A signaling message consists of a collection of metadata as the message header fields and a payload (or content) as the message body. A message header field consists of a collection of message header fields. A message header field is a name-value pair and is represented by an IUccSignalingHeaderField object. The message body is represented by a string. The value of a header field field can be further divided into a set of header field field parameters. A message can be either a request or a response. This interface can be queried from IUccSignalingRequest or IUccSignalingResponse.
