Five Success Tips when using the Voice Prompt
1. “*” shifts down to the next menu option
2. “#” returns to the main menu
3. “9” functions as the ENTER key in many cases to confirm or toggle an option
4. All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP
address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26
should be key in like 192168000026. No decimal is needed).
5. Key entry cannot be deleted but the phone may prompt error once it is detected
PLACING A PHONE CALL
PHONE OR EXTENSION NUMBERS
1. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or
FIRMWARE VERSION 1.0.5.8
52
HT70X USER MANUAL
Page 18 of
2. 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.
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:
1. Both HT70X and other VoIP Device, have public IP addresses, or
2. Both HT70X and other VoIP Device are on the same LAN using private IP addresses, or
3. Both HT70X and other VoIP Device can be connected through a router using public or private IP
addresses (with necessary port forwarding or DMZ).
HT70X supports two ways to make Direct IP Calling:
Using IVR
1. Pick up the analog phone then access the voice menu prompt by dial “***”
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.
Destination ports can be specified using “*” (encoding for “:”) followed by the port number.
Examples of Direct IP Calls:
FIRMWARE VERSION 1.0.5.8

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:

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”. You
cannot make direct IP calls between FXS1 to FXS2 since they are using same IP.
CALL HOLD
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
Call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle
between incoming call and current call by pressing the “flash” button. First call is placed on hold. Press
the “flash” button to toggle between two active calls.
CALL TRANSFER
BLIND TRANSFER
Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:
3. Caller A presses FLASH on the analog phone to hear the dial tone.
4. Caller A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds)
5. Caller A will hear the dial tone. Then, A can hang up.
NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page.
ATTENDED TRANSFER
Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C:
1. Caller A presses FLASH on the analog phone for dial tone.

complete transfer.
4. If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.
NOTE: When Attended Transfer fails and A hangs up, the HT70X 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 HT701/702/704 supports Bellcore style 3-way Conference.
Instructions for 3-way conference:
Assume that call party A and B are in conversation. Caller A(HT70X) wants to bring third Caller C into
conference:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone.
2. A dials C’s number then # (or wait for 4 seconds).
3. If C answers the call, then A presses FLASH to bring B, C in the conference.
4. If C does not answer the call, A can press FLASH back to talk to B.
5. If A presses FLASH during conference, C will be dropped out.
6. If 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.
FAX SUPPORT
HT70X supports FAX in two modes: 1) T.38 (Fax over IP) and 2) fax pass through. T.38 is the preferred
method because it is more reliable and works well in most network conditions. If the service provider
supports T.38, please use this method by selecting Fax mode to be T.38 (default). If the service provider
does not support T.38, pass-through mode can be used.

embedded STUN client will detect if and what type of firewall/NAT. If the detected NAT
is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the HT70X will use its
mapped public IP address and port in all of its SIP and SDP messages.
If the NAT Traversal field is set to “Yes” with no specified STUN server, the HT70X will
periodically (every 20 seconds or so) send a blank UDP packet (with no payload data)
to the SIP server to keep the “hole” on the NAT open.

CONFIGURATION THROUGH A CENTRAL SERVER
Grandstream HT70X can be automatically configured from a central provisioning system.
When HT70X boots up, it will send TFTP or HTTP/HTTPS requests to download configuration files,
“cfg000b82xxxxxx” and “cfg00082xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the
HT70X. 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 or HTTP/HTTPS from the central server. A service
provider or an enterprise with large deployment of HT70X 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 enhanced (NAT
friendly) TFTP or HTTP (thus no NAT issues) 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 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

Software upgrade can be done via either TFTP or HTTP. The corresponding configuration settings are in
the ADVANCED SETTINGS configuration page.
FIRMWARE UPGRADE THROUGH TFTP/HTTP/HTTPS
To upgrade via TFTP or HTTP/HTTPS, the “Firmware Upgrade and Provisioning upgrade via” field needs
to be set to TFTP HTTP or HTTPS, respectively. “Firmware Server Path” needs to be set to a valid URL
of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples
of some valid URL.
e.g. firmware.mycompany.com:6688/Grandstream/1.0.5.2
e.g. firmware.grandstream.com
NOTES:

Firmware upgrade server in IP address format can be configured via IVR. Please refer to the
CONFIGURATION GUIDE section for instructions. If the server is in FQDN format, it must be set
via the web configuration interface.

