Based on the feature “Mobile HFA Logon“,the functionality “Shared Desk Area“ can be used. The Shared Desk Area is a scenario, that allows a dynamic assignment of telephone devices to users. At a switch a number of users without fix phones, and phones with virtual subscribers are configured. The phones are spread over various rooms or buildings. The number of phones might be significantly lower than the number of users.

The real users can use any phone of the Desk Area. One terminal can be used by different users one after another.

E.g. user Jones can use a phone starting at 9.00 am. User Jeffrey can use the same phone afterwards when Jones has left the office. Both users can use the same phone using their own user characteristics.

User Jones comes to a phone and logs on with own phone number and password. If the logon succeeds he can phone as “Jones“.

His session is canceled if he logs off or if another user (Jeffrey) logs on to this phone.

After a logoff the phone comes up as configured. For this reason any physical phone must be configured with a virtual subscriber number (Dummy Number).

If a user logs off or his session is canceled by another user logging on at the device this user turns into visited state. That is that any call to him is redirected to the system CFNR destination.

In the following example phone numbers starting with “3” indicate users of the shared desk areas configured at the switch. The dummies for the telephones have “names” like “office1 desk12” and corresponding numbers starting with “2”: 20112 (=office1, desk 12).

Now user Jeffrey logs on at desk phone 11 (knocks out Wilson). Jones logs off and moves to desk 12 for logon.
