Table
3-32: Proxy Sets Table Parameters
Parameter
Description
Proxy Set ID
The Proxy Set identification number.
The valid range is 0 to 5 (i.e., up to 6 Proxy Set ID's can be
configured). The Proxy Set ID #0 is used as the default Proxy Set,
and if defined is backward compatible to the list of Proxies from
earlier releases.
Note:
Although not recommended, you can use both default Proxy
Set (ID #0) and IP Groups for call routing. For example, on the
'Trunk Group Settings' page (refer to ''Configuring the Trunk Group
Settings'' on page
), you can configure a Serving IP Group to
where you want to route specific Trunk Group's channels, while all
other device channels use the default Proxy Set. At the same, you
can also use IP Groups in the 'Tel to IP Routing' table (refer to ''Tel
to IP Routing Table'' on page
) or 'Outbound IP Routing' table if
EnableSBC is set to 1 (refer to “Outbound IP Routing Table” on
page
) to configure the default Proxy Set if the parameter
PreferRouteTable is set to 1.
To summarize, if the default Proxy Set is used, the INVITE
message is sent according to the following preferences:
To the Trunk Group's Serving IP Group ID, as defined in the
'Trunk Group Settings' table.
According to the 'Tel to IP Routing' table (or 'Outbound IP
Routing' table if EnableSBC is set to 1), if the parameter
PreferRouteTable is set to 1.
To the default Proxy.
Typically, when IP Groups are used, there is no need to use the
default Proxy, and all routing and registration rules can be
configured using IP Groups and the Account tables (refer to
''Configuring the Account Table'' on page
).
Proxy Address
The IP address (and optionally port number) of the Proxy server.
Up to five IP addresses can be configured per Proxy Set. Enter the
IP address as an FQDN or in dotted-decimal notation (e.g.,
201.10.8.1). You can also specify the selected port in the format:
<IP address>:<port>.
If you enable Proxy Redundancy (by setting the parameter
EnableProxyKeepAlive to 1 or 2), the device can operate with
multiple Proxy servers. If there is no response from the first
(
primary
) Proxy defined in the list, the device attempts to
communicate with the other (
redundant
) Proxies in the list. When a
redundant Proxy is located, the device either continues operating
with it until the next failure occurs, or reverts to the primary Proxy
(refer to the parameter ProxyRedundancyMode). If none of the
Proxy servers respond, the device goes over the list again.
The device also provides real-time switching (Hot-Swap mode)
between the primary and redundant proxies (refer to the parameter
IsProxyHotSwap). If the first Proxy doesn't respond to the INVITE
message, the same INVITE message is immediately sent to the
next Proxy in the list. The same logic applies to REGISTER
messages (if RegistrarIP is not defined).
