With the constant increase in number of voice over packet network users, quality of service becomes crucial for the success of this type of real-time applications. One of the quality of service techniques plays an important role: a decision process that takes place in voice gateways and is responsible of allowing calls only when expected level of performance in the network can be assured. In this paper we give comparison between two types of call admission control mechanisms, and suggestion when to use which type.
