[Kamailio-Users] pua_bla and presence - sr-users

30 Jul 2008

Hey,
I have the same problem , using the same openser configuration file, only
adding  pua_bla "server_address" parameter on  1.3.2 bla stop working.

I installed 2 openser once with 1.3.0 and the other with openser 1.3.2, then
start openser using full debug log level to see what happens with each one.

I'm using Polycom 650 hardphones

Basic console error log
-------------------------------------
 ERROR:pua_bla:bla_handle_notify: content length= 0
 WARNING:tm:t_unref: script writer didn't release transaction
http://pastebin.com/m4a1b7969 (OpenSER 1.3.2 debug logs)

Full debug log
-----------------------
http://pastebin.com/m177c219a  (OpenSER 1.3.0 full log)
http://pastebin.com/m36f3ffca   (OpenSER 1.3.2 full log)

The main difference that I saw comparing both logs are remarked in pastbin,
and refer to: "DBG:pua:print_subs: pres_uri"

Please see below both configuration parameters

I'm sending configuration of affected routes  (Main, Register, Presence) so
you can see if there is an error.

route {

Ok, I hope that provided information help to see if there is a problem on my
configuration or a is a bug on OpenSER 1.3.2

Thanks in advance,

Cheers,
