see 'Path: [not set]' in the USRLOC table.
Is it possible to force the insertion of the local proxy into the path field?
Like Daniel already mentioned, add the header and msg_apply_changes() For example: https://lists.kamailio.org//pipermail/sr-users/2015-April/087872.html
One additional question, in the case of NAT keepalives, is it possible to only send these from the proxy the received the register request?
I decided to not use kamailio itself for sending these OPTIONS but to use a simple script that queries the database and simply opens a connection to the local kamailio. Mainly because I needed to monitor some UAC and alert when it wasn't reachable (even though it is present in location). In your case select the approriate UACs on Path.
while($location=mysql_fetch_assoc($res)) { usleep(1000); $branch=uniqid(); $send[$location['id']]=0; $dst=preg_replace('/.*@([^;]+);.*/',"$1",$location['path']); $dst=explode(':',$dst); if(count($dst)<2) { $dst[1]=5060; } $str=<<<EOS OPTIONS {$location['contact']} SIP/2.0\r Via: SIP/2.0/UDP 127.0.1.1:$listenport;branch=$branch;rport;alias\r Route: {$location['path']}\r From: sip:pinger@localhost;tag={$location['ruid']}\r To: {$location['contact']}\r Call-ID: {$location['id']}-$listenport-$uid@localhost\r CSeq: 1 OPTIONS\r Content-Length: 0\r \r
EOS; socket_sendto($sock,$str,strlen($str),MSG_EOR,$dst[0],$dst[1]);
Just to add, another option is to use the nat_traversal module: https://kamailio.org/docs/modules/stable/modules/nat_traversal.html. We use it for this very reason.
