For example, to set up a cross-context connection, a first subscriber (A) who knows the address of a second subscriber (B) in one context, transmits the known address to a directory controller (70). The directory controller (70) utilizes the known address as a source address and accesses a directory database to find out the personal identification number of the second subscriber. The personal identification number is then utilized by the directory controller (70) to access the linking database to determine the directory database wh…
