Restrict SMS functions by caller-ID?

I thought I saw this somewhere, but if I did, I can’t find it. Is there a way to limit SMS command use to specific inbound phone numbers? If your number is not on the list, then the command is not processed. I’m going to look again, but if anyone knows for sure this can or cannot be done, please let me know.
Thanks!
UPDATE: And as usual, mere seconds after posting, I find it in the new firmware. Modify SMS rule >Authorization>allowed numbers. This is on ver 7.06.11 firmware for anybody else also not finding this.

TOP - thanks for sharing this info :slight_smile:
