To begin with you are going to need to be running on version 4 with the addition of advanced networking licenses to enable you to login from any location.
See this for more info on scenarios;
Logging in and out at a phone can be done either using IP Office short codes or programmable buttons.
The default system short code for logging in, is *35*N# where the user replaces N with their extension number and then login code separated by a *. This uses the short code feature ExtnLogin. If the user dials just a login code as N, it is checked against the user with the same extension number as the extension's base extension number.
The default system short code for logging out is *36. This uses the short code feature ExtLogout.
The ExtnLogin and ExtnLogout features can be assigned to programmable buttons on suitable Avaya phones. The ExtnLogin button will then prompt the user to enter their details.
Agents and Call Center Operation (CCC and CBC)
On IP Office systems with a call center application such as Compact Contact Center (CCC) or Compact Business Center (CBC), logging in and logging off is a key part of tracking and reporting on agent availability. It also controls call distribution as, until the agent logs in, their hunt group membership is seen as disabled. To be treated as an agent, the user must be set to Forced Login. See Scenario 4 below.
Scenario 1: Occasional Hot Desking
In this scenario, a particular user, for this example extension 204, needs to occasionally work at other locations within the building.
A Login Code is added to the user's configuration settings, for this example 1234.
The user can now log in when needed at any other phone by dialing *35*204*1234#. The phone's default associated user is logged off by this and their calls get busy treatment. User 204 is also logged off their normal phone and their calls now rerouted to the phone at which they have logged on.
When finished, the user can dial *36 to log off.
This logs the phone's normal default user back on. Its also logs the hot desking user back on at their normal extension.
Scenario 2: Regular Hot Desking
This scenario is very similar to the one above. However the user doesn't want to be automatically logged back in on their normal phone until they return to its location.
A Login Code is added to the user's configuration settings, for this example 1234.
The Forced Login option is selected.
When the user logs out of the phone that they are currently using, they are no longer automatically logged in on their normal extension. When they return to it they must dial *35*204*1234# to log in.
Whilst not logged in anywhere, calls to the user receive busy treatment.
Scenario 3: Full Hot Desking
Similar to the scenarios above but this time the user doesn't have a regular phone extension that they use. In order to make and receive calls they must find a phone at which they can log in.
The user is given an Extension directory number that is not matched by the extension directory number setting of any existing extension.
They are also given a Login Code and a Login Idle Period is set, for this example 3600 seconds (an hour). Forced Login isn't required as the user has no default extension at which they might be automatically logged in by the IP Office system.
The user can now log in at any available phone when needed.
If at the end of the business day they forget to log off, the Login Idle Period will eventually log them off automatically.
Scenario 4: Call Center Hot Desking
In this scenario, the phone extensions have no default extension number. Several phones set like this might be used in a call center where the agents use whichever desk is available at the start of their shift. Alternatively a set of desks with such phones might be provided for staff that are normally on the road but occasionally return to the office and need a temporary desk area to complete paper work.
For the extensions, the Extension setting is left blank. This means that those phones will be associated with the NoUser user's settings and display NOT LOGGED ON.
The call center agents or road-warrior users are configured with Extension directory numbers that also don't match any existing physical extensions. They are all given Login Code numbers.
The users can log in at any of the extensions when required. When they log off or log in elsewhere, the extensions return to the NoUser setting.
