Hi Benny and all, One question need your confirm regarding the optional id parameter of event package header Per the sec. 3.1.2. "Identification of Subscribed Events and Event Classes" in RFC 3265 pp7 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. Also, in pp8 of RFC3265 says.. A SUBSCRIBE request MAY include an "id" parameter in its "Event" header to allow differentiation between multiple subscriptions in the same dialog. I can find the "id parameter" definition in \pjsip-simple\Evsub_msg.h However it seems that PJSIP does not implement the feature mentioned aboce (multiple subscriptions in the same dialog. ) Am I right? Thanks for your answer in advance! _________________________________________________________________ 輕鬆分享 – 利用 Windows Live 相簿分享相片 http://download.live.com/toolbar

But if we're receiving SUSBCRIBE with id set, we should be able to respond correctly. I haven't tried with doing multiple subscriptions with one dialog. Though it should work, what for? cheers Benny > > Thanks for your answer in advance! > > ------------------------------ > 聰明搜尋和瀏覽網路的免費工具列 — Windows Live 工具列 <http://download.live.com/toolbar> > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip@lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org > >
