This parameter defines whether the IPS-3101h NAT traversal mechanism will be activated or not. If activated (by choosing “Yes”) and a STUN server is also specified, then the IPS-3101h will behave according to the STUN client specification. Under this mode, the embedded STUN client inside the IPS-3101h will attempt to detect if and what type of firewall/NAT it is behind through communication with the specified STUN server. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the IPS-3101h will attempt to use its mapped public IP address and port in all the SIP and SDP messages it sends out.

If this field is set to “Yes” with no specified STUN server, then the IPS- 3101h will periodically (every 10 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.

NAT IP address used in SIP/SDP message. Default is blank.

This is the IP address of the configured tftp server. If it is non-zero or not blank, the IPS-3101h will attempt to retrieve new configuration file or new code image from the specified tftp server at boot time. It will make up to 3 attempts before timeout and then it will start the boot process using the existing code image in the Flash memory. If a tftp server is configured and a new code image is retrieved, the new downloaded image will be verified and then saved into the Flash memory.

Default is NO. When set to Yes a SUBSCRIBE for Message Waiting Indication will be sent periodically.

This parameter allows the 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 IPS-3101h will automatically append the “@” and the host portion of the corresponding SIP address.

Default is No. If set to Yes, Call Forwarding & Do-Not-Disturb are supported locally

Default is Not.

This parameter controls the way DTMF events are transmitted. There are 3 ways: in audio which means DTMF is combined in audio signal (not very reliable with low-bit-rate codec), via RTP (RFC2833), or via

SIP INFO.
