[Asterisk-Users] Registering Softphones to Asterisk

The examples in the onlamp article are sufficient to allow a 
standards-compliant SIP phone to register with your Asterisk system. 
This is really a question about your particular softphone, and not 
about Asterisk.  I'd suggest grabbing a copy of the xten Xlite 
(http://www.xten.com/) phone and seeing if that registers 
successfully, as I have that one working quite well.  For testing, 
make sure there are no NATs or firewalls in between your Asterisk 
server and your client.
