All users logged in to the group will ring simultaneously. Selected users will start to ring after the configured delay time (after:). If a call was not accepted, although all logged-in members of the group were called, the call would be finished with a busy signal.

The call is handled almost similar to the call strategy All. The only difference is the way multiple calls to the group are handled: If the group receives further calls during an active call, the group will be split into several smaller groups ringing for a specific active call. But there will never ring more calls in the group than the number of free available group members. Additional calls will then be rejected with a busy. If a call is accepted, the other phones ringing so far for this call are assigned to the other pending calls and will immediately start to ring again. If a group member finishes a call, this user will immediately ring again for the pending calls. The timer for the configured delay time (after:) starts after receiving the first call to the group and will not restart for additional incoming calls.

Only the phone of one group member will ring. After the configured delay time (after:) another single group member will be called. The order of calls depends on the configured Priority. If a call was not accepted, although all logged-in members of the group were called, the call would be finished with a busy signal.

Only the phone of one group member will ring. After the configured delay time (after:) another single group member will be called. The order of calls depends on the configured Priority: The first logged-in group member gets the position 1 in the order of calls, the second one position 2, ... . If position 1 takes a call, the second call will be assigned to position 2. The member of the group with the position 1 will get the last position in the order for a future call after he has finished the current call. If a call was not accepted, although all logged-in members of the group were called, the call would be finished with a busy signal.

Only the phone of one group member will ring. After the configured delay time (after:) another single group member will be called. If all members of a group are called, the process will be restarted with the first member of the group of the call order. In the first rotation the next member of the group of the call order will be called immediately if a user is busy. In the second rotation the busy users will hear knocking (only from external). The order of calls depends on the configured Priority.

Here initially only one group members' phone is ringing. After the configured delay time (after:) another single group member will be called. If the group receives another call B, initially the free group members will ring one after the other (adding). If for the first call A less than half of the group members are ringing, more members are added to this call until exactly the half is reached. If for the first call A more than half of the users are ringing, no members are added to this call (frozen). Only the remaining users are added to call B. If all group members are already ringing for call A, the group is split for the calls. The order of calls depends on the configured Priority. If a call was not accepted, although all logged-in members of the group were called, the call would be finished with a busy signal.
