| Description | The MGCP protocol is organized as set of transactions, each
of which is composed of a command and a resonse. The MGCP
messages, being carried over UDP, may be subject to losses.
In the absence of a timely response, commands are repeated.
The media gateway must keep in memory a list of the responses
that it sent to recent transactions, and a list of the
transactions that are currently being executed.
Recent is here defined by the value of cxeCcProfileThistTimeout
that specifies the number of seconds that responses to
old transactions must be kept for. |
