Grandstream Networks, Inc. HT-701 User Manual Page 11 of 31
Firmware Version 1.0.0.17 Last Updated: 02/2012
“Device not registered” This prompt will be played immediately after off hook If the device is
not register and the option “Outgoing Call without Registration” is in
NO
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 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 can not 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
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. [phone]), 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 HT701 and other VoIP Device, have public IP addresses, or
2. Both HT701 and other VoIP Device are on the same LAN using private IP addresses, or
3. Both HT701 and other VoIP Device can be connected through a router using public or private IP
addresses (with necessary port forwarding or DMZ).
HT701 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.

Grandstream Networks, Inc. HT-701 User Manual Page 12 of 31
Firmware Version 1.0.0.17 Last Updated: 02/2012
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:
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 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 confirm tone. Then, A can hang up.
NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page.
Caller A can place a call on hold and wait for one of three situations:
1. A quick confirmation tone (similar to call waiting tone) followed by a dial-tone. This indicates the
transfer is successful (transferee has received a 200 OK from transfer target). At this point, Caller
A can either hang up or make another call.
2. A quick busy tone followed by a restored call (on supported platforms only). This means the
transferee has received a 4xx response for the INVITE and we will try to recover the call. The busy
tone is just to indicate to the transferor that the transfer has failed.
3. Continuous busy tone. The phone has timed out.
Note: continuous busy tone does not indicate the transfer has been successful, nor does it indicate
the transfer has failed. It often means there was a failure to receive second NOTIFY – check firmware
for most recent release.

Firmware Version 1.0.0.17 Last Updated: 02/2012
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.
2. Caller A then dials Caller C’s number followed by # (or wait for 4 seconds).
3. If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to
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 HT701 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 supports Bellcore style 3-way Conference.
Instructions for 3-way conference:
Assume that call party A and B are in conversation. Caller A(HT701) 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 Hangup” 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
HT701 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.

.
Configuring the HT701 Via Web Browser
HT701 has an embedded Web server that will respond to HTTP GET/POST requests. It also has
embedded HTML pages that allow users to configure the HT701 through a web browser such as
Microsoft’s IE, AOL’s Netscape or Mozilla Firefox installed on Windows or Unix OS. (Macintosh OS is not
included).
Access the Web Configuration Menu
1. Find the IP address of the HT701 using voice prompt menu option 02.
2. Open a web browser, type the IP address. You will see the log in page of the device.
Note:
•The IVR announces 12 digits IP address, you need to strip out the leading “0” in the IP address.
For ex. IP address: 192.168.001.014, you need to type in http://192.168.1.14 in the web browser.
Once the HTTP request is entered and sent from a web browser, the user will see a log-in screen. There
are two default passwords for the login page:

Grandstream Networks, Inc. HT-701 User Manual Page 16 of 31
Firmware Version 1.0.0.17 Last Updated: 02/2012
User Level: Password: Web pages allowed:
End User Level 123 Only Status and Basic Settings
Administrator Level admin Browse all pages
The password is case sensitive with maximum length of 25 characters. The factory default password for
End User and administrator is “123” and “admin” respectively. Only an administrator can access the
“ADVANCED SETTING”, “FXS PORTs” configuration pages. Please reference the GUI pages using the
following link: http://www.grandstream.com/products/ht_series/HT701/documents/HT701_gui.zip .
NOTE: If you cannot log into the configuration page by using the default password, please check with the
VoIP service provider. It is most likely the VoIP service provider has provisioned the device and configured
for you therefore the password has already been changed.
Important Settings
The end-user must configure the following settings according to the local environment. NOTE: Most
settings on the web configuration pages are set to the default values.
NAT Settings
If you plan to keep the gateway within a private network behind a firewall, we recommend using STUN
Server. The following three (3) 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 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 Profile web pages)
Set this to Yes when gateway is behind firewall on a private network.
DTMF Methods
DTMF Settings are in FXS portX pages.
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 HT701 supports a broad range of voice codecs. Under Profile web pages, choose your preferred
order of different codecs:
PCMU/A (or G711µ/a)

Grandstream Networks, Inc. HT-701 User Manual Page 17 of 31

IP Address There are two modes to operate the HT701:
DHCP mode: all the field values for the Static IP mode are not used (even though they
are still saved in the Flash memory.) The HT701 acquires its IP address from the first
DHCP server it discovers from the LAN it is connected. Using the PPPoE feature: set the
PPPoE account settings. The HT701 will establish a PPPoE session if any of the PPPoE
fields is set.
Static IP mode: configure the IP address, Subnet Mask, Default Router IP address,
DNS Server 1 (primary), DNS Server 2 (secondary) fields. These fields are set to zero by
default.
DHCP hostname Default is blank. This option specifies the name of the client. This field is optional but may
be required by some Internet Service Providers.
DHCP domain Default is blank. This option specifies the domain name that client should use when
resolving hostnames via the Domain Name System.
