Hello Francisco,

somehow I missed that patch, thanks for reminder! Is it against sip-router or kamailio 1.5.x?

I checked it quickly and the only thing that does not seem ok is how the r-uri is taken in modules/dialog/dlg_handlers.c:

- instead of:

+	if(parse_orig_ruri(msg)< 0) {
+		LM_ERR("bad request or missing RURI\n");
+                return -1;
+	}
+
should be:

+	if(parse_sip_msg_uri(msg)< 0) {
+		LM_ERR("bad request or missing RURI\n");
+                return -1;
+	}
+
and instead of:


+		&(msg->first_line.u.request.uri) );
should be 

+		GET_RURI(msg) );

This ensures that latest R-URI value is taken -- you used to get original r-uri.

If someone can test and report, I will commit quickly.

Cheers,
Daniel

OK, it turns out that the presence application is properly updating
subscriptions within a dialog, and creating new subscriptions outside
a dialog.

The difficultly is that I am rewriting the To: header, since I used
dirty tools, it was dropping ;tag=, so the server thought it was a new
dialog and the phone the same dialog.
      
This should be fixed once r-uri is used instead of To header, right? I
am trying to find some time to fix it, maybe with a mod param option.

Cheers,

Hi Daniel,

Some time ago we posted a patch to try to accomplish what you mention:
http://sip-router.org/tracker/index.php?do=details&task_id=18

Hope it helps.

Regards:
Francisco

  
    
I am testing to make sure that the issue is resolved.

David

Alright, I finally found the proper RFC,
http://www.rfc-editor.org/rfc/rfc4235.txt

Section 4.1 :

"version: This attribute allows the recipient of dialog
information  documents to properly order them. Versions start at 0,
and increment by one for each new document sent to a subscriber.
Versions are scoped within a subscription. Versions MUST be
representable using a non-negative 32 bit integer."

Versions are scoped within a subscription, so when a new
subscription is started, ( after the 1 hour expiry ), the version
should be reset as it is a new subscription and therefore a new
scope ?

When the subscription expires, is it renewed or is a new
subscription created? Is the scope separate, or is it the same
subscription updated?
            
I think this is another questionable thing about SIP. IMO, it is
same subscription if the dialog attributes do not change (call-id,
from tag and to tag). But others can argue is it a new subscription.
Anyone else on this one?

          
The proper RFC for generic subscription/notify questions is RFC 3265.

"3.1.1 Subscription Duration
SUBSCRIBE requests SHOULD contain an Expires header (defined in SIP
[2]). This expires value indicates
the duration of the subscription. In order to keep subscriptions
effective beyond the duration communicated
in the Expires header, subscribers need to refresh subscriptions on a
periodic basis using a new
SUBSCRIBE message on the same dialog as defined in SIP [2]"

This indicates to me that it's the same subscription as long as you
refresh it.

RFC4235 refers to RFC 3265 for general terminology about subscriptions.
