Paul,

First, a non-v4 endpoint would not reply to a v4 feature of early H.245
tunnel, so it cannot be lost.

Second, a lost message in a GK is not good; and will result in a failure to
establish the early H.245.

I would still like to see this as a v4 mandatory.  For then there is a
possibility to have migration in support of early network features.

Bob,

...and what if the EP is in communication with a pre-v4 EP or GK?.

Paul,

An additional consideration on this subject:

In order to have a working early H.245 tunnel, I would like to make CALL
PROCeeding and PROGRESS messages as mandatory understood when received in
v4.  Otherwise, the user will be forced to use a FACILITY message along with
these messages which will increase the used bandwidth.

Bob
