922 is to test that your information is correct if you dial 911 without reaching a 911 operator.

A recorded message will play your phone number and address when dialed if E911 is assigned to your DID.

Repeat steps 5 and 6 for 922. For the "Number" field use 922 instead of 911.

Repeat steps 5-7 for each E911 address/DID you have.
