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 (every Keep-alive
interval) send a dummy UDP packet to the SIP server to pinhole the NAT.
Default is 20 seconds. The minimum value allowed is 10 seconds. This is the
interval of sending dummy UDP packet to keep the NAT "pin hole" open.
If configured, the NAT IP address will be used in SIP/SDP message. Default is
blank.
Use STUN keep-alive to detect WAN side network problems. If keep-alive
request does not yield any response for configured number of times, the device
will restart the TCP/IP stack. If the STUN server does not respond when the
device boots up, the feature is disabled.
SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.
Indication will be sent periodically.
This parameter allows a user to configure a User ID or extension number to be
automatically dialed upon offhook. Please note that only the user part of a SIP
address needs to be entered here. The HandyTone ATA will automatically
append the "@" and the host portion of the corresponding SIP address.
Note: Please write down the IP address of the ATA if you use this feature as it
will prevent you to access the IVR and the only way to access the device
configuration is via the web configuration page.
Default is "Yes". Advanced call features using start codes are supported
locally.
If this parameter is set to "Yes", user will be able to make Bellcore style 3-way
conference. *23 will be disabled.
Default is "No". User can use star codes to enable/disable call waiting.
Default is "No".
