3.1.5.2.2.2 Receiving an Interface Release Message

Upon receipt of an Interface Release message, the InterfaceId contained in the packet MUST be disabled. Any other packets that contain the released InterfaceId SHOULD be treated as failure cases and SHOULD result in termination of the connection. After being released, interface IDs MAY be reused by other calls that pass interface IDs. This message is one-way only and does not require sending a reply. Releasing an interface MUST NOT generate an error code.
