Emergency Call

Emergency Call

This section describes how to configure the emergency call service. The IP phone allows users to make emergency calls even if it is locked or unregistered.


The administrator configures the physical location information on the USM(EC6.X). Terminals report their current locations to the server when they are logged in. The location information helps the emergency contact center to locate the terminals when emergency calls are made. This is called the LBS.

The location information is configured by the administrator on the USM(EC6.X), and it is not automatically collected by certain programs on the terminals. In addition, the location information indicates physical locations within the enterprise and does not belong to personal privacy. When configuring the location information, the administrator needs to comply with local laws and regulations.


  • The emergency call service has been configured on the SIP server.

    For details about how to configure the emergency call service on a SIP server, see the product documentation of the gateway that serves as the SIP server.

  • You have obtained and configured the SIP server address for the IP phone.

Configuration Methods

You can configure the emergency call service using three different methods, as listed in Table 5-8.
