User's Manual 19. Control Network
Parameter Description
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
CLI: control-network
proxy-ip > 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
CLI: control-network
proxy-set > proxy-
enable-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
SBC application). Any response from the Proxy, either success (200 OK)
or failure (4xx response) is considered as if the Proxy is communicating
correctly.
Notes:
 For Survivability mode for User-type IP Groups, this parameter must be
enabled (1 or 2).
 This parameter must be set to 'Using Options' when Proxy redundancy
is used.
 When this parameter is set to 'Using Register', the homing redundancy
mode is disabled.

When the active proxy doesn't respond to INVITE messages sent by the
device, the proxy is tagged as 'offline'. The behavior is similar to a
Keep-Alive (OPTIONS or REGISTER) failure.
 If this parameter is enabled and the proxy uses the TCP/TLS transport
type, you can enable CRLF Keep-Alive mechanism, using the
UsePingPongKeepAlive parameter.
Web: Proxy Keep
Alive Time
EMS: Keep Alive
Time
CLI: control-network
proxy-set > proxy-
keep-alive-time
[ProxySet_ProxyKee
pAliveTime]
Defines the Proxy keep-alive time interval (in seconds) between Keep-Alive
messages.
The valid range is 5 to 2,000,000. The default is 60.
Note: This parameter is applicable only if the parameter
EnableProxyKeepAlive is set to 1 (OPTIONS). When the parameter
EnableProxyKeepAlive is set to 2 (REGISTER), the time interval between
Keep-Alive messages is determined by the RegistrationTime parameter for
the Gateway/IP-to-IP application or SBCProxyRegistrationTime parameter
for the SBC application.
Web: Proxy Load
Balancing Method
EMS: Load Balancing
Enables the Proxy Load Balancing mechanism per Proxy Set ID.
 [0] Disable = Load Balancing is disabled (default)
 [1] Round Robin
