Update a Location

If you move an MITvoip phone, it is your responsibility to update the phone's location so that emergency services can find you if you call 100 or 911. You can update the location for most phones in Employee Self Service (ESS).

However, some phones are not listed in ESS. This is typically the case with phones not assigned to one particular user, such as common area or conference room phones. Update locations for multiple-user phones with the Account Management tools.

Note: If you temporarily move your phone for less than 24 hours and then return it to your original location, do not update the phone location. However, be aware of your location when making an emergency call.

Update a Location in Employee Self Service:

Go to SAPweb Self Service and select the Personal Information tab.
Select Work Address and Phone from the pull-down menu.
Change the appropriate information (e.g., building and room).

Update a Location with Account Management:

If you relocate a phone that is not listed in Employee Self Service, contact the phone's registered owner (usually your local telephone administrator or AO). The registered owner must update the location with Account Management: Change Location.

Note: Use this method when you move a phone whose number is not listed in Employee Self Service (ESS). If the phone is listed, please use ESS to update the location.

Emergency Calls on WiFi Phones

IS&T recommends that you do not make emergency calls from your MITvoip WiFi (portable wireless) phone. Use an alternative wired phone whenever possible, including the MIT blue phones at strategic locations on campus.

Your WiFi phone will work from anywhere on campus and from many off-campus locations. However:

If you dial 100, the call will always go to MIT Police. If you dial from an on-campus location, MIT Police may have incorrect information about your location.
If you dial 911, the call will always go to Cambridge Police. The Cambridge Police will not know your location.
If you are dialing from off campus (or away from Cambridge), you will have to tell MIT Police or Cambridge Police where you are located. They will then route your call to the appropriate emergency response center.
If you are dialing from an international location, emergency services will not be available. Calls to MIT Police or Cambridge Police may not be able to be routed to international emergency response centers.

Location Information for Police

Because MITvoip phones are not bound to a particular location, emergency services might not have accurate information about where you are if the phone has been moved.

MIT Police 100 Calls

The building and office number are based on data in SAP, which provides the specific office location to MIT Police.
The building number in SAP is verified against the building number associated with the phone's network (IP) address.
If the building and office number in SAP are not the same as the building number associated with the phone's network address, then only the building number associated with the phone's network address is given to MIT Police.

Cambridge Police 911 Calls

Cambridge Police does not receive MIT building and office locations on 911 calls.
Cambridge Police often refers 911 calls to the MIT Police.

Future Enhancements to Emergency Calling

IS&T is currently working on methods based on network infrastructure that will automatically identify the office location or nearest WiFi access point when you dial 100. This will eliminate the need to update location information via a web site.

Updates to the community will be provided as this capability nears completion.

For more information, see the MITvoip Project Update.
