Way back in the day, many UNIX systems authenticated users by IP 
address, then SysAdmins figured out it was a bad idea. (IP addresses can 
be spoofed.)

None the less, how are you recieving incoming calls? A guest account? 
host= in sip.conf & iax.conf applies to the client, not direction of 
call, so it should work fine.
