Note: No dial tone will be played between steps 1 and 2 and destination ports can be specified using “*” (encoding for “:”) followed by the port number.
Examples of Direct IP Calls:
a) If the target IP address is 192.168.0.160, the dialing convention is *47 or Voice Prompt with option 47, then 192*168*0*160, followed by pressing the “#” key if it is configured as a send key or wait 4 In this case, the default destination port 5060 is used if no port is specified
b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be: *47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds.
Note: When completing direct IP call, the “Use Random SIP/RTP Port” should set to “NO”.
Call Hold
You can place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button).
Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash” button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.

When attended transfer fails and A hangs up, the HT81x V2 will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B
3-Way Conferencing
The HT81x V2 supports Bellcore style 3-way Conference. To perform the 3-way conference, we assume that the call is established between phone A and B are in conversation. Phone A (HT81x V2) wants to bring third phone C into conference:
- Phone A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone.
- Phone A dials C’s number then # (or wait for 4 seconds).
- If phone C answers the call, then A presses FLASH to bring B, C in the conference.
- If phone C does not answer the call, phone A can press FLASH back to talk to phone B.
- If phone A presses FLASH during conference, the phone C will be dropped out.
- If phone A hangs up, the conference will be terminated for all three parties when configuration “Transfer on Conference Hang up” is set to “No”. If the configuration is set to “Yes”, A will transfer B to C so that B and C can continue the conversation.
Call Return
To call back to the latest incoming number.
- Pick up the handset of the connected phone (Off-hook).
- After hearing the dial tone, input “*69”.
- Your phone will automatically call back to the latest incoming number.
All star codes (*XX) related features mentioned above are supported by ATA default settings. If your service provider provides different feature codes, please contact them for instructions.
Inter-Port Calling
In some cases, a user may want to make phone calls between the phones connected to multiple ports of the same HT81x V2 when it is used as a standalone unit, without the use of a SIP server. In such cases, users still will be able to make inter-port calls by using the IVR feature.
On the HT81x V2 inter-port calling is achieved by dialing ***7X (X is the port number). For example, the user connected to port 1 can be reached by dialing *** and 71.
Voice Mail
VM Notification
The HT81x V2 indicates new voice mail messages using Phone LEDs and Stutter Tone.
The Phone LEDs on HT81x V2 will start blinking slowly when a new voice mail message is available on corresponding account.
A stutter tone will be played at first few seconds followed by dial tone when picking up the handset.
Note: New VM messages can be also indicated by LED blink, screen display, etc… if they are supported on connected analog phones.

Upgrading via Local TFTP/HTTP/HTTPS/FTP/FTPS Servers
For users that would like to use remote upgrading without a local TFTP/HTTP/HTTPS/FTP/FTPS server, Grand stream 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:
https://www.solarwinds.com/products/freetools/free_tftp_server.aspx
https://pjo2.github.io/tftpd64/
Instructions for local firmware upgrade via TFTP:
- Unzip the firmware files and put all of them in the root directory of the TFTP
- Connect the PC running the TFTP server and the phone to the same LAN
- 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.
- Start the TFTP server and configure the TFTP server in the phone’s web configuration
- Configure the Firmware Server Path to the IP address of the
- Save and Apply the changes and reboot the HT81x
End users can also choose to download a free HTTP server from https://httpd.apache.org/ or use a Microsoft IIS web server.
Firmware and Configuration File Prefix and Postfix
Firmware Prefix and Postfix allow the device to download the firmware name with the matching Prefix and Postfix. This makes it possible to store all the firmware with different version in one single directory. Similarly, Config File Prefix and Postfix allow the 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.
Firmware File Prefix and Postfix
Managing Automatic Upgarde
When “Automatic Upgrade” is set “Check” the auto check will be done in the minute specified in this field. If set to “Every day in 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 periodically to 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
Automatic Upgrade
Managing Device using GDMS Cloud
The GDMS Device Management System is a cloud solution from Grandstream that facilitates the provisioning and management of Grandstream devices, including the HT8xx ATAs.
The platform enables users to centralize the control and management of multiple HT8xx devices, deployed across various locations, on a single interface. It provides functionalities to upgrade, add, configure, and monitor HT8xx V2 devices from one centralized dashboard.
For more details on the supported HT8xx V2 models and their deployment to the GDMS platform, refer to the following guide: GDMS Unified Communications – User Guide.
If you don’t have a GDMS account yet, visit the following website to create one: GDMS.
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, HTTP/HTTPS or FTP/FTPS. The Config Server Path is the TFTP, HTTP/HTTPS or FTP/FTPS 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 1 to 5 (Could be extended in the future) digit numeric numbers. i.e., P30 is associated with the “NTP Server” in the Web GUI? System Settings?Time and Language?Time Zone?NTP Server. For a detailed parameter list, please refer to the corresponding firmware release configuration template.
When the HT81x V2 boots up or reboots, it will send a request to download the xml file named “cfgxxxxxxxxxxxx.xml” followed by the binary file named “cfgxxxxxxxxxxxx”, 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<Model>.xml file and then download cfg.xml. The configuration file name should be in lower case letters.
HT818 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: <option 67 bootfile>
Step 2: cfg<MAC>.xml →cfg<MAC>→cfg<Model>.xml →cfg.xml
Notes:
- The Only acceptable Config file formats to be used when provisioning are XML or
- Make sure the MAC header on the Config file is the provisioned device’s MAC address or you can remove the header completely.
- When the <option 67 bootfile> is downloaded from the server, the cfg<MAC>.xml is not
For more details on XML provisioning, please refer to: https://documentation.grandstream.com/knowledge-base/sip-device-provisioning-guide/
