Hi All

Got a presence problem with what should be a very simple config.

Would much appreciate someone having a look at the following and seeing if I’ve missed something obvious :-)

Thanks
Mark



I’ve gone right back to basics and using the example at http://kb.asipto.com/kamailio:presence:k43-blf

Changes to that example are;
- Kamailio 5.1.2
- RTPEngine
- NAT Enabled
- JSON RPC replacing mi_rpc
- HA1 Passwords


Setup is; 

Three phone 20,21,22 all on site behind a NAT (10.1.3.x local IP) at 1.2.3.4 External IP.

Phone 21 has BLF Subscriptions on 20 and 22

Domain is set as “mykamailio.com”

Kamailio is an Ubuntu server “In the cloud” on 5.6.7.8

(Assuming I have got my domain & ip rewrites correct on the cut’n’paste)



What’s Happening;

All three phones register

21 Issues SUBSCRIBE:Dialog for 20 and 22.  Which get 202 Accepted back after a 407 Proxy Auth

I can see these arrive in active_watchers table;

*************************** 2. row ***************************
              id: 2
  presentity_uri: sip:20@mykamailio.com

  watcher_domain: mykamailio.com

         updated: -1
   updated_winfo: -1
           flags: 0
      user_agent: Yealink SIP-T26P 6.73.0.50



If I make a call from 20 to 22 it works as expected but no notify is sent.



For completeness the changes I’ve made to the kamailio.cfg file are;
