TABLE 10: ACCOUNT SETTINGS

When set to Yes the FXS port is activated.
SIP Server's IP address or Domain name provided by VoIP service provider.
Failover SIP Server's IP address or Domain name in case primary server does not
respond.
Default is no. If set to yes it will register to Primary Server if registration with Failover
server expires
IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border
Controller. Used by HT502 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.
User can select UDP or TCP or TLS.
This parameter defines whether or not the HT502 NAT traversal mechanism is
activated. If activated (by choosing "Yes") and a STUN server is also specified, then the
HT502 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 HT502 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 HT502 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.
User account information, provided by VoIP service provider (ITSP). Usually in the form
of digit similar to phone number or actually a phone number.
SIP service subscriber's Authenticate ID used for authentication. Can be identical to or
different from SIP User ID.
SIP service subscriber's account password.
SIP service subscriber's name for Caller ID display.
One from the 3 modes are available for "DNS Mode" configuration:
-A Record (for resolving IP Address of target according to domain name)
-SRV (DNS SRV resource records indicates how to find services for various protocols)
