Summary:                    [patch] [SIP realtime] "sip reload" makes
UNREACHABLE users behind NAT
Description: 
When a SIP dynamic realtime user is registered behind NAT (with "nat=yes"),
a "sip reload" command makes Asterisk "forgetting" the public location of
the peer, and instead uses the private address of Contact header to reach
it. Of course it fails and causes the user to be UNREACHABLE.

    Use the address we already know when reloading a peer with nat=yes.
    
    If we already have an address for a peer, and we are reloading the sip
    configuration, try to use that address to contact the peer, instead of
    getting it from the Contact.
