ISDN supplementary services supported
In the following overview ISDN supplementary services are categorized as follows:
• Identification services
• Connection services
• Rerouting services
• Call charge services
• Other services
As a rule network interfaces are wired as a point-to-point connection (P-P). How-
ever, the point-to-multipoint (P-MP) connection type is also possible. Not all ISDN
supplementary services are provided by network providers on both connection
types or supported by the communication server.
