Summary:                    Peer address always overwritten by contact address
Description: 
In asterisk 1.6.2.17.3 setting nat=yes in sip.conf resulted in the ipaddr
field of a realtime peer being used as the addr field in the sip_peer
structure.

In asterisk 1.8.3.3 I'm seeing that the address in the fullcontact field
is being used regardless of the nat setting in sip.conf, except during
registration when the rport option is present.

I've attached a patch (against 1.8 svn) that uses SIP_NAT_FORCE_RPORT for
the overwrite check in build_peer instead of SIP_NAT_RPORT_PRESENT.
SIP_NAT_FORCE_RPORT is set by the nat option in sip.conf and appears to be
what most users of the 1.6.2 flag SIP_NAT_ROUTE were changed to.
