SIP Server
This field contains the URL string or the IP address (and port, if different from 5060) of
the SIP proxy server. e.g., the following are some valid examples: sip.my-voip-
provider.com, or sip:my-company-sip-server.com, or 192.168.1.200:5066

Outbound Proxy
IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border
Controller. Used by ATA for firewall or NAT penetration in different network
environment. If symmetric NAT is detected, STUN will not work and ONLY Outbound
Proxy will work.

SIP Transport
User can select UDP or TCP or TLS.
NAT Traversal (STUN)
This setting decides whether the NAT traversal mechanism is activated. It should be
set to “Yes” if the device is behind a NAT router. If no outbound proxy is configured, a
STUN server needs to be set to activate STUN detection mechanism. Usually ITSP will
provide these settings. If this field is set to “Yes”, then the device will periodically send
a dummy UDP packet to the SIP server to pinhole the NAT.

SIP User ID
User account information, provided by VoIP service provider (ITSP), usually has the
form of digit similar to phone number or actually a phone number. This field contains
the user part of the SIP address for this phone. e.g., if the SIP address is
sip:my_user_id@my_provider.com, then the SIP User ID is: my_user_id.
Do NOT include the preceding “sip:” scheme or the host portion of the SIP address in
this field.

Unregister on Reboot
Default is No. If set to yes, the device will first send registration request to remove all
previous bindings. Use only if proxy supports this remove bindings request.
