Summary:                    [patch] Response to REGISTER is sent to wrong
address when using rport
Description: 
I have client behind NAT. 
when client (10.0.0.17) sends REGISTER request, it puts rport into Via
header. check_via notices that and sets SIP_NAT_ROUTE to the &p->flags[0] -
note the log line:

Sending to 192.168.7.211 : 5079 (NAT)

however the register_verify function later does 
  ast_copy_flags(&p->flags[0], &peer->flags[0], SIP_NAT); 
effectively overwritting the value with SIP_NAT_RFC3581. And finally,
check_auth send response back to client to the wrong address which is
visible from the log line 

<--- Transmitting (no NAT) to 10.0.0.17:5079 --->

I wonder if there are at least any plans to fix the issue.
I just upgraded to 1.6.2.13 and I see exactly the same behavior - the
response to initial REGISTER is sent to the unreachable address
(192.168.x.x)....
