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.
