Avoiding malfunctions in media gateway controllers and/or media gateways

A system including a media gateway communicatively coupled to a media gateway controller, the media gateway configured to:

• execute a first command from the media gateway controller;
• change the coding of at least one of a plurality of load data connection section terminations at the media gateway based on the first command;
• establish, based on one or more additional signaled commands received by the media gateway, if the media gateway has available all current commands to be executed for changing the codings in the terminations;
• and
• if all of the current commands are available, check for the connectibility of the terminations having the changed coding.

A device comprising:

• a first media gateway having a plurality of load data section connection terminations, wherein subsets of the terminations are associated with at least one context;
• a second media gateway;
• and
• a media gateway controller to control the media gateways;
• wherein the media gateway controller controls the first media gateway by sending a plurality of control signals to the first media gateway to change a coding of at least one of the plurality of the terminations;
• wherein based on the plurality of control signals, the media gateway determines if all of the plurality of control signals related to the terminations in the associated context have been received;
• and
• wherein when the media gateway determines that it has received all of the control signals related to the context, the media gateway changes the coding of the at least one termination.
