Caveats:

• Google Voice:
  • when an SMS is sent from a Google Voice number to the SIM card number
    • everything works as expected
  • when an SMS is sent to a Google Voice number
    • the sender of the SMS message will always be a number belonging to the Google Voice backend infrastructure
    • keep this in mind when setting forwarding filters
