Using pick-up you can take a call on your own phone that was originally sent to another internal telephone or to an own voice mailbox.

If the user is authorised to accept global calls, this applies to calls to all other users.

As an alternative, the authorisation for group calls and voice mailboxes can be configured. Here, the user is authorised to take calls from users that belong to his group. Furthermore, the user with this option is authorised to take over calls from those voice mailboxes of which he is the owner.

Using this function, a member of this group can pick up calls to the phone number of the group as well as direct calls to individual members of the group.

Using for example a function key, not only calls to the phone number of the group, but also calls directly to the user phone number of a group member will be signalled on the phone to the group member.

The preliminary pick-up query function enables the display of the calling numbers even before a pick-up is carried out. The PBX supports the SIP function BLF (in accordance with RFC 4235) for this purpose. BLF allows VoIP end devices to monitor other internal phone numbers and receive information about their calls.

The display of call numbers on an incoming call or during a call is unlike the other information protected by the preliminary pick-up query and monitoring setting for users and groups.

If a call has already been taken, a call already in progress can be accepted and thus taken over in the same way as with pick-up. To prevent accidental take-over, this function is protected by a user setting and can be switched on, e.g. for answering machines.
