Maintenance Manual
Incoming Calls have no Caller ID Information on ISDN
Trunks
Issue

Actions
Caller ID and name information is not necessarily the same. Caller ID is the number designated to be
displayed and name is text information to be displayed. In most regions, both of these features must be
purchased from the Central Office/Network Provider before they become available to users.

Central Office/Network Provider. In some countries, the caller ID feature must be purchased from
the Central Office/Network Provider before it is activated.

from the Central Office/Network Provider. In some countries, this feature must be purchased from
