Registration should occur across udp 5060 only.

I don't use a cisco pix, but I believe their is a config command like
"sip fixup" (or something like that). Supposedly, the pix will look
inside the sip packets and watch for the rtp port negotiation, and then
open those udp ports as appropriate.

You might check the pix documentation to see exactly how the sip fixup
is to be used/defined.

In asterisk, you might need "nat=yes" for the external use of xlite.

To get more detail as to why the registration is happening correctly,
you might want to try "sip debug" and pay attention to IP addresses,
error messages, etc.
