Re: [OpenSER-Users] uaCSTA support in openser

well on the microsoft side we have the two main scenarios which interact not only in MS environment: - one is the softphone integration, where office communicator acts as single user agent (having its own phonenumber). in this case all the SIP traffic is routed to this OCS mediation server to communicate with the 'outer' (non-MS) world using the OCS mediation server as gateway. - the other scenario is CTI, which means one phonenumber can either be routed to your office communicator client or to any hardphone connected to your pbx (which is in my case *). this has also the effect, that if for example i setup a call on my mobile the office communicator is informed about that to indicate in its presence indications, that i'm in a call. or for example you wanna setup a call by just clicking on one of your outlook contacts (click-to-call) but you want to use your deskphone (e.g. you wanna use your deskphone-headset). this just clicking on your outlook contact triggers an INVITE event letting your deskphone ring. when you pick up the receiver the call is issued to your callee. in this second scenario the SIP/CSTA traffic coming from OCS is not routed to the OCS mediation server but to a kind of external server which controls the telephony integration something like the siemens TCL (telephony control link) server. my goal is now to establish this telephony link to *. but as * doesn't understand SIP/CSTA, i thought of a box (e.g. my openSER box) which can do this uaCSTA to SIP translation. cheers -hugo -----Original Message----- From: Juha Heinanen [mailto:jh@tutpro.com] Sent: Friday, April 18, 2008 10:11 AM To: Hugo Koblmueller Cc: users(a)lists.openser.org Subject: RE: [OpenSER-Users] uaCSTA support in openser Hugo Koblmueller writes: understands > uaCSTA (aka.
