asterisk users - Apr 2005 - SPA and NAT traversal

I was hoping someone might help me diagnose a NAT issue with an SPA-2000 and
my * server.  

My SPA is behind a NAT accessing a server which is also behind a NAT but SIP
and RTP ports are forwarded to it.

My SPA can successfully register.  It can call another extension which is
inside the * local net and the inside phone can call the SPA.  But, no
speech path either way.  I have NAT=YES and the two invite parameters are
set to NO.

Thoughts?

I'm desperately trying to get your sip.conf file telepathically but 
all I'm getting is images from your Martha Stewart porn collection. 
*shudder*

In addition to nat=yes you also need localnet= and externip= set, as 
shown in sip.conf.sample.
