TABLE 10: ACCOUNT SETTINGS

Account Active

When set to Yes the FXS port or Profile (for HT704) is activated.

Primary SIP Server

SIP Server‘s IP address or Domain name provided by VoIP service provider.

Failover SIP Server

Failover SIP Server‘s IP address or Domain name in case primary server does not

respond.

Prefer Primary SIP

Server

Default is No. If set to yes, it will register to Primary Server if registration with Failover

server expires

Outbound Proxy

IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border

Controller. Used by HT802 for firewall or NAT penetration in different network

environments. If symmetric NAT is detected, STUN will not work and ONLY outbound

proxy can correct the problem.

SIP transport

User can select UDP or TCP or TLS. Default is UDP.

NAT Traversal (STUN)

This parameter defines whether or not the HT802 NAT traversal mechanism is

activated. If activated (by choosing ―Yes‖) and a STUN server is also specified, then the

HT802 performs according to the STUN client specification. Using this mode, the

embedded STUN client will detect if and what type of firewall/NAT. If the detected NAT

is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the HT802 will use its

mapped public IP address and port in all of its SIP and SDP messages.

If the NAT Traversal field is set to ―Yes‖ with no specified STUN server, the HT802 will

periodically (every 20 seconds or so) send a blank UDP packet (with no payload data)

to the SIP server to keep the ―hole‖ on the NAT open.

SIP User ID

User account information, provided by VoIP service provider (ITSP). Usually in the form

of digit similar to phone number or actually a phone number.

Authenticate ID

SIP service subscriber‘s Authenticate ID used for authentication. Can be identical to or

different from SIP User ID.
