You can employ alternative routing with this option. If no
response is received from any of the redundant (online) proxies
or the proxies reject the message with a SIP response code
that you have configured in the Alternative Routing Reasons
table, the device searches the IP-to-IP Routing table for an
alternative routing rule and if found, sends the message to the
rule's destination.
Enables load balancing between proxy servers of the Proxy Set.
■ [0] Disable = (Default) Disables proxy load balancing.
■ [1] Round Robin = The device sends outgoing SIP messages
to the online proxy servers of the Proxy Set in a round-robin
fashion. The order of the round-robin is determined by the listed
order of the IP addresses in the Proxy Address table and their
priority. You can configure priority of each IP address using the
'Proxy Priority' parameter (see below). For DNS-resolved IP
addresses for proxy servers configured with an FQDN
(including NAPTR and SRV, if configured), the priority is
received from the DNS.The IP address list is refreshed every
user-defined interval (see the ProxyIPListRefreshTime
parameter). If a change in the order of the IP address entries in
the list occurs, all load statistics are erased and balancing
starts over again.
■ [2] Random Weights = The outgoing requests are not
distributed equally among the proxy servers. The distribution is
determined by the weight of the proxy servers. You can
configure the weight per proxy server, using the 'Proxy Random
Weight' parameter in the Proxy Address table (see below). For
proxy servers configured with an FQDN, the weight of each
DNS-resolved IP address is received from the DNS server
(using SRV records). However, if you have configured the
weight for the FQDN in the 'Proxy Random Weight' parameter,
this parameter's value overrides the weight from the DNS
server. The device sends the requests in such a fashion that
each proxy receives a percentage of the requests according to
its' weight.
Defines the minimum number of proxies in the Proxy Set that must
be online for the device to consider the Proxy Set as online, when
proxy load balancing is used.
The valid value is 1 to 15. The default is 1.
Note: The parameter is applicable only if proxy load balancing is
enabled (see the 'Proxy Load Balancing Method' parameter,
above).
Defines how the device classifies incoming IP calls to the Proxy
Set.
■ [0] IP Address only = (Default) Classifies calls to the Proxy
Set according to IP address only.
