ini File Field Name
Web Parameter Name
Valid Range and Description
UseGatewayNameForOption
s
[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.
Note: 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).
Note: To use ProxyRedundancyMode, enable Keep-alive with Proxy option
(EnableProxyKeepAlive=1 or 2).
