Parameter Description
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 (see 'Configuring Account Table' on page
243 ).
Proxy Address
[ProxyIp_IpAddress]
Defines the address (and optionally, port number) of the Proxy server. Up
to five addresses can be configured per Proxy Set.
The address can be defined as an IP address in dotted-decimal notation
(e.g., 201.10.8.1) or FQDN. You can also specify the port in the format:

For IPv4 address: <IP address>:<port> (e.g., 201.10.8.1:5060)

For IPv6 address: <[IPV6 address]>:<port> (e.g.,
[2000::1:200:200:86:14]:5060)
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.
Transport Type
[ProxyIp_TransportT
ype]
Defines the transport type of the 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.
Web/EMS: Enable
Proxy Keep Alive
[ProxySet_EnablePr
oxyKeepAlive]
Enables the Keep-Alive mechanism with the Proxy server(s).

[0] Disable (default).

[1] Using Options = Enables Keep-Alive with Proxy using SIP OPTIONS
messages.

[2] Using Register = Enables Keep-Alive with Proxy using SIP
REGISTER messages.
If set to 'Using Options', the SIP OPTIONS message is sent every user-
defined interval (configured by the parameter ProxyKeepAliveTime). If set
to 'Using Register', the SIP REGISTER message is sent every user-
defined interval (configured by the RegistrationTime parameter for the
Gateway/IP-to-IP application or SBCProxyRegistrationTime parameter for
