Skype for Business, E911 General Information

This page provides information on E911 with Skype for Business Enterprise Voice software client (aka Skype for Business).

E911 with Skype for Business Enterprise Voice

E911 stands for Enhanced 911. Unlike standard 911, E911 provides the 911 call center with the caller’s phone number and location. Much like the limitations of E911 with cell phones, it is imperative that UC Voice users are aware of the current limitations of E911 and Skype for Business.

One of the benefits of Skype for Business is that it is portable. UC Voice users can make Skype for Business calls from any location with internet access as long as they also have access to the Microsoft Skype for Business software client and are logged into their account. Needless to say, this benefit can create some serious limitations when it comes to providing proper location information to 911 call centers.

The Internet connection used may not automatically correspond to a specific geographic location; therefore, whoever receives the call may not automatically receive the correct geographical location information. Specifically, 911 calls made over the wireless network on campus may provide less accurate location information.

Accessing emergency services by dialing 911 using UC Voice may be limited in the following ways:

Initially the Federal Communications Commission (FCC) did not regulate Voice over IP service providers with regards to 911. The FCC changed their approach in 2005 and set forth several requirements that all providers of VoIP service – including the University – must follow.

Technology Services works with University of Illinois Police Department, METCAD (Champaign/Urbana Public Safety Answering Point), and a 3rd-Party vendor to provide the best possible E911 solution to campus.

E911 Acknowledgement Form and Stickers

The Code of Federal Regulations (CFR) (external link) requires the University to obtain and keep a record of affirmative acknowledgement by every subscriber (UC Voice users), both new and existing, of having received and understood the advisory statement provided on the E911 Acknowledgement (external link) page. It is required that UC Voice users read the advisory statement about E911 and UC and acknowledge that they have read the statement.

Additionally, the CFR requires the University to distribute stickers to its existing subscribers, warning that E911 service may be limited or not available when using Lync/Skype for Business. Technology Services strongly recommends the use of a traditional landline phone or cell phone when it is necessary to call 911. Technology Services is providing Pinnacle Department Managers these E911 warning stickers for distribution to their unit/department UC Voice users. These stickers are to be placed directly on or near all Skype for Business-enabled devices (phone, desktop, laptop). If users need stickers, Technology Services suggests they contact their UC Support Staff, which include IT Professionals and Pinnacle Department Managers.  For a listing of Pinnacle Department Managers, please follow this link:
