ScopTEL Reserved Call Parking

  • 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.
