If you use an IP phone service and need help via 911, your opening phrase should indicate your physical location, and then the services that you require. If your call ends up in the wrong jurisdiction, the first thing you want to do is get that call sent to the right place. Making sure that your town/county/suburb is the first thing that the dispatcher hears, makes it more likely that they will indeed "hear" it. We encourage people to say "I am in 'East Podunk' and I need 'the fire department.'"
