A switch device connectable to an ISDN, said switch device comprising:
- a first part which adds a calling ID information element to a first call setup message to be transferred over an ISDN tie line connecting said switch device to another switch device,
- said calling ID information element including identification information on a terminal which is connected to the ISDN and makes a call.
A switch device connectable to an ISDN, said switch device comprising:
- a first part which translates an extension number of an extension terminal connected to the switch device into a dial-in number;
- and
- a second part which adds the dial-in number to a first call setup message to be transferred over an ISDN tie line connecting said switch device to another switch device.
A system comprising:
- a first device and a second device which are connected to an ISDN,
- said first switch device comprising:
- a first part which adds a calling ID information element to a first call setup message to be transferred over an ISDN tie line connecting the first and second switch devices together,
- said calling ID information element including identification information on a terminal which is connected to the ISDN and makes a call.
