Feature request: redirect incoming call.

[Gerald Maguire]

Consider the following scenario:

The user comes into the business center in the morning and chooses
cubicle A47, they pull out their PDA/phone/... and browse to the
business center web page and choose "Currnet Location", they get a
menu which is customized to the local site (since the system already
knows they are at the business center based upon the IP address {or
other data}), they either select A47 from a menu or enter it. This
does several things:
1. it reserves the cubicle/room/... for them
2. it enters the charges for using this cubicle/room/... {to allow
   chargebacks to the user's facilities account}
3. it puts an entry in the SIP proxy for:
   a. the user's current wireless device
   b. the SIP devices in this cubicle/room/...
      {this can include a desk phone attached to the PBX, an IP phone,
       speakers, data projector,  ... }

Now when there is an incoming call for this user - the system can fork
the INVITE and the user's PDA/cellphone/... desk phone ... rings and
the user answers which ever they want to use - the SIP proxy
terminates the rining on all the other devices.

When the user leaves they either explicitly update the
booking/registration system or their reservation times out.

The same can be used when a physical customer meeting occurs and the
user goes to the business center's conference room - where they simply
do another web based registration.

As noted in my earlier mail this can all be done independently of the
SIP UA or devices which are used. So while it could be built into
minisip, why do so?
