Restrictions:

• A call pickup group may not have more than 255 members (users + remote links).
• A group may have up to 255 Digits, but you should note that we do not recommend full signaling (SIGNAL=ALL) if there are more than 25 Digits. The default in this case is SIGNAL=LED and the default when there are more than 75 Digits is SIGNAL=NONE. You can correct this setting for the particular case.
• You cannot configure more than 1000 call pickup groups. Select and query the current value in the dimensioning (parameter PUGR). If you enter a group number during the configuration, it must be smaller than the PUGR value.
• A user may belong to only one call pickup group.
• The users in a call pickup group may not be silent monitors.
• You may not enter special users in a call pickup group.
• Users in a secretary system may not be in a call pickup group.
• A call pickup group must have at least 1 user. Therefore a group with only a remote link is not allowed.
• The alerting call (NOTRNG) only applies to digital station devices.
• If there are more than 75 stations configured in a pick up group with parameter GRPCAL in AMO COSSU, then the calls will not be signalled (no ringing and no display).
• Display update at pickup group members not possible after transfer
  A calls B, B answers and consults to C. C belongs to a pick-up group and the AUN digite members get on the display the notification about B calling C. If B now invokes a transfer, C will have A on the display as caller, but the pick-up group members still see that B is calling C.
• Pickup Group and Hunt Group with parallel ringing
  Only private calls to the hunt group members are signaled on all pickup group members. Calls to the master of a hunt group with parallel ringing are not signaled on other pickup group members
