I probably call 911 more than this entire forum combined I can assure you will have no issues. dialing #'s brings up potential matches, but unless you actually select a match it will dial the #'s by default.
Now if you are wondering why I would dial 911 that much...
I install/maintain/repair cellular E911 equipment-TruePosition LMU's (Location Management Unit) & SIADS (Smart Integrated Access Devices). After installation you have to run a test on each sector (3 sectors) to verify the LMU is providing WPH2 (Wireless Phase 2) information to the PSAP (Public Safety Access Point) You can imagine installing equipment at 100 towers even in a smaller city... 300 call, and that is if every install goes perfect. Not every Dispatcher enjoys your company when you call...
