[. . . ] Allows users to forward a matching (TCP/UDP) port to a specific LAN IP address with a specific (TCP/UDP) port. Any time user can make PSTN calls from the analog phone connected to FXS port. By default, user may pick up the phone, dial *00, and after obtaining PSTN line ( user will hear regular dial tone) normal PSTN dialing is allowed. PIN code to bridge from VoIP to PSTN (Maximum 8 digits, No Default) PIN code to bridge from PSTN to VoIP (Maximum 8 digits, No Default) If the dialed digits match one of the specified prefix here, outbound calls will be initiated from PSTN line. Calls are unconditionally forwarded to the specified PSTN phone number for all incoming VoIP calls on FXO port. Calls are unconditionally forwarded to the specified VoIP phone number for all incoming PSTN calls. Each incoming call from the PSTN will first ring the analog phone connected to FXS port. This call from the PSTN network will be forwarded to the preconfigured VoIP extension if it is not answered. User can configure the number of rings before forwarding calls to the VoIP extension. Configure number of rings using the "number of rings" parameter located in the FXO Port Configuration page.

HT503 User Manual Firmware 1. 0. 0. 9 Page 21 of 37 Last Updated: 9/2007 ADVANCED CONFIGURATION AND FXS/FXO PORTS PARAMETERS To login to the Advanced Setting and FXS port configuration pages, administrator password is required. The password is case sensitive and the maximum length is 25 characters. TABLE 9: HT503 ADVANCED SETTINGS PAGE DEFINITIONS Admin Password Administrator password. Only the administrator can configure the "Advanced Settings" page. Password field is purposely blanked for security reason after clicking update and saved. This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or Diff-Serv or MPLS. This parameter specifies how often the HT503 sends a blank UDP packet to the SIP server in order to keep the NAT "pin hole" open. Enables the HT503 to download firmware or configuration files through either TFTP or HTTP servers. If this is configured, the HT503 retrieves the new configuration file or new code image from the specified TFTP server at boot time. After 5 attempts, the system will timeout and 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 is saved into the Flash memory. Note: Firmware upgrades may take up to 10 minutes depending on your network environment. Please do NOT interrupt the TFTP upgrade process (especially the power supply) as this will damage the device. [. . . ] A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric numbers. i. e. , P2 is associated with "Admin Password" in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding firmware release configuration template. [. . . ]
