Not generally. > 2. When a UAC sends his REGISTER request who can NOTIFY his presence ? When a proxy server which implements a event registration package i.e., (RFC 3680) receives a REGISTER message, it sends the NOTIFY. Normally, a presence server which aggregates information from multiple sources will SUBSCRIBE to the proxy server to get notification about registration state changes. > > 3.

The presence server received NOTIFY (event=reg) from registrar/proxy and then generate NOTIFY ( event = presence) to all the watchers of the user. > > I took a look at resiprocate/presSrv source files but seems to be > incomplete, isn't it ? yes, thats true. > > best regards > > massimo guadagnoli > _______________________________________________ > Sip-implementors mailing list > [email protected] > https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors -- Not everything that can be counted counts, and not everything that counts can be counted. -By Albert Einstein _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
