EAG Gateway Series Administration Guidelines   

MAG-06007 Rev. A 

 

 

Figure 17. MGCP Settings Interface 

 

MGCP Port 

In the MGCP Port field enter EAG’s gateway MGCP port number. Factory default is 2427. You can use 

any port number as long as it does not conflict with another port number. 

Call Agent 

In the Call Agent

7

 field enter the call agent address and port number. Address and port number should 

be separated by a colon. Address could be IP address or domain name. If you use domain name, you 

should invoke DNS service and set parameter of DNS server in the System Settings page. A complete 

sample configuration is like this: 202.202.2.202:2727; callagent.com:2727. 

Domain Name 

In the Domain Name field enter the internet address or the IP address of the gateway. Examples: 

test.sunshinemind.com; [192.168.2.100] (if using IP address, [ ] signs can not be omitted).

 C Call Agent, also known as Media Gateway Controller, controls the Media Gateway. In MGCP, a call agent 

primarily handles all the call processing by linking with the IP network through constant communications with 
an IP signaling device, for example an SIP Server or an H.323 gatekeeper. 
Call Agent is comprised of the call control "intelligence" and a media gateway boasting the media functions, for 
example conversion from TDM voice to Voice over IP. 
 
Media Gateways feature endpoints for the Call Agent to create and manage media sessions with other 
multimedia endpoints. Endpoints are sources and/or sinks of data that can be physical or virtual. For creating 
physical endpoints, hardware installation is needed while virtual endpoint can be created using available 
software. 
 
Call Agents come with the capability of creating new connections, or modify an existing connection. Generally, 
a media gateway is a network element which provides conversion between the data packets carried over the 
Internet or other packet networks and the voice signals carried by telephone lines. The Call Agent provides 
instructions to the endpoints to check for any events and - if there is any - create signals. The endpoints are 
designed in such a way as to automatically communicate changes in service state to the Call Agent. The Call 
Agent can audit endpoints and the connections on endpoints.
