If you set up an emergency route and/or outbound notification, of course you should NOT dial 911 to test it! This would generate an actual emergency call!
Instead, include "933" as a dialpattern in your emergency route, and then dial 933. This will reach an automated address verification service that plays back your e911 address information. Not all service providers offer 933 as a test service. If 911 must be called for testing, make sure it is clearly stated to the operator that the call is a test.
