Methods, systems, and computer program products for dynamic blocking and unblocking of media over packet resources

A system for controlling media over packet resource allocation by a remote media gateway controller, the system comprising:

• (a) a first media gateway controller for controlling a first media over packet resource;
• and
• (b) a second media gateway controller for controlling a second media over packet resource, wherein the first media gateway controller is adapted to determine whether establishment of calls involving the second media over packet resource would violate a policy of the first media gateway controller, and, in response to determining that the establishment of calls involving the second media over packet resource would violate a policy of the first media gateway controller, sending a message from the first media gateway controller to the second media gateway controller for limiting the establishment of calls involving the second media over packet resource.

A computer program product comprising computer-executable instructions embodied in a computer-readable medium for performing steps comprising:

• (a) at a first media gateway controller configured to control a first media over packet resource, determining whether establishment of calls involving a second media over packet resource managed by a second media gateway controller would violate a policy of the first media gateway controller;
• and
• (b) in response to determining that the establishment of calls involving the second media over packet resource would violate a policy of the first media gateway controller, sending a message from the first media gateway controller to the second media gateway controller for limiting the establishment of calls involving the second media over packet resource.
