Mobile Extension: Allmänt
  • CS1000 Mobile Extension funktionen ger möjlighet att ansluta mobiltelefoner som fungerar som anknytningar i växeln.
  • Inkommande samtal kopplas automatiskt ut till mobiltelefon som är kopplad till anknytningsnummer som rings. Samtal från mobiltelefon rings med samma typ av nummerplan som används inom växeln i övrigt.
  • Samtalskontroll som används för annan fast anknytning gäller på samma sätt för mobiltelefonen.
  • Mobila användare konfigureras med en Universal Extension (UEXT) vilket är den logiska/virtuella kopplingen till användarens mobiltelefon.
  • En Mobil-användare kan också ha en bordstelefon (digital, IP etc) som komplement till Universal Extension. Detta är inte obligatoriskt utan är en möjlighet.
