7.1.1 Configuring SAS
For configuring the device to operate with SAS, perform the following configurations:
IsProxyUsed = 1
ProxyIP 0 = <SAS agent's IP address, i.e., the device>
ProxyIP 1 = <external Proxy server IP address>
IsRegisterNeeded = 1 (for the device)
RegistrarIP = ‘ ‘
SIPDestinationPort = 5080
IsUserPhone = 0 (don’t use “user=phone” in SIP URL)
IsUserPhoneInFrom = 0 (don’t use “user=phone” in From Header)
IsFallbackUsed = 0
EnableProxyKeepAlive = 1 (enables keep-alive with Proxy using OPTIONS)
EnableSAS = 1
SASLocalSIPUDPPort = (default 5080)
SASRegistrationTime = <expiration time that SAS returns in the 200 OK to REGISTER
in Emergency mode> (default 20)
SASDefaultGatewayIP = < SAS gateway IP address>
SASProxySet = 1
7.1.2 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 260).
