Connection

Connections are created on each endpoint by an MG during call setup. A typical VoIP call involves two connections. A complex call, for example a three-party call or conference call, might require more connections. The media gateway controller (MGC) can instruct media gateways to create, modify, delete and audit a connection.

A connection is identified by its connection ID which is created by the MG when it is requested to create a connection. Connection ID is presented as a hexadecimal string, and its maximum length is 32 characters
