Romeo ho hauria tingut molt més fàcil...

The following example shows Juliet with several IM clients where she
can be reached. Each of these has a unique SIP contact and MSRP
session. The example takes advantage of SIP's capability to "fork"
an invitation to several contacts in parallel, in sequence, or in
combination. Juliet has registered from her chamber, the balcony,
her PDA, and as a last resort, you can leave a message with her
nurse. [...]

When Romeo opens his IM program, he selects Juliet and types the
message "art thou hither?" (instead of "you there?"). His client
sends a SIP invitation to sip:juliet@thecapulets.example.com. The
proxy there tries first the balcony and the chamber simultaneously.
A client is running on each of those systems, both of which set up
early sessions of MSRP with Romeo's client. The client automatically
sends the message over MSRP to the two MSRP URIs involved. After a
delay of a several seconds with no reply or activity from Juliet, the
proxy cancels the invitation at her first two contacts, and forwards
the invitation on to Juliet's PDA. Since her father is talking to
her about her wedding, she selects "Do Not Disturb" on her PDA, which
sends a "Busy Here" response. The proxy then tries the nurse, who
answers and tells Romeo what is going on.


...si hagués utilitzat la missatgeria SIP.

PD: aquest és el post #100 de Telecopèsol! =) Friki, eh?
