What is the difference between a gatekeeper and a gateway?
Gateway = pathway between two different networks. IE: A TDM->IP gateway allows you to bridge calls between the PSTN and an IP network. Gatekeeper = a device that controls access to a network.
What is the difference between voice gateway and cube?
A CUBE is primarily an IP-to-IP gateway that helps connect two or more similar or dissimilar networks, while offering a host of features that a regular voice gateway cannot offer. For example, a CUBE router can connect an H. 323 network to SIP network or vice-versa, or a SIP network to a SIP provider.
What is the gatekeeper function?
Gatekeepers are people or policies acting as a go-between, controlling access from one point to another. They may refuse, control or delay access to services. Alternatively, they may also be used to oversee how work is being done and whether it meets certain standards.
Why is it important that a H 323 gatekeeper manages the bandwidth of a LAN?
