ;->

Looks like you've just decided to move to FreeSwitch ;-> While "early 
testing" shows that 1.6 can increase SIP performance compared to 1.4 up 
to factor 3-4, this release is by no means a from-the-ground-up re-write 
like FreeSwitch.
