Interesting proposal. Let me some questions: 1) - Alice has two active resources (alice-1and alice-2). - alice-1 uploads a new vCard. How is alice-2 notified about that change if there is no possibility of subscription to the vcard? 2) IMHO avatar should be part of the vCard (as vCard already includes photo and so): - Alice is subscribed to Bob's presence (just presence). - Alice retrieves the vCard (including avatar) of Bob. But there is no subscription as you said. - Bob uploads a new version of his vCard with a new photo. How is Alice being notified about the change to display the new avatar? 3) Where is the limit to say "this info requires subscription but this one not"? -- Iñaki Baz Castillo <[email protected]> _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list [email protected] http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
