On TD26 - Fast TCS and M/S negotiation in H.323v4

Srini,

This only applies to a Facility message carrying an H.450.1 Supplementary
Service APDU, not to Facility messages in general. For example, H.323 does
not impose this constraint on Facility/reason=startH245. If an incoming
Setup message does not contain an H.245 transport address and does not
indicate support for H.245 Tunneling, we immediately send
Facility/reason=startH245, even before we send Alerting. This is allowed,
and the recipient of this Facility is required to connect on our H.245
transport address.

Pete,

It was specified in section 6.3 of H.450.1 specification

-       a FACILITY message shall not be sent if a SETUP message
previously
sent or received has not been answered.
