The 9-prefixed 8 and 11 digit strings aren't valid anywhere in north 
america so they are easily identified. I suppose you could also add a 9 
prefixed 12 digit for people who dial 91NPANXXYYYY and 9011X. which is 
also free of collisions.

I dont get any pushback on timeouts for 7D as most users are on a 
deskphone with a dial button or a mobile app. Cell phones have trained 
people to hit send.
