 To configure Proxy Redundancy using the Configuration File:
• Use the table below as reference.
Table 17-3: SIP Proxy Server Redundancy Parameters
Parameter Description
[voip/signaling/sip/redundant_proxy/enabled]
Mandatory for the phone to operate in
redundancy.
Commands the phone to operate with the
other voip/signalling/sip/redundant_proxy
parameters.
Redundant Proxy Mode
[voip/signalling/sip/redundant_proxy/mode]
Mandatory for the phone to operate in
redundancy. Defines the two proxies' mode of
operation: Primary-Fallback or Simultaneous.
Defines a backup SIP proxy server to increase
QoS stability. Enable the parameter if you
want to operate with a proxy server that will
serve as a backup if the first goes down.
 Disable = (Default) Phone doesn't use
redundant proxy. If set to Disable in the
Web interface, it will set the previously
described ini file parameter
redundant_proxy/enabled as well.
 Primary-Fallback = Phone registered to
redundant proxy if the primary proxy does
not respond to SIP signaling messages.
 Simultaneous = Applies only in some
environments. If selected, dual registration
is performed; the phone registers
simultaneously to both servers.
See Appendix A.3.4.
Redundant Proxy Address
[voip/signalling/sip/redundant_proxy/address]
[Only displayed if the 'Redundant Proxy Mode'
parameter is enabled (Primary-Fallback)]
Defines the IP address of the backup proxy
server. Default:
0.0.0.0
Redundant Proxy Keep Alive Period
voip/signalling/sip/redundant_proxy/keepalive
_period
[Only displayed if the 'Redundant Proxy Mode'
parameter is enabled (Primary-Fallback)]
Defines how often a keep alive message is
sent by the phone to the proxy server.
Range: 0 to 300.
Default: Every 60 seconds.
Redundant Outbound Proxy Port
voip/signalling/sip/redundant_proxy/port
[Only displayed if the 'Redundant Proxy Mode'
parameter is enabled (Primary-Fallback)]
Defines the UDP or TCP port of the backup
redundant proxy server. If occupied by other
enterprise devices, you can configure another.
Range: 1024 to 65535. Default = 5060.
