asterisk users - Feb 2006 - Asterisk & Broadvoice Incoming Calls Problems

Hi, i'm having problems with broadvoice incoming calls. I can perfectly
place calls but my Asterisk Box is having problems when registering with the SIP
Proxy. Sometimes it register and the call gets into asterisk, but without sound
(seems to be NAT problems) and sometimes its not possible for asterisk to
receive the calls. Everything was working great exactly for a month, but a week
ago it crashed and stop working. I dont know if someting happened with the
broadvoice service or the problem is mine, cause i tried with the same setup it
was working.
Im behind a NAT Firewall, so i need a setup that can work in this condition.
Here is part of my setup:

sip.conf
externip=200.42.xxx.xxx
nat=yes


register =>
305xxxxx22@sip.broadvoice.com:MyPassword1:305xxxxx22@sip.broadvoice.com
register => 
305xxxxx66@sip.broadvoice.com:MyPassword2:305xxxxx66@sip.broadvoice.com
