Description
Defines the Proxy keep-alive time interval (in seconds) between Keep-
Alive messages.
The default value is 60 seconds.
This parameter is applicable only if EnableProxyKeepAlive = 1
(OPTIONS). When EnableProxyKeepAlive = 2 (REGISTER), the
time interval between Keep-Alive messages is determined by the
parameter RegistrationTime.
No [0] = Use the gateways IP address in keep-alive OPTIONS messages
(default).
Yes [1] = Use GatewayName in keep-alive OPTIONS messages.
The OPTIONS Request-URI host part contains either the gateways 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).
No [0] = Gateway fallback is not used (default).
Yes [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 finds an active
Proxy, it switches from internal routing back to Proxy routing.
To enable the redundant Proxies mechanism set
EnableProxyKeepAlive to 1 or 2.
Determines if the local Tel to IP routing table takes precedence over a
Proxy for routing calls.
No [0] = Only Proxy is used to route calls (default).
Yes [1] = The gateway checks the Destination Phone Prefix Address
and/or the Source Phone Prefix field in the Tel to IP Routing table for a
match with the outgoing call. Only if a match is not found, a Proxy is used.
Applicable only if Proxy is not always used (AlwaysSendToProxy
= 0, SendInviteToProxy = 0).
Use the internal Tel to IP routing table to obtain the URI Host name and
(optionally) an IP profile (per call), even if Proxy server is used.
No [0] = Do not use (default).
Yes [1] = Use.
This domain name is used, instead of Proxy name or Proxy IP
address, in the INVITE SIP URI.
No [0] = Use standard SIP routing rules (default).
Yes [1] = All SIP messages and Responses are sent to Proxy server.
Applicable only if Proxy server is used.
No [0] = INVITE messages, generated as a result of Transfer or Redirect,
are sent directly to the URI (according to the Refer-To header in the
REFER message or Contact header in 30x response) (default).
Yes [1] = All INVITE messages, including those generated as a result of
Transfer or Redirect are sent to Proxy.
Applicable only if Proxy server is used and
AlwaysSendtoProxy=0.
