5Basic Operations
5.1 Get Familiar with Voice Prompt
HandyTone-386 has a stored voice prompt menu for quick browsing and simple configuration.
Currently, the voice prompt menu and the LED button is designed for FXS port 1 ONLY.
To enter this voice prompt menu, simply press the button or “***” from the analog phone.
Menu Voice Prompt User’s Options
Main Menu “Enter a Menu Option” Enter “*” for the next menu option
Enter “#” to return to the main menu
Enter 01 – 06, 47, 86 or 99 Menu option
01 “DHCP Mode”,
“Static IP Mode” Enter ‘9’ to toggle the selection If user selects “Static IP Mode”, user need
configure the all IP address information
through menu 02 to 05. If user selects
“Dynamic IP Mode”, the device will retrieve
all IP address information from DHCP server
automatically when user reboots the device.
02 “IP Address “ + IP address The current WAN IP address is announced
Enter 12-digit new IP address if in Static IP
Mode.
03 “Subnet “ + IP address Same as menu 02

05 “DNS Server “ + IP address Same as menu 02
06 “TFTP Server “ + IP address Same as menu 02
47 “Direct IP Calling” When entered, user will be prompted a dial
tone, dial a 12-digit IP address to make a direct
IP call.
(For details, see “4.2.2 Make a Direct IP
Call”.)
86 “Voice Messages Pending”
“No Voice Messages” If there are voice messages, user can dial “9” and dial pre-configured phone number to
retrieve voice message.
99 “RESET” Enter “9” to reboot the device; or
Enter MAC address to restore factory default
setting (For details, see section 8.)
“Invalid Entry” Automatically return to Main Menu

HandyTone-386 User Manual Grandstream Networks, Inc.
11
NOTE:
•Once the button is pressed, it enters the voice prompt main menu. If the button is pressed again,
while it is already in the voice prompt menu, it jumps to “Direct IP Call” option and a dial
tone is prompted
•“*” shifts down to the next menu option
•“#” returns to the main menu
•“9” functions as the ENTER key in many cases to confirm an option
•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 (like 192.168.0.26
should be key in like 192168000026, no dot needed while input). Once all of the digits are
collected, the input will be processed.
•Key entry can not be deleted but the phone may prompt error once it is detected
5.2 Make Phone Calls
5.2.1 Calling phone or extension numbers
There are currently two methods to make an extension number call:
a) Dial the numbers directly and wait for 4 (default) seconds.
b) Dial the numbers directly, and press # (assuming that “use # as dial key is selected in web
configuration).
Examples:
•To dial another extension on the same proxy, such as 1008, simply pick up the attached phone,
dial 1008 and then press the # or wait for 4 seconds.
•To dial a PSTN number such as 6266667890, you might need to enter in some prefix number
followed by the phone number. Please check with your VoIP service provider to get the
information. If you phone is assigned with a PSTN-like number such as 6265556789, most
likely you just follow the rule to dial 16266667890 as if you were calling from a regular analog
phone of North America, then followed by pressing # or wait for 4 seconds.
5.2.2 Direct IP calls
Direct IP calling allows two parties, that is, a HandyTone with an analog phone and another VoIP
Device, to talk to each other in an ad hoc fashion without a SIP proxy. This kind of VoIP calls can be
made between two parties if:
•Both HT386 and other VoIP Device(i.e., another HandyTone ATA or Budgetone SIP phone or
other VoIP unit) have public IP addresses, or
•Both HT386 and other VoIP Device are on the same LAN using private IP addresses, or
•Both HT386 and other VoIP Device can be connected through a router using public or private
IP addresses (with necessary port forwarding or DMZ).

