Hello Francisco,
somehow I missed that patch, thanks for reminder! Is it against sip-router or kamailio 1.5.x?
I'm a Francisco's workmate. The patch is against kamailio 1.5. We have been using this patch in our test environment for a couple of months without problems.
BTW, we have noticed that in the dialog-info+xml body the <target uri="..."> is set to the same value as the <identity> for both local and remote elements. Is this correct? or should they be set to the local and remote contact instead?
Best regards,
Santi
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.

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.
