9.2.2 Configuring Emergency Calls
The device's SAS agent can be configured to detect a user-defined, emergency number
(e.g. 911 in North America), which it then redirects the call directly to the PSTN (through its
FXO interface). The emergency number is configured using the ini file parameter
SASEmergencyNumbers (for a detailed description, refer to ''SIP Configuration
Parameters'' on page 252).

ice's SAS Agent Redirecting Emergency Calls to PSTN
To configure support for emergency calls, configure the parameters below. The device and
the SAS feature are configured independently. If the device and the SAS agent use
different proxies, then the device's proxy server is defined using the 'Use Default Proxy'
parameter, while the SAS proxy agent is defined using the 'Proxy Set' table and
SASProxySet parameter.
