I know all this.

My question came from the fact that as strange as it may seem, SPA3102
and similar products do not offer the SIP features depending on
terminating/originating port.
More precisely, when a SIP fax call comes in through an FXS port, it
triggers T.38 while it doesn't trigger T.38 when an FXO port is used

Yes, sure.
