Hi Aqs;

Checking with full debug on I can see that the publish appears to be created. 
udp_rcv gets the publish (source IP is servers public IP 5.6.7.8:5060). From 
what I can see the AUTH route is sending a proxy auth challenge.

5(5525) received on udp socket: (106/100/1017) [[PUBLISH 
sip:2...@mykamailio.com SIP/2.0 0D  0A Via: SIP/2.0/UDP 
5.6.7.8;branch=z9hG4bK0ae2.85bf70]]

5(5525) received on udp socket: (106/100/526) [[SIP/2.0 407 Proxy 
Authentication Required 0D  0A Via: SIP/2.0/UDP 
5.6.7.8;branch=z9hG4bK0ae2.85bf70510]]

I think it’s getting caught here;

route[AUTH] {

        if (is_method("REGISTER") || from_uri==myself)
        {
                # authenticate requests
                if (!auth_check("$fd", "subscriber", "1")) {
                        auth_challenge("$fd", "0");
                        exit;
                }



So that looks like the first issue.   If I patch AUTH route to allow through 
anything with the servers source IP (A bit dangerous as someone could faking IP 
source on UDP. is there a better way?) the proxy_challenge no longer gets sent 
and I see what I think is it trying to send a notify to the watchers phone;

send_notify_request(): NOTIFY sip:2...@mykamailio.com via sip:1.2.3.4:5065 on 
behalf of sip:2...@mykamailio.com for event dialog : 2862418150@10.1.3.84

However it doesn’t come out of the ethernet port (sngrep) and I can’t see any 
obvious failure.  Although that may be me as I’m still trying to follow debug 
logs!

Given the line above is there a way to trace it?

Thanks!

Best regards
Mark
