Re: [Kamailio-Users] Presence_Dialoginfo versioning

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?

Thanks, David kamailio.org(a)spam.lublink.net wrote: for the version number, which it retains to detect message loss)," after it resends a SUBSCRIPTION ? include a version number that increases by exactly one for each NOTIFY transaction in a subscription." renewal of ths subscription... version attribute. The server is counting the versions using the latest subscription as a reference point, and the phone is counting the versions from the first subscription ( at reboot ). the first after the last subscription? If it's version 1, it could confuse the phone cause a notification that is sent at the same time as the notification would have a confusing version. would it not logically follow that the different subscriptions for the same device have seperate versioning? 3 last version:135 version number had run up to 136, the lights started flashing again. unclear? _______________________________________________ Kamailio (OpenSER) - Users mailing list Users(a)lists.kamailio.org http://lists.kamailio.org/cgi-bin/mailman/listinfo/users http://lists.openser-project.org/cgi-bin/mailman/listinfo/users
