Abstract

The invention relates to method and apparatus by which the order in which ISDN terminals answer incoming calls can be easily established and changed by the ISDN user. The order is established by assigning a waiting time to each terminal, this waiting time being determined, e.g., by the subscriber number of an incoming caller or the type of call. A terminal only signals its eligibility to accept an incoming call after the waiting time has elapsed and its compatibility with the call has been established.
