number.
SIP service subscriber's Authenticate ID used for authentication. It can be
identical to or different from the SIP User ID.
The account password required for the phone to authenticate with the ITSP
(SIP) server before the account can be registered. After it is saved, this will
appear as hidden for security purpose.
The SIP server subscriber's name (optional) that will be used for Caller ID
display.
Allows you to access voice messages by pressing the MESSAGE button on
the phone. This ID is usually the VM portal access number. For example, in
Asterisk server, 8500 could be used.
When enabled, only show the action name on the idle screen without the SIP
user ID.
This parameter controls how the Search Appliance looks up IP addresses for
hostnames. There are four modes: A Record, SRV, NATPTR/SRV, Use
Configured IP. The default setting is "A Record". If the user wishes to locate
the server by DNS SRV, the user may select "SRV" or "NATPTR/SRV".
If "Use Configured IP" is selected, please fill in the three fields below:

Primary IP:

Backup IP 1;

Backup IP 2.
If SIP server is configured as domain name, phone will not send DNS query,
but use "Primary IP" or "Backup IP x" to send SIP message if at least one of
them are not empty. Phone will try to use "Primary IP" first. After 3 tries without
any response, it will switch to "Backup IP x", and then it will switch back to
"Primary IP" after 3 re-tries.
If SIP server is already an IP address, phone will use it directly even "User
Configured IP" is selected.
This parameter configures whether the NAT traversal mechanism is activated.
Users could select the mechanism from No, STUN, Keep-Alive, UPnP, Auto or
VPN. If set to "STUN" and STUN server is configured, the phone will route
according to the STUN server. If NAT type is Full Cone, Restricted Cone or
Port-Restricted Cone, the phone will try to use public IP addresses and port
number in all the SIP&SDP messages. The phone will send empty SDP packet
to the SIP server periodically to keep the NAT port open if it is configured to be
