Your Lync hard phone and the soft phone on your computer offer an amazing amount of flexibility. One of the most powerful features of Lync is the ability to make calls from any location through the internet via your laptop computer. Unfortunately, the technology of the Emergency 911 system has not kept pace with Lync technology, so even though you can place work calls from home, hotels, or even a cybercafé, the 911 system will recognize the call as being placed from your office. This problem is not unique to Lync. It affects Skype, Vonage, and other IP phone service providers.
Please remember, if you place a 911 call using your Lync soft phone (the Lync client), the 911 system will connect to the Houston emergency services and dispatch responders to your office location that is associated with your phone number.
If you must place a 911 call from an off-campus location using Lync, you must specifically notify the first responder of your actual location. When possible, it would be preferable in those situations to use a local phone or a cellular phone for 911 calls.
