Description
Do not use Proxy [0] = Proxy is not used, the internal routing table is used
instead (default).
Use Proxy [1] = Proxy is used.
If you are using a Proxy server, enter the IP address of the primary Proxy
server in the Proxy IP address field.
If you are not using a Proxy server, you must configure the Tel to IP
Routing table on the gateway (see
Defines the Home Proxy Domain Name.
If specified, the Proxy Name is used as Request-URI in REGISTER,
INVITE and other SIP messages. If not specified, the Proxy IP address is
used instead.
IP address (and optionally port number) of the primary Proxy server you
are using.
Enter the IP address as FQDN or in dotted format notation (for example
201.10.8.1).
You can also specify the selected port in the format: <IP Address>:<port>.
This parameter is applicable only if you select Yes in the Is Proxy Used
field.
If you enable Proxy Redundancy (by setting EnableProxyKeepAlive=1 or
2), the gateway can work with up to four Proxy servers. If there is no
response from the primary Proxy, the gateway tries to communicate with
the redundant Proxies. When a redundant Proxy is found, the gateway
either continues working with it until the next failure occurs or reverts to the
primary Proxy (see the Redundancy Mode parameter). If none of the Proxy
servers respond, the gateway goes over the list again.
The gateway also provides real time switching (hotswap mode), between
the primary and redundant proxies (IsProxyHotSwap=1). If the first Proxy
does not respond to INVITE message, the same INVITE message is
immediately sent to the second Proxy.
If EnableProxyKeepAlive=1 or 2, the gateway monitors the
connection with the Proxies by using keep-alive messages
(OPTIONS or REGISTER).
To use Proxy Redundancy, you must specify one or more
redundant Proxies using multiple ProxyIP= <IP address>
definitions.
When port number is specified (for example, domain.com:5080),
DNS SRV queries are not performed, even if
ProxyDNSQueryType is set to 1.
Use this parameter to assign a name to the gateway (for example,
gateway1.com). Ensure that the name you choose is the one that the
Proxy is configured with to identify your media gateway.
If specified, the gateway Name is used as the host part of the SIP
URI in the From header. If not specified, the gateway IP address
is used instead (default).
