Lets suppose that 3 parties A,B and C are in a conf. call managed by a central server . Now, A wants to request that D be invited into the conf. However, D is an older client and does not support REFER. Thus, A sends a REFER to the conference server asking it to INVITE D.
The conf. server however needs D to authenticate itself to the server before it allows D to get in. To me this is not mutual-authentication as addressed by authenticate-info (at least my understanding of it). It is possible that this is the first message exchange that has occurred b/w the server and D and there is no prev. request that was correctly validated using digest. Here, the conf. server wants to basically tell D that ' I have been asked to invite you, but you must authenticate your self against me'. What is the correct procedure to do this ? (assuming that the server _must_ be the one doing an INVITE to D and not the other way around, ofcourse) -- Arjun Roychowdhury @ Hughes Software Systems 11717 Exploration Lane, Germantown MD 20876 (O): 301-212-7860 (M): 240-475-2139 _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
