Which statement represents the definition of an MGCP endpoint?
A.
The interconnection between packet and traditional telephone networks.
B.
Any analog telephony device (PBX, switch,ect).
C.
IP hones
D.
The gatekeepers in aVoIPnetwork.
Explanation:
A typical MGCP gateway environment connects on one side with a public switched telephone network (PSTN), and on the other side with an IP network.Specializedcall agentapplications control the flow of media data across the distributed environment.Call agents determine the route that data follows as it flows through the system. Multiple call agents can control call processing and data transfer. These call agents use a separate protocol to synchronize with each other and to send coherent commands to modules under their control.
MGCP assumes a connection model where the basic constructs are endpoints and connections.Endpoints are sources or sinks of data and could be physical or virtual. Examples of physical endpoints are:
* An interface on a gateway that terminates a trunk connected to a PSTN switch (e.g., Class 5, Class 4, etc.). A gateway that terminates trunks is called a trunk gateway.
* An interface on a gateway that terminates analog POTS connection to a phone, key system, PBX, etc. A gateway that terminates residential POTS lines (to phones) is called a residential gateway.
An example of a virtual endpoint is an audio source in an audio- content server. Creation of physical endpoints requires hardware installation, while creation of virtual endpoints can be done by software.
