Hello Everyone,
In my case I am using Path and I asterisk generate NOTIFY with route based on path, then I see on kamailio side tries reach on client on public IP side and open new connection not follow ESTABLISHED/RELATED link then it times out.
Log:
Mar 23 11:00:17 canlvprx01 /usr/sbin/kamailio[20193]: INFO: <script>: [NOTIFY], Inbound connection from <10.18.130.51> traffic from Asterisk
Mar 23 11:00:17 canlvprx01 /usr/sbin/kamailio[20193]: INFO: <script>: [NOTIFY], Present Route: Client_public_IP.

Anthony,
The Contact presented by the subscriber in the initial subscription is:
m: "Test User"
<sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84OC82LK-2ehwl7NYDdNYDxNYlFUAm6UYzm0gme>;+sip.ice
And the subsequent NOTIFY is correctly targeted to this RURI:
NOTIFY
sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84OC82LK-2ehwl7NYDdNYDxNYlFUAm6UYzm0gme
SIP/2.0
The subscriber returns this Contact in the 200 OK response for the NOTIFY:
m: "Test User"
<sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84O>;+sip.ice
And subsequent NOTIFYs appear to use this RURI instead of the original
Contact of the subscriber:
NOTIFY
sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84O
SIP/2.0
NOTIFY
sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84O
SIP/2.0
etc.
A SUBSCRIBE is a dialog-creating event, so in-dialog messages (e.g.
NOTIFYs) should be targeted at a Request URI corresponding to the
Contact URI of the SUBSCRIBE-er. It seems to me that this is the problem
here, rather than truncation.
