Some more corrections:
The needResponse field in IRR should be OPTIONAL. The reason is that
the field is completely irrelevant to IRR that is a response to IRQ. We

Thanks for the note.
In addition, I have the following corrections:
TimeToLive should be INTEGER(1..4294967295) instead of 4294967296.
With the addition in V2 of supplementary services, fast call setup, and
other items, the length of the User-user IE specified in the tables for
each of the various Q.931 messages should be extended from 2-131 to
something larger (any suggestions?).
The callReferenceValue definition (at least in ARQ) should be modified
to remove the statement that the CRV comes from the Q.931 message.
If you find other needed corrections, please let me know.
