Handover during a call from a PP
If the PP user is moving and the PP detects a stronger signal from another RFP, it starts the
handover process.
Upon completion of the handover process, the voice path between the IP phone and the PP is
established:
• Between the IP phone and the primary RFP
• Between the primary RFP and the secondary RFP.
The following figure illustrates this scenario:
