It is neither possible, nor necessary, to come up with an error code
for all possible error situations that might occur. Consequently,
some error codes in the MGCP Protocol (RFC 3435) are indications of
very specific errors, whereas others are more generic in nature. In
general, the choice of which error code to use in a given error
situation may not always be clear. However, Call Agents may take very
different action depending on which error code is being used. The
objective is thus, to make sure that Call Agents behave the same for
a given error situation that occurs in a Media Gateway. This document
enables this by categorizing error codes based on expected Call Agent
behavior. It also expands on the descriptions of the error codes in
RFC 3435, giving additional guidelines for usage. The purpose is to
improve interoperability between Call Agents and Gateways.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
