RE: [Sipping-tispan] Requirements -02h

["Michael Hammer \(mhammer\)" <[e-mail]>]

This appears to be a consequence of the multi-terminal status union,
meaning that some centralized entity (could be co-located with one
terminal) would need to keep track of the call state of all the
terminals representing that user (AoR).  If any one of those terminal is
busy, then the caller is busy.  Only when all terminals are unbusy, then
the caller is deemed free to participate in the call completion.

That assumes that only one human uses all the terminals.  If it is
possible for more than one person to use those terminals, there could be
a problem.  Picture the teenage daughter (son) yacking away while the
father (mother) is trying to use CCBS to complete an important call.
How one sets up the relationship from terminals to AoRs can be tricky.
Perhaps some indication of CCBS from this terminal only would be useful.

At least that is how I am interpreting the requirements.
