CALL OPERATIONS

Placing a Phone Call

To make the outgoing calls using your HT818

  1. Pick up the handset of the connected phone.
  2. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or
  3. Dial the number directly and press # (Use # as dial key” must be configured in web configuration).

Examples:

  1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds.
  2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers.

Note:

When placing the analog phone that is connected to the FXS port off hook, the dial tone will be played even if the sip account is not registered. If users prefer the busy tone to be played instead, the following configuration need to be made:

  • “Play Busy Tone When Account is unregistered” need to be set to YES under advanced settings.
  • “Outgoing call without registration” need to be set to NO under Profile x settings.

Direct IP Calls

Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy.

Elements necessary to completing a Direct IP Call:

  • Both HT818 and other VoIP Device, have public IP addresses, or
  • Both HT818 and other VoIP Device are on the same LAN using private IP addresses, or
  • Both HT818 and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).

The HT818 support two ways to make Direct IP Calling:

Using IVR

  1. Pick up the analog phone then access the voice menu prompt by dialing “***”
  2. Dial “47” to access the direct IP call menu
  3. Enter the IP address after the dial tone and voice prompt “Direct IP Calling”

Using Star Code

  1. Pick up the analog phone then dial “*47”
  2. Enter the target IP address.

Note: No dial tone will be played between step 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 seconds. 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.

Call Waiting

The call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled.

To toggle between incoming call and current call, you need to press the “flash” button the first call is placed on hold.

Press the “flash” button to toggle between the active calls.

  1. On the phone A presses FLASH to hear the dial tone.
  2. Phone A dials the phone C’s number followed by # (or wait for 4 seconds).
  3. If phone C answers the call, phones A and C are in conversation. Then A can hang up to complete transfer.
  4. If phone C does not answer the call, phone A can press “flash” to resume call with phone B.

When attended transfer fails and A hangs up, the HT818 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 HT818 support 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 (HT818) wants to bring third phone C into conference:

  1. Phone A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone.
  2. Phone A dials C’s number then # (or wait for 4 seconds).
  3. If phone C answers the call, then A presses FLASH to bring B, C in the conference.
  4. If phone C does not answer the call, phone A can press FLASH back to talk to phone B.
  5. If phone A presses FLASH during conference, the phone C will be dropped out.
  6. 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

In order to call back to the latest incoming number.

  1. Pick up the handset of the connected phone (Off-hook).
  2. After hearing the dial tone, input “*69”.
  3. 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 HT818 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 HT818 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 HT818 indicates new voice mail messages using Phone LEDs and Stutter Tone.

The Phone LEDs on HT818 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.

Accessing VM

To retrieve the new voice mail messages received, please refer to following steps:

  1. Pick up the handset of the connected phone (stutter tone will be played).
  2. Press *** (press the star key three times) to access the IVR menu and wait until you hear “Enter the menu option “.
  3. Press 86 and enter your configured password (if exist) to access your voice mail menu.

Flash Digit Control

If the option “Flash Digit Control” is enabled on web UI, call operations will require different steps as follows:

  • Call Hold:

Assume that the call is established between phone A and B.

The phone A received a call from C, then it held B to answer C.

Press the “Flash + 1” to hang up the current call (A – C) and resume call on hold (B).

Or press “Flash + 2” to hold current call (A – C) and resume call on hold (B).

  • Attended transfer:

Assume that the call is established between phone A and B. The phone A wants to attend transfer phone B to phone C:

  1. On the phone A presses FLASH to hear the dial tone.
  2. Phone A dials the phone C’s number followed by # (or wait for 4 seconds).
  3. If phone C answers the call, phones A and C are in conversation. Then A can press “Flash + 4” to complete transfer.
  • 3-Way Conferencing:

Assume that the call is established, and phone A and B are in conversation. Phone A(HT801/HT802) wants to bring third phone C into conference:

  1. Phone A presses Flash (on the analog phone, or Hook Flash for old model phones) to get a dial tone.
  2. Phone A dials C’s number then # (or wait for 4 seconds).
  3. When phone C answers the call, then A can press “Flash +3” to bring B, C in the conference.
Note

Additional Flash digit events have been added on the latest firmware version 1.0.43.10

NAT Settings

If you plan to keep the HT818 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 HT818 support the following DTMF mode:

• DTMF in-audio

• DTMF via RTP (RFC2833)

• DTMF via SIP INFO

Set priority of DTMF methods according to your preference. This setting should be based on your server DTMF setting.

Preferred Vocoder (Codec)

The HT818 support following voice codecs. On Profile pages, choose the order of your favorite codecs:

  • PCMU/A (or G711µ/a)
  • G729 A/B
  • G723.1
  • G726
  • iLBC
  • OPUS
  • G722

UPGRADING AND PROVISIONING

The HT818 can be upgraded via TFTP/HTTP/HTTPS/FTP/FTPS by configuring the URL/IP Address for the TFTP/HTTP/HTTPS/FTP/FTPS server and selecting a download method. Configure a valid URL for TFTP, HTTP/HTTPS or FTP/FTPS; the server name can be FQDN or IP address.

Examples of valid URLs:

firmware.grandstream.com

fw.ipvideotalk.com/gs

Firmware Upgrade procedure

  5. Make sure to check “Always Check for New Firmware”.
  6. Update the change by clicking the “Apply” button at the bottom of the page. Then “Reboot” or power cycle the HT818 to update the new firmware.
Firmware Upgrade Page

Upgrading via Local Directory

  1. Download the firmware file from Grandstream web site
  2. Unzip it and copy the file in to a folder in your PC
  3. From the HT818 web interface (Advanced Settings page) you can browse your hard drive and select the folder you previously saved the file (HT8xfw.bin)
  4. Click “Upload Firmware” and wait few minutes until the new program is loaded.

Always check the status page to see that the program version has changed.

Upgrading via Local TFTP/HTTP Servers

For users that would like to use remote upgrading without a local TFTP/HTTP/FTP 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 a free TFTP, HTTP or FTP 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 HT818.

End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use Microsoft IIS web server.

Also, users can download a free FTP server from https://filezilla-project.org/.

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 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

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 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 HT818 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.xml file. The configuration file name should be in lower case letters.

Notes:

  1. The Only acceptable Config file formats to be used when provisioning are XML or binary.
  2. Make sure the MAC header on the Config file is the provisioned device’s MAC address or you can remove the header completely.

RESTORE FACTORY DEFAULT SETTINGS

Restoring the Factory Default Settings will delete all configuration information on the phone. Please backup or print all the settings before you restore to the factory default settings.