HandyTone-386 User Manual Grandstream Networks, Inc.
12
To make a direct IP call, first pick up the analog phone or turn on the speakerphone on the analog
phone, then access the voice menu prompt by dial “***” or press the button on the HandyTone-286,
and dials “47” to access the direct IP call menu. User will hear a voice prompt “Direct IP Calling” and
a dial tone. Enter a 12-digit target IP address to make a call. Destination ports can be specified by
using “*4” (encoding for “:”) followed by the port number.
Examples:
If the target IP address is 192.168.0.10, the dialing convention is
Voice Prompt with option 47, then 192 168 000 010
followed by pressing the “#” key if it is configured as a send key or wait for more than 5 seconds.
If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:
Voice Prompt with option 47, then 192168001020*45062 followed by pressing the “#” key if it is
configured as a send key or wait for 4 seconds.
NOTE:
•When doing direct IP call, the “Use Random Port” should set to “NO”.
•You can NOT make direct IP calls between FXS1 to FXS2 since they are using same IP.
5.2.3 Call Hold
While in conversation, pressing the “flash” button on the attached analogue phone (if the phone has
that button) will put the remote end on hold. Pressing the “flash” button again will release the
previously held party and the bi-directional media will resume. If no “flash” button, then on-off hook
quickly (hook flash) will do the same thing but also risk of losing call if the time is not short enough.
5.2.4 Call Waiting
If call waiting feature is enabled, while the user is in a conversation, he will hear a special stutter tone
if there is another incoming call. User can press the flash button to put the current call party on hold
and switch to the other call. Pressing flash button toggles between two active calls.
5.2.5 Call Transfer
5.2.5.1 Blind Transfer
Assume that call party A and B are in conversation. A wants to Blind Transfer B to C:
1. A press FLASH on the analog phone to hear the dial tone.
2. Then A dials *87 then dials C’s number, and then #(or wait for 4 seconds)
3. A can hang up.
NOTE:

HandyTone-386 User Manual Grandstream Networks, Inc.
13
•“Enable Call Feature” has to be set to “Yes” in web configuration page.
A can hold on to the phone and await one of the three following behaviors:
•A quick confirmation tone (temporarily using the call waiting indication tone) followed by a
dial tone. This indicates the transfer is successful (transferee has received a 200 OK from
transfer target). At this point, A can either hang up or make another call.
•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.
•Busy tone keeps playing. This means we have failed to receive the second NOTIFY from the
transferee and decided to time out. Note: this does not indicate the transfer has been
successful, nor does it indicate the transfer has failed. When transferee is a client that does not
support the second NOTIFY (such as our own earlier firmware), this will be the case. In bad
network scenarios, this could also happen, although the transfer may have been completed
successfully.
5.2.5.2 Attended Transfer
Assume that call party A and B are in conversation. A wants to Attend Transfer B to C:
1. A presses FLASH on the analog phone to get a dial tone
2. A then dial C’s number followed by # (or wait for 4 seconds).
3. If C answers the call, A and C are in conversation. Then A can hang up to complete transfer.
4. If C does not answer the call, A can press “flash” back to talk to B.
NOTE:
•When Attended Transfer failed and A hang up, the HandyTone- 386 will ring user A back again
to remind A that B is still on the call. A can pick up the phone to restore conversation with B.
5.2.6 3-way Conferencing
5.2.6.1 Star Code Style 3-way Conference
Assuming that call party A and B are in conversation. A wants to bring C in a conference:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial
tone.
2. A dials *23 then C’s number then # (or wait for 4 seconds).
3. If C answers the call, then A press “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.
5.2.6.2 Bellcore Style 3-way Conference

HandyTone-386 User Manual Grandstream Networks, Inc.
14
Bellcore style 3-way conference is also supported. To do this, user needs to enable “Use Bell-style 3-
way Conference” in FXS1 or FXS2 web configuration.
Assuming that call party A and B are in conversation. A wants to bring C in a 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 press “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.
5.2.7 PSTN Pass Through
HandyTone-386 supports PSTN pass through on FXS port 1. User can make and receive PSTN calls
with attached analog phone in Phone 1 port. Phone 2 port (or FXS port 2) does NOT have this feature.
•To receive PSTN calls, simply make phone off hook when the analog phone rings.
•To make a PSTN call, simply press the PSTN access code (*00 is default, or any number
configured in web configuration page) to switch to the PSTN line and get dial tone, then dial
the number.

a pass through jack. The user will be able to use the analog phone for PSTN calls directly without press
the access code.
5.4 FAX Support
HandyTone 386 supports FAX in two modes: T.38 (Fax over IP) and 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 may be used. To send or receive faxes in
fax pass through mode, users must select all the Preferred Codecs to be PCMU/PCMA (G.711-u/a).
