In this use case, the calling endpoint is T.38 equipped and the called endpoint is not (supports T.30 only); in addition, the calling endpoint is properly configured to not initiate T.38 re-INVITEs itself, but relies on the receiving gateway (Asterisk+T.38 Gateway) to do so.

In this use case, the calling endpoint is T.38 equipped and the called endpoint is not (supports T.30 only); in addition, the calling endpoint
is improperly configured to initiate T.38 re-INVITEs itself, not waiting for the receiving gateway to do so.
