Dear Paul,

Thank you for your reply, and your correction on the new h.246
annex-e. I expect to see some interesting contributions coming
your way.

You also,  pointed out a every informative item.

Maybe the suggestion on expanding our H.323
interworking to provide  PSTN services and H.323
terminal support on a Class-5 switch
has merit. But replacing a ISDN terminal or PC with
a modem connection to Internet, with a H.323
IP/Class-5  gateway is deja vu.

If you have more information could you please share
that information with us. Which are the groups working
on providing H.323 terminals on Class 5 Switches.

Regards,
Ed

So far new parameters in H.225.0 RAS messages, we may also need to
to add parameters to H.225.0 (q.931) call control.