Grandstream recommends end-user use the Grandstream HTTP server. Its address can be
found at http://www.grandstream.com/support/firmware . Currently the HTTP firmware server IP
address is firmware.grandstream.com. For large companies, we recommend to maintain their
own TFTP/ HTTP/HTTPS server for upgrade and provisioning procedures.

Once a “Firmware Server Path” is set, user needs to update the settings and reboot the device. If
the configured firmware server is found and a new code image is available, the HT70X will
attempt to retrieve the new image files by downloading them into the HT70X’s SRAM. During this
stage, the HT70X’s LEDs will blink until the checking/downloading process is completed. Upon
verification of checksum, the new code image will then be saved into the Flash. If
TFTP/HTTP/HTTPS fails for any reason (e.g. TFTP/HTTP/HTTPS server is not responding, there
are no code image files available for upgrade, or checksum test fails, etc), the HT70X will stop the
TFTP/HTTP/HTTPS process and simply boot using the existing code image in the flash.

Firmware upgrade may take as long as 15 to 30 minutes over Internet, or just 5 minutes if it is
performed on a LAN.

environment if possible. For users who do not have a local firmware upgrade server,
Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade.

Grandstream’s latest firmware is available at http://www.grandstream.com/support/firmware .
Oversea users are strongly recommended to download the binary files and upgrade firmware
locally in a controlled LAN environment.
Note:
Alternatively, the user can upload the firmware single file from his/her computer using a local
directory. For more instructions see below. Also the user can download a free TFTP or HTTP server and
conduct local firmware upgrade. A free windows version TFTP server is available for download from
http://support.solarwinds.net/updates/New-customerFree.cfm.
Our latest official release can be
downloaded from http://www.grandstream.com/support/firmware .
INSTRUCTIONS FOR UPLOAD FROM 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 HT70X web interface (Advanced Settings page) you can browse your hard drive and
select the folder you previously saved the file (ht70xfw.bin)
4- Click “Upload Firmware” and wait few minutes until the new program is loaded.
Note: Always check the status page to see that the program version has changed.
INSTRUCTIONS FOR LOCAL FIRMWARE UPGRADE USING TFTP SERVER:
1. Unzip the file and put all of them under the root directory of the TFTP server.
2. Put the PC running the TFTP server and the HT701 device in the same LAN segment.
3. Please go to File -> 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, in the phone’s web configuration page
5. Configure the Firmware Server Path with the IP address of the PC
6. Update the change and reboot the unit

End users can also choose to download the free HTTP server from http://httpd.apache.org/ or use
Microsoft IIS web server.
CONFIGURATION FILE DOWNLOAD
Grandstream SIP Device can be configured via Web Interface as well as via Configuration File through
TFTP or HTTP/HTTPS. “Config Server Path” is the TFTP or HTTP/HTTPS server path for configuration
file. It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can
be 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 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.
When a Grandstream device boots up or reboots, it will issue a request for a configuration file
“cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. In
addition, device will also requests a XML configuration file “cfgxxxxxxxxxxxx.xml”. If the download of
“cfgxxxxxxxxxxxx.xml” is not successful, the provision program will issue a request for a generic
c o nf i g ur a t i o n f i l e “ c f g. x m l” . C o nf i g ur a t i o n f il e n am e s h o u l d b e i n l o we r c a s e l e t t er s .
For more details on XML provisioning, please refer to:
http://www.grandstream.com/general/gs_provisioning_guide_public.pdf
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 in the day specified in this field. This allows the device
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.
