You need to keep the physical address associated with your SIP trunk phone number current for emergency services. That way, if 911 is called from the phone, first responders will know what address to go to. Emergency services will only be routed to the address listed on the My 911 Locations screen. In addition to the address, the first name, last name, and email address must also be assigned to the user. This is known as a primary place of use (PPU).
To assign a SIP trunk phone number to a user:
Your changes are effective immediately.
After you assign a phone number to a user, that person is responsible for keeping the PPU location information current and can do so in Control Center.
After you finish creating a Control Center account, the My 911 Locations screen appears and shows the location for your phone that was assigned when your number was set up.
If you changed the location or added locations, you'll receive an email confirming your changes. (If you don't receive an email, check your profile to make sure your email address is correct, contact your system administrator or contact us.
