Hi all, I would like to map a 4-digit extension (1234) to one of our other offices in a different state. I would like the 4-digit extension to actually dial the full 11-digit number (1-222-333-1234). I know this is possible but I have never programmed this before. We have an Option 11C unit, and I am pretty familiar with it, though I am by no means an "expert". Any walk-through advice on this would be greatly appreciated! Thanks in advance!
