- The purpose of Call Parking is to put a call on hold and resume the call from another extension.
- Legacy Phone systems used to have what were called Square Line
Appearances aka Shared Line Appearances. The point of Square Line
Appearances was to assign POTS lines to DSS/programmable keys on a
phone. If the POTS line received a call the DSS key would blink to show
Ringing and the phone would ring for an audible warning. All phones in
such an environment would have the same Line Appearances appearing but
not necessarily ringing on their DSS keys. If by example extension 221
answered a call on Line 1 and wanted another extension to pick it up
they would press the hold button on their phone and tell another
extension to press the blinking held line on their phone to retrieve the
call. This pre-dates transfer and was never considered a function of a
PBX. PBX’s typically use Trunks like ISDN PRI services or in today’s
technology use SIP Trunks. These trunks have no concept of Lines in the
way that old POTS lines worked. Call Parking was invented to place a
call on hold and resume the call somewhere else without having to
transfer the caller to another extension.
- Reserved Parking in an advanced way to Park calls which is
especially useful to break up Call Parking configurations into
departments. With Reserved Parking each department gets their own Call
Park extension and Parking Lots.
If after configuring Reserved Parking you cannot pick up the Parked call using the BLF button then restart the Realtime Service.
