Abstract
In a method and apparatus for signaling a voice over Internet protocol (VoIP) call based on a class of service in a VoIP service system, a database which includes VoIP signaling information differentiated by the class of VoIP service is built, and the database is retrieved by a service class assignment condition to produce a call setup message. The call setup message includes information related to the service class. Accordingly, it is possible to perform dynamic VoIP signaling by setting a differentiated service class based on each user or a primary factor of each class of the VoIP service.
