It is used to configure the SIP server subscriber's name (optional) that will be used for
Caller ID display. The configured content will be included in the From, Contact and P-
Preferred-Identity headers of SIP INVITE message.
If the device has an assigned PSTN telephone number, this field should be set to
"User=Phone". Then a "User=Phone" parameter will be attached to the Request-Line
and "TO" header in the SIP request to indicate the E.164 number. If set to "Enable",
"Tel:" will be used instead of "SIP:" in the SIP request. The default setting is "Disable".
Descriptions
It is used to configure the IP address or the domain name of the primary outbound
proxy, media gateway, or session border controller. It is 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.
It is used to configure the 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.
It is used to set which DNS service will be used to look up IP address for SIP server's
hostname. It can be selected from the dropdown list:

A Record


If the device needs DNS SRV resource, in which case the DNS server responds with
more than one result, it should be set to "SRV" or "NATPTR/SRV".
The default setting is "A Record".
It is used to configure the NAT traversal mechanism used on the device. It can be
selected from the dropdown list:

