Use Configured IP: If the SIP server is configured as domain name, device will not send DNS queries, but will use “Primary IP” or “Backup IP” to send SIP message if at least one of them is not empty. It will try to use “Primary IP” first, after 3 tries without any response, it will switch to “Backup IP 1”, then “Backup IP 2”, and then it will switch back to “Primary IP” after 3 retries.

DNS SRV use Registered IP

When the HT81x is registered using the second SRV record, making an outbound call, it will try the second SRV (registered IP) first. By default, this option is disabled and the DNS SRV will use first SRV instead of the registered IP.

DNS SRV Failover Mode

Configure the preferred IP mode when DNS Mode is SRV or NAPTR/SRV. · Default SIP request will always be sent to the address with the top priority based on the SRV query result, even if this address is different from the registered IP address. · Saved one until DNS TTL SIP request will always be sent to the registered IP address until DNS TTL expires or registered IP address is unreachable · Saved on until no response SIP request will always be sent to the registered IP address only until registered IP address is unreachable.

Failback Timer

When the primary SBC is up, device will send SIP requests to the primary SBC.

1. Set to “No”: If the “Unregister on reboot” option is set to “No”, it means that the SIP user’s information will not be cleared when the device reboots. In other words, the SIP account will remain registered with the server even after the device is rebooted.
2. Set to “All”: If the “Unregister on reboot” option is set to “All”, it means that all SIP accounts associated with the device will be unregistered when the device reboots. This option clears the SIP user’s information for all the FXS ports on the device.
3. Set to “Instance”: If the “Unregister on reboot” option is set to “Instance”, it means that only the SIP account associated with the concerned FXS port will be unregistered when the device reboots. This option clears the SIP user’s information for only the specific FXS port that is affected by the reboot.

Table 10: FXS Ports

NAT Settings
If you plan to keep the Handy Tone within a private network behind a firewall, we recommend using STUN Server.
The following three settings are useful in the STUN Server scenario:
1. STUN Server (under advanced settings webpage) enter a STUN server IP (or FQDN) that you may have or look up a free public STUN server on the internet and enter it on this field. If using public IP, keep this field blank.
2. Use random SIP/RTP ports (under advanced settings webpage), this setting depends on your network settings. Generally, if you have multiple IP devices under the same network, it should be set to Yes. If using a public IP address, set this parameter to No.
3. NAT traversal (under the FXS web page) Set this to Yes when gateway is behind firewall on a private network.

DTMF Methods

The HT812/HT814 support the following DTMF mode:
· DTMF in-audio
· DTMF via RTP (RFC2833)
· DTMF via SIP INFO

Configuration through a Central Server
The HT812/HT814 can be automatically configured from a central provisioning system.
When HT812/HT814 boots up, it will send TFTP, FTP/FTPS or HTTP/HTTPS requests to download configuration files, “cfg000b82xxxxxx” and “cfg00082xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the HT812/HT814. If the download of “cfgxxxxxxxxxxxx.xml” is not successful, the provision program will issue request a generic configuration file “cfg.xml”. Configuration file name should be in lower case letters. The configuration data can be downloaded via TFTP, FTP/FTPS or HTTP/HTTPS from the central server. A service provider or an enterprise with large deployment of HT812/HT814 can easily manage the configuration and service provisioning of individual devices remotely from a central server.
Grandstream provides a central provisioning system GAPS (Grandstream Automated Provisioning System) to support automated configuration of Grandstream devices. GAPS uses HTTPS and other communication protocols to communicate with each individual Grandstream device for firmware upgrade, remote reboot, etc. Grandstream provides GAPS service to VoIP service providers. Use GAPS for either simple redirection or with certain special provisioning settings. At boot-up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices with redirection settings so that they will be redirected to customer’s TFTP or HTTP/HTTPS/FTP/FTPS server for further provisioning. Grandstream also provides configuration tools (Windows and Linux/Unix version) to facilitate the task of generating device configuration files.
The Grandstream configuration tools are free to end users. The configuration tools and configuration templates are available for download from http://www.grandstream.com/support/tools

the filename in URL for the firmware upgrade has been disabled on the latest firmware upgrade 1.0.43.11
Upgrading via Local TFTP/HTTP/HTTPS/FTP/FTPS Servers
For users that would like to use remote upgrading without a local TFTP/FTP/FTPS/HTTP/HTTPS server, Grandstream offers a NAT-friendly HTTP server. This enables users to download the latest software upgrades for their devices via this server. Please refer to the webpage:
https://www.grandstream.com/support/firmware
Alternatively, users can download for example a free TFTP or HTTP server and conduct a local firmware upgrade. A free window version TFTP server is available for download from:
http://www.solarwinds.com/products/freetools/free_tftp_server.aspx
http://tftpd32.jounin.net/.
Instructions for local firmware upgrade via TFTP:
1. Unzip the firmware files and put all of them in the root directory of the TFTP server. 2. Connect the PC running the TFTP server and the phone to the same LAN segment. 3. Launch the TFTP server and go to the File menu->Configure->Security to change the TFTP server’s default setting from
“Receive Only” to “Transmit Only” for the firmware upgrade. 4. Start the TFTP server and configure the TFTP server in the phone’s web configuration interface. 5. Configure the Firmware Server Path to the IP address of the PC. 6. Save and Apply the changes and reboot the HT812/HT814.
End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use Microsoft IIS web server.
Firmware and Configuration File Prefix and Postfix
Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix. This makes it the possible to store all of the firmware with different version in one single directory. Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching Prefix and Postfix. Thus, multiple configuration files for the same device can be stored in one directory. In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, the device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.
Managing Firmware and Configuration File Download
When “Automatic Upgrade” is set “Yes, every” the auto check will be done in the minute specified in this field. If set to “daily at hour (0-23)”, Service Provider can use P193 (Auto Check Interval) to have the devices do a daily check at the hour set in this field with either Firmware Server or Config Server. If set to “weekly on day (0-6)” the auto check will be done on the day specified in this field. This allows the device to periodically check if there are any new changes need to be taken on a scheduled time. By defining different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware or Provisioning Server load at any given time
Configuration File Download
Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP, FTP/FTPS or HTTP/HTTPS. The Config Server Path is the TFTP or HTTP/HTTPS server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The Config Server Path can be the same or different from the Firmware Server Path.
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 the “New Password” in the Web GUI->Maintenance->Web/SSH Access page->Admin Password. For a detailed parameter list, please refer to the corresponding firmware release configuration template.
When the HT812/HT814 boots up or reboots, it will send a request to download a file named “cfgxxxxxxxxxxxx” followed by a configuration XML file named “cfgxxxxxxxxxxxx.xml”, where “xxxxxxxxxxxx” is the MAC address of the phone, i.e., “cfg000b820102ab” and “cfg000b820102ab.xml”. If the download of “cfgxxxxxxxxxxxx.xml” file is not successful, the provision program will download a generic cfg.xml file and then download cfg.xml. The configuration file name should be in lower case letters.
HT818/HT814 supports DHCP option 67 allowing to provide custom name for the provisioning file. If DHCP option 67 is used, the following file download sequence will be applied:
Step 1: cfg
Step 2: <option 67 bootfile> cfg.xml cfg.xml cfg.xml
Notes:
1. Only XML or binary config file formats are accepted. 2. The MAC header in XML config file should be the device MAC or needs to be removed completely.
