Parameter
Proxy Address
Transport Type
Version 5.4
To summarize, if the default Proxy Set is used, the INVITE message is sent
according to the following preferences:
To the Trunk Group's ServingIPGroupID, as defined in the 'Trunk 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 232).
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
REGISTER).
To use Proxy Redundancy, you must specify one or more redundant
Proxies.
When a port number is specified (e.g., domain.com:5080), DNS
NAPTR/SRV queries aren't performed, even if ProxyDNSQueryType is
set to 1 or 2.
The transport type per Proxy server.
[0] UDP
[1] TCP
[2] TLS
[-1] = Undefined
Note: If no transport type is selected, the value of the global parameter
SIPTransportType is used (refer to ''SIP General Parameters'' on page 134).
