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 'Hunt Group Settings'

page (refer to ''Configuring the Hunt Group Settings'' on page 183), you can

config

ure a Serving IP Group to where you want to route specific

HuntGroup's endpoints, while all other device endpoints 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 160) to configure the default

Proxy Set if

the parameter PreferRouteTable is setto 1.

To summarize, if the default Proxy Set is used, the INVITE message is sent

according to the following preferences:

 To the Hunt Group's Serving IP Group ID, as defined in the 'Hunt Group

Settings' table.

 According to the 'Tel to IP Routing' table, 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 188).

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).

Notes:

 If EnableProxyKeepAlive is set to 1 or 2, the device monitors the

connection with the Proxies by using keep-alive messages (OPTIONS or
