Enable E911 services on your phone
list-menuFeedback?
This Help article is for Cisco Wireless Phone 9821 registered to Cisco Unified Communications Manager (Unified CM).

Historically, Cisco Emergency Responder (CER) and RedSky have worked together to provide compliant E911 services. As an alternative, we now offer another method for connecting to RedSky using the HTTP Enabled Location Delivery (HELD) protocol. Beginning with PhoneOS release 4.0.1, this new method of using HELD with E911 services are disabled on phones by default and must be manually enabled in Cisco Unified CM before users can access them. Before enabling E911 with this new HELD method, it is important to carefully assess all dependencies and perform a comprehensive end-to-end evaluation of your infrastructure.

The E911 setting described on this page don't work with Cisco Emergency Responder (CER) and requires appropriate licensing and provisioning from the third-party E911 service provider.

Before you begin

Before enabling E911 services on your phones, make sure that E911 has been properly provisioned in Cisco Unified CM by following the procedures in Feature Configuration Guide for Cisco Unified Communications Manager, Release 15 and SUs.

In Cisco Unified Communications Manager Administration, perform one of the following actions as needed:

  • To configure all deployed phones, go to System > Enterprise Phone Configuration.
  • To configure phones sharing the same phone profile, go to Device > Device Settings > Common Phone Profile.
  • To configure an individual phone, go to Device > Phone. Then find your phone and open the Phone Configuration page.

The configuration follows a hierarchical structure:

  • Individual device settings take precedence over settings in the common phone profile and enterprise level
  • Common phone profile settings override enterprise-level settings
