Network Settings
Outbound Proxy
Configures the IP address or the domain name of the primary outbound
proxy, media gateway or session border controller. It's used by the device
for firewall or NAT penetration in different network environments. If a
symmetric NAT is detected, STUN will not work and only an outbound
proxy can provide a solution
Secondary Outbound
Proxy
Sets IP address or domain name of the secondary outbound proxy, media
gateway or session border controller. The device will try to connect the
Secondary outbound proxy only if the primary outbound proxy fails.
DNS Mode
Defines which DNS service will be used to lookup IP address for SIP
server’s hostname. There are three modes:
•
A Record
•
SRV
•
NATPTR/SRV
To locate the server by DNS SRV set this option to "SRV" or
"NATPTR/SRV". Default setting is "A Record".
Maximum Number of SIP
Request Retries
Sets the maximum number of retries for the device to send requests to the
server. In DNS SRV configuration, if the destination address does not
respond, all request messages are resent to the same address according
to the configured retry times. Valid range: 1-10. The default setting is 4.
