Handover is possiblewhen:a) The PS is on an intercom call or on a call with an outside party. (The call will not be disconnectedduring the handover.)b) A call is ringing at the PS. (The call will continue to ring after the handover.)c) The PS is in idle status (i.e., waiting to receive calls).[Example of Handover]Handover is not possible when the PS is:a) Not within range of another CS.b) Within range of another CS but that CS is busy.c) Screening a call via Live Call Screening (LCS) or recording a call via Two-way Record ( 1.19.2Voice Mail DPT (Digital) Integration)d) Paging other extensions.

If several PSs are members of an incoming call distribution (ICD) group, the availablechannels of a CS will become busy just by ringing each PS. Assigning a group of PSs to a PS ring groupalleviates this strain on the CS because only one channel is needed to ring a PS ring group's members.Call is not disconnectedHandoverCS-2CS-1 CS-2CS-1Moving
