2.Arrangement with the carrier at the time of provisioning is needed.

Event Based CCIS

This feature allows a PBX customer that does not have a tie line (or when a customer cannot use the tie line due to the busy or fault of the line), to use the various CCIS feature by using the ISDN line as a CCIS virtual tie line, on the 2400 IPX - 2000 IPS connection or the 2000 IPS - 2000 IPS connection.

6.Billing information of the virtual tie line using the ISDN line is treated as regular tie line calls.

7.Billing information of the virtual tie line using the ISDN line is treated on tandem calls.
