[Sip-implementors] issue regarding SUBSCRIBE method

[Dror Shlomo]

Hi,   I have a question about the SUBSCRIBE method as described in rfc2365 and in draft-ietf-simple-presence-10.txt   From rfc3265:   3.1.2. Identification of Subscribed Events and Event Classes … The "Event" header MAY also contain an "id" parameter.    This "id" parameter, if present, contains an opaque token which    identifies the specific subscription within a dialog.    And also   3.1.4.1. Requesting a Subscription … A SUBSCRIBE request MAY include an "id" parameter in its "Event"    header to allow differentiation between multiple subscriptions in the    same dialog.   My question is:   Are multiple subscription in the same dialog allowed in a presence event package? If so, how do I create the first dialog (SUBSCRIBE? INVITE? BOTH?) And most importantly, can I subscribe with in the same dialog several times, each with a different From and To URIs? Is the example correct regarding the questions above and considered as multiple subscriptions with in the same dialog?   Example:     UAC                            UAS   ------------SUBSCRIBE -------à From: sip:bob; tag=123 To: sip:alice; Event: presence; id=1 Call-ID: [EMAIL PROTECTED]   ß---------200 OK -----------------   ------------SUBSCRIBE -------à From: sip:bob; tag=123 To: sip:john; tag=234 Event: presence; id=1 Call-ID: [EMAIL PROTECTED]   ß---------200 OK -----------------   ------------SUBSCRIBE -------à From: sip:sam; tag=123 To: sip:bob; tag=234 Event: presence; id=1 Call-ID: [EMAIL PROTECTED]   ß---------200 OK -----------------       Regards   Dror Shlomo Followap R&D Software Eng. +972 67 262 683, 067-262683
