New subject: controlling presence with new module `pua_json`

29 Aug 2019

      Hello Bill,
(please keep the list in CC)
yes, this seems to be the case. Just looked briefly to the code, it does 
an assignment in some cases. E.g. if no Presentity* data is given it 
will just use the From* information. And then it should later output an 
error from pua_json_update_presentity(..) if there is not the necessary 
data. Do you see any error message like this?
Another idea - does it works if you add more "missing" data in the curl 
requests?
Cheers,
Henning

Henning: Good point.
I do see a number of errors in the log. It looks like the json routine 
is looking for data that is not in the http query as specified by the 
author.

Hello Bill,
just giving some generic debug pointers here:

do you see any errors in the kamailio log file?

do you see any SIP traffic (e.g. by observing with ngrep, wireshark

etc..) to the phone after your curl command?
Cheers,
Henning

Hi all:
I am trying to use the procedure for setting BLF lights described in
https://blog.voipxswitch.com/2018/02/22/kamailio-controlling-presence-with-n...
WIthout success.
My configuration is 1 Grandstream GXP2130 phone behind a NAT on a
public IP. (IPP in example below)
Kamailio is running on public IP (IPK in example) listening on port 
50060
The command I am sending:
curl -d
'{"Call-ID":"1020101@<IPP>","Event-Category":"presence","Event-Name":"update","Event-Package":"dialog","Expires":"3600","To":"sip:1020108@<IPK>:50060","To-User":"1020108","To-Realm":"<IPK>:50060","From":"sip:1020101@<IPP>","From-User":"1020101","From-Realm":"<IPP>","State":"Confirmed"}'
http://localhost:8080/presence/
{"Call-ID":"1020101@<IPP>","Event-Category":"presence","Event-Name":"update","Event-Package":"dialog","Expires":"3600","To":"sip:1020108@<IPK>:50060","To-User":"1020108","To-Realm":"<IPK>:50060","From":"sip:1020101@<IPP>","From-User":"1020101","From-Realm":"<IPP>","State":"Confirmed"}
Kamailio appears to be processing the command OK, so I think I am just
not setting it up properly>
Anybody having any luck with this procedure, let me know how you are
getting it to work.
Bill
