asterisk users - Nov 2005 - Realtime IP peer with static IP won't load

In CVS Head from both 2005-08-28 and 2005-11-03, I've created a SIP peer
and user with the same settings.  When this peer/user sends a SIP invite
to the asterisk system running realtime, it gets a 404 not found back,
and the realtime system says it's unable to find a match for
<ip-address>:5060.  However if I forcefully load the peer by using sip
show peer/user <name> load.  Then everything works just fine.  Also if I
set the peer/user as a dynamic IP address, when it registers, the
realtime entry is loaded.

This seems like bad behaviour for the SIP realtime peer/user with static
IP address.  Has anyone else experienced the same?  Is there a special
configuration of the realtime config settings in sip.conf that enables this?
