IntelePeer has recently begun offering Enhanced 911 (e911) services which diretly integrate with Lync Server 2010. Enhanced 911 allows the Lync Location Information Service to query your on-prem database (LIS database) for known locations and publish that information to the 911 service. In addition, when the information has been entered manually the 911 service is aware the address has not been verified and an operator assists the process.
The e911 service is an optional service that incurs an additional fee per month. Contact your IntelePeer sales representative today and extend your Lync services to include emergency. For those that are not using IntelePeer for their voice services, consider trialing their 30-day free/no obligation service and see how you can use VoIP services for a fraction of the cost of traditional PSTN (tell them BriComp sent you!).
