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 157).
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 ''Configuring SIP
General Parameters'' on page 145).
