I presume you're looking at the asterisk console (ie. started asterisk with
option -vvvc) ?

If the regisstration went correctly you should see 'normal' call behaviour
in your client, the client calls the number and thinks the call is
connected. Also you can issue : 'sip show peers'. It should give you
something like :
*CLI> sip show peers
Name/username    Host                 Mask             Port     Status
sipphone/xxxxxx  130.94.123.252       255.255.255.255  5060     Unmonitored
xlite            (Unspecified)   (D)  255.255.255.255  0        UNKNOWN
fwd/username     192.246.69.223       255.255.255.255  5060     OK (155 ms)

I'm guessing you have succesfully opened the portranges needed in your fw
config? If so you also need the sip->nat patch by Leif Madsen. There has
been a topic for the last two weeks (subject : [Asterisk-Users] Asterisk
behind NAT << How to do it.). Look at this thread, install the patch and you
should be fine.
