In reading H.323V4 (from APC-1874), I noticed in the procedures of section 10.4.3 (tunneling of a signalling protocol in H.225.0 call signalling messages) a reference to a tunnelledRequired flag, which doesn't exist.
Can the following change be made to H.323V4, or at least captured in the Implementers Guide (assuming this error has not already been corrected)?
Section 10.4.3, second paragraph:
If an endpoint will only allow the call to proceed if tunneling is supported, it shall set the tunnellingRequired flag in the Setup message; the tunnelledRequired tunnellingRequired flag shall not be included in any other message than Setup. If an endpoint receives a tunnelledSignallingMessage with the tunnellingRequired flag set in the Setup message and is not able to tunnel the protocol, it shall terminate the call by sending a Release Complete with a reason of tunnelledSignallingRejected; a tunnellingRequired flag in any other message than Setup shall be ignored.
