Hot Desking allows local or remote (via SBC) connected IP Phones to be used by multiple users, one at a time. A device currently not used by a user can’t make outbound calls, unless the number is defined as an “Emergency Number”. This way the extension is also protected, with the PIN protection feature, from dialing to unmonitored locations.
To start using hot desking:
In order to log onto a hot desking device the user must dial *77*[Extension Number]* (e.g. *77*100*). The IVR service will answer the call and prompt the user to enter their voice mailbox PIN number. Upon completion a confirmation prompt is played and the device is reprovisioned.
Info: If the user hears “file not found” instead of the login prompt you MUST update the prompt set of your system in Settings → System Prompt and update all installed but marked as outdated prompts.
In order to logout from a device the user just needs to press the first available BLF button on the device which is reserved on all hot desking devices to logout. If a user has configured BLF settings in their extension, they will be shifted by one BLF button down in order to accommodate the logout button.
Alternatively on a device without BLF button s the user shall dial *77*5*.
It is possible to roam directly from one extension to the next without logging out in between. While user A is currently on a device just reuse the login process to directly log in to the next extension.
The current status of a device can be determined in two ways. All hot desking devi c es use an extension name with HDXXXX. If this is shown in the display of the device - then the device is idle. Once a user log s in to the device via hot desking, the device will show the user's extension number.
For administrators the hot desking tab will show which users are currently logged into which devices and which devices are idle. The administrator has the option to force a user to logout remotely by selecting the HDXXXXXX extension and pressing the “ Logout” button from the management console .
While using a device provisioned in hot desking mode, no custom template can be used. CTI is only tested and supported while using the 3CX web client. CTI in hot desking via the 3CX client is not supported and therefore cannot to be used.
In case the call gets directly disconnected at the login process *77*[EXT]*, with the message “forbidden”, review the configured dial codes (Settings → Dial Codes) of the system and ensure that no other dial code starts with *7.
