Get Asterisk/Freepbx to ignore digits that were unnecessarily dialed (area code for local calls)

Question

This is the second part of this question, worded better.

Remove local area code on outbound calls, and remove "dial 1" for long distance in Trixbox/Asterisk

I have removed the NEED to dial 933 or 1+933 for long distance or local calls already. Additionally, what I want to do is to have Asterisk IGNORE these digits if someone unnecessarily dials them.

So, Joe Dirt calls 1-933-337-0003 when he really could have dialed 337-0003 since it was a local call. Right now, Asterisk is telling him to hang up and try again since this is a local call, and the 1 and/or 933 is not necessary. I want Asterisk to realize Joe Dirt is dumb, and just ignore the extra digits that were dialed and continue his call as though he had only dialed 337-0003.*

*While keeping the existing rules in place.

Answer 1

You need just strip digits. i.e in freepbx do rule 1933+NXXXXXX in the TRUNK
