ini File Field Name
Web Parameter Name
Valid Range and Description
SessionExpiresMethod
[Session Expires Method]
Defines the SIP method used for session-timer updates.
0 = Use Re-INVITE messages for
session-timer updates (default)
.
1 = Use UPDATE messages.
The gateway can receive session-timer refreshes using both
methods.
UseGatewayNameForOptio
ns
[Use Gateway Name for
OPTIONS]
0 = Use the gateway’s IP address in keep-alive OPTIONS messages
(default).
1 = Use ‘GatewayName’ in keep-alive OPTIONS messages.
The OPTIONS Request-URI host part contains either the gateway’s IP
address or a string defined by the parameter ‘Gatewayname’.
The gateway uses the OPTIONS request as a keep-alive message to its
primary and redundant Proxies (EnableProxyKeepAlive = 1).
IsProxyHotSwap
[Enable Proxy Hotswap]
Enable Proxy Hot Swap redundancy mode.
0 = Disabled (default)
1 = Enabled
If Hot Swap is enabled, SIP INVITE message is first sent to the primary
Proxy server. If there is no response from the primary Proxy server for
‘ProxyHotSwapRtx’ retransmissions, the INVITE message is resent to the
redundant Proxy server.
ProxyHotSwapRtx
[Number of RTX before
Hotswap]
Number of retransmitted INVITE messages before call is routed (hot swap)
to another Proxy
The valid range is 1 to 30. The default value is 3.
This parameter is also used for alternative routing using the
Tel to IP Routing table. If a domain name in the routing table is
resolved into 2 IP addresses, and if there is no response for
‘ProxyHotSwapRtx’ retransmissions to the INVITE message
that is sent to the first IP address, the gateway immediately
initiates a call to the second IP address.
ProxyRedundancyMode
[Redundancy Mode]
0 (Parking mode) = the gateway continues working with the last active
Proxy until the next failure (default).
1(Homing mode) = the gateway always tries to work with the primary Proxy
server (switches back to the primary Proxy whenever it is available).
To use ProxyRedundancyMode, enable Keep-alive with Proxy
option (EnableProxyKeepAlive=1 or 2).
IsFallbackUsed
[Enable Fallback to Routing
Table]
0 = Gateway fallback is not used (default).
1 = Internal Tel to IP Routing table is used when Proxy servers are not
available.
When the gateway falls back to the internal Tel to IP Routing table, the
gateway continues scanning for a Proxy. When the gateway locates an
active Proxy, it switches from internal routing back to Proxy routing.
To enable the redundant Proxies mechanism set
‘EnableProxyKeepAlive’ to 1 or 2.
UserName
[User Name]
Username used for Registration and for Basic/Digest authentication
process with Proxy / Registrar.
Parameter doesn’t have a default value (empty string).
