Submitted by Mikhail Zabaluev

Description
In some SIP deployments, a commonly contacted remote endpoint exhibits incompatible behavior if certain RTP payload numbers are in use. As some of those endpoints come from a major hardware manufacturer, and used in certain large corporate deployments, it's worthwhile to have a media channel interface defining a property to blacklist codec IDs from being assigned by the stream engine.
The type could be a(uau) or a{uau}, where the first u is Media_Stream_Type and the second u is for codec ID numbers.
