Required changes for Nokia 5G home gateway "the trash can"

I'm kind of on the other end of the spectrum of just "wanting a dumb modem", although my wishes would be fulfilled by granting the same request as above:  don't block the existing functionality of the Nokia FastMile gateway.  In addition to having competitive Internet capabilities (multi-100 Mbs speeds would be good enough), I'd like to replace my landline by using the phone capabilities that appear to be already built-in to the Nokia gateway.  I would love it (and you would be getting more revenue out of me) if you would provide an easy home landline number porting service bundled with a fully capable Nokia gateway so I could connect a cordless phone system to it and use my existing home phone number.
