The functions described below enable the PBX to be used with mobile telephones and also with other remote telephones.

One user can be temporarily or permanently assigned to up to five telephones. This then means that they can, for example, use a telephone that is configured at their office workplace, a telephone that is in their home office and mobile telephone at the same time.

The integration of DECT base stations and telephones enables mobility anywhere in the building.

Use the Call Through function to forward calls via the PBX while on the move. In this case, the person being called sees, for example, the company phone number instead of the mobile phone number.

Use the FMC function to configure a mobile telephone as the user's telephone, so it can be accessed on the mobile phone network at any time. On outgoing calls, FMC acts like Call Through except that FMC is user-specific. The called person does not receive the mobile number or the central company number but the number that is also transferred from the office phone of the user.

COMfortel SoftPhone and COMfortel SoftPhone Mobile transform a PC or a mobile telephone into a fully functioning office telephone.

There are a range of different forwarding functions available if staying accessible while on the move is your main concern.

Use the Call forwarding function to forward calls independently of the current situation (immediately, on busy or on no reply). Different call forwarding options are available, depending on whether calls are to be forwarded for a single user, for a group or for external numbers.

Use the Follow-me function to configure forwarding from the destination telephone.

The Multi-Path Call Forwarding function also signals incoming calls on another telephone, even an external telephone, although it does not forward the call.
