Thinking that the "extension" is a user, not a phone:
Admin: 1) Record is created with a 4 digit UserID 2) Context to use is stored against this UserID
User Login:
1) The user dials **1#, and enters their 4 digit UserID
2) * looks up a record from the database using the UserID as the key (with some graceful error handling)
3) * then stores the ${EXTEN} variable as a value against the UserID
Usage (for calls to the User):
1) When someone makes a call to the user, they dial the 4 digit UserID
2) * looks up a record from the database using the UserID as the key (with some graceful error handling)
3) * gets the current ${EXTEN} variable from the record
4) * dials the ${EXTEN}
Usage (for calls from the user):
1) User dials a number
2) * looks up a record from the database using the ${CALLERIDNUM} as the key (with some graceful error handling)
3) * gotos to the context defined by the admin
4) * makes the call as normal
User Logout:
1) User dials **1#0000#
2) * looks up a record from the database using the UserID as the key (with some graceful error handling)
3) * sets the "extension" to 0000 (and thus also indicating that the person is not available)
This allows anyone to call (for example 5711) and find me, no matter where I am
This allows for the "person" to be controlled by the dial plan, not the extension.
For example, the standard way of checking access permissions is by the context (SIP/5711 is allowed to dial local but not international). However, I could go to phone SIP/6712 (on my manager's desk) and call an international number). With the above method, your dial plan restrictions follow you.
It also allows for * to see if you are available or not - if not it can divert straight to voicemail.
Just a "straight out of my head" idea. Probably full of holes. I would appreciate any comments.

Subject: [Asterisk-Users] Extension "follow me"
We are going to have people in our office who do not sit at the same desk throughout the day (or week), and have Cisco 7940 phones using the SIP image.
Is it possible to easily set up the phone so that they can enter their
extension number and password on the phone, and thus have their extension
follow them ? I know that you can change the sip settings, but that requires
admin capabilities.
I know that this is similar to follow me, but person A might be at B's desk,
while B is at A's desk, so I can't use call forwarding, and I don't want to
ring x number of extensions in order to find the person.
I really want to "find the extension"
Julian.
