Hunt Group Pickup name display

[SPIPOffice]

On V2.1(27), when you try and do *30 to pickup calls in a group, it does not display the group name on either on the phones (DT or Analoge)and does not show in phone manager, it just display ??.

Is this a know issue? one of the 1.4 version had this problems, 2.0 fixed this issus, now it appeared again.

Does anybody know if any of the earlier 2.1 had this issus.

Thanks.
