Hello Anca.
I have modparam("presence", "force_active", 1) in my config file but there is no message body being generated.
I suppose I am a little confused on exactly how the new presence module is supposed to work and hopefully someone can help explain. Here is the way I understand it to work:
Let's say I have 2 Polycom phones, 1000 and 1001. Say that 1001 sends a SUBSCRIBE to openser for 1000. Openser then makes note in the active_watchers table that 1001 wants to know about events for 1000. Openser then generates and sends NOTIFY messages to 1001 when things change for 1000. Where I'm confused is what criteria are being used to generate the NOTIFY messages? Is it based on registration state or are the NOTIFY messages generated based on active SIP dialogs? For example, if 1000 is active and on a call, in dialog, by virtue of it getting a INVITE and then sending a 200 OK, does openser then send a NOTIFY to 1001 telling it that 1000 is busy so that 1001 can display this however it chooses? I'm just confused as to what is triggering the NOTIFY messages which are sent back out to the subscriber. Do the pua modules serve some role here? Specifically, does the pua_usrloc need to be used?
Also, since the new presence modules have been introduced, is the older pa module going to be depricated or will it continue to be developed? Presently in 1.2, I cannot get pa to work as the database structure is not correct, at least for postgres.
Sorry for all of the questions, I'm just really having a hard time trying to figure out how all of the presence modules work together with the openser core to provide presence functionality.
Cheers, -Curt

Hello,
Presence module does support xpidf type. What I am guessing is that you have not set the force_active parameter to 1. This is why the Notify messages have no body. Set the parameter in your configuration file and try again.

Hello all.
I've been experimenting with the new presence module in openser-1.2 and have a few questions which hopefully someone can help answer.
I'm using an SVN checkout of the 1.2 branch, r2237, and am testing with Polycom SoundPoint IP phones, firmware 2.1.1.0052.
From what I can tell, openser 1.2 does not fully support the xpidf
content type, it only supoorts the winfo content type. I've looked through the code for the presence module extensively and it appears that whenever a SUBSCRIBE comes in where the Event header is simply "Event: presence" and the Accept header is "Accept: application/xpidf+xml", the message is acceped and a 202 is sent in reply but in any NOTIFY sent from openser as a result, there is no message body and the message does not contain the XML information for pidf.
Just as a test, I changed the event field in active_watchers to "presence.winfo" and noticed that with this change, openser generates a NOTIFY with a message body which contains watcherinfo. This, of course, generates a 481 from the phone since it does not know about the "Event: presence.winfo" event type.
Also as a test, I tried to use the pa module as I'd had success with this module in the past since it _does_ support xpidf. In 1.2 it appears that the database structure specified in the databse setup scripts does not agree with the table structure being used in the module. As a result, I could not get the pa module to work either.
Am I overlooking some small detail?
Please let me know if further information is needed in order to help diagnose and resolve this issue.
Cheers, -Curt
