2023年8月29日 · MGCP uses TCP port 2428 and UDP port 2427. TCP port 2428 in MGCP is used to open a new socket with the Call Agent to determine if the connection can be established. Without this new socket, subsequent MGCP Messages cannot be exchanged. It is also used to Send/Receive Backhaul Messages between PRI Endpoints and the Call Agent it is registered to.

The Media Gateway Control Protocol (MGCP) is a telecommunication protocol for signaling and call control in hybrid voice over IP (VoIP) and traditional telecommunication systems. It implements the media gateway control protocol architecture for controlling media gateways connected to the public switched telephone network (PSTN). [ 1 ]

2012年12月4日 · mgcp [gw-port] Example: Router(config)# mgcp [gw-port] Initiates the MGCP daemon. The optional port number argument allows you to specify the UDP port over which the gateway receives messages from the call agent (the gateway MGCP port number).

The well known port for MGCP callagent traffic is 2727. Example traffic XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).

The Media Gateway Control Protocol (MGCP) is a signaling and call control communications protocol used in voice over IP (VoIP) telecommunication systems.

mgcp协议制定的主要目的在于将网关功能分解成负责媒体流处理的媒体网关（mg），以及掌控呼叫建立与控制的媒体网关控制器（mgc）两大部分。 同时MG在MGC的控制下，实现跨网域的多媒体电信业务。

MGCP使用TCP端口2428和UDP端口2427。 MGCP中的TCP端口2428用于打开呼叫代理的新套接字，以确定是否可以建立连接。 如果没有此新套接字，则无法交换后续MGCP消息。 它还用于在PRI终端与其注册到的呼叫代理之间发送/接收回传消息。 最后，TCP端口2428用于在主呼叫代理无响应时故障切换至备用呼叫代理。 MGCP中的UDP端口2427用于终端和呼叫代理之间交换的MGCP消息。 这是一个基本MGCP流的示例。 您可以在示例中看到，网关从此语音网关（终 …

Media Gateway Control Protocol or MGCP is a protocol used for controlling Voice over IP or VoIP calls by external call control elements known as media gateway controllers or MGCs or call agents. MGCP allows for the registration of remote Gateway resources such as FXO, FXS, PRI ISDN channels etc.

2015年6月5日 · mgcp \* to enable mgcp on the router using default port 2427. we can change the port by stating the "port no" beside mgcp command.

MGCP uses standard port 2427 on the media gateway and 2727 on-call the control application. This means when a call control sends a request to the media gateway destination MGCP port is 2427, and when the opposite, the destination MGCP port is 2727.
