What are the main advantages of using the gatekeeper?

Security and control over the VOIP network are the biggest advantages to using a Gatekeeper. Only MultiVOIPs that are registered to the Gatekeeper will be allowed to place or receive calls. The Gatekeeper also gives you the ability to monitor and manage the activity of registered MultiVOIPs. You can set policies and control network resources, such as bandwidth usage, to help ensure optimal performance of your MultiVOIP network. The gatekeeper does not provide QOS on a network, only a routing device can perform QOS services.
