The functions described below help people work together.

The Groups function is used to assign individual users to different teams or departments and to control their availability, among other things, by logging them in or out.

Different call strategies can be used to assign inbound calls to group members "properly".

The Announcement before answering text greets callers to a group with an announcement. If the line is busy, callers are placed directly in a waiting loop.

Use the Busy on Busy function to specify the maximum number of connections after which group members can no longer be contacted.

If a group of users is to be able to have an external call at any time, call channels can be reserved for this group.

The SIP BLF and presence functions display which team members are busy or present.

When the PBX Call Assist CTI software application is installed on the PBX, users can see which team members are present, use video-telephony and share screens and files.

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 Pick up all calls to group members function is enabled, one member of the group can not only pick up calls to the group's phone number but also direct calls to individual group members.

The Enquiry prior to pick-up function enables users to see which call they want to receive before they pick it up.

If a caller wants to speak to a specific colleague, their call can be transferred directly to their requested call partner. If necessary, the caller can also be announced by a query call.

By displaying the busy and presence status, you can look at the telephone display, before you transfer the call, to find out which colleague is free to take the call.

The open query call can be used to place callers who are to be transferred in a park position so that the requested call partner can take the call on a different internal telephone.
