5Basic Operations
5.1 Get Familiar with Voice Prompt
HandyTone-496 stores a voice prompt menu (Interactive Voice Response or IVR) for quick browsing
and simple configuration. Currently, the voice prompt menu and the LED button are designed for FXS
port 1 only.
To enter this voice prompt menu, simply pick up the phone and press the button on the HandyTone-
496 or pick up the phone and dial “***”. The following table shows how to use the voice prompt menu
to configure the device.
Menu Voice Prompt 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, 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
04 “Gateway “ + 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”.)
99 “RESET” Enter “9” to reboot the device; or
Enter encoded MAC address to restore factory
default setting (For details, see section 8.)
“Invalid Entry” Automatically returns to main menu
NOTES:

HandyTone-496 User Manual Grandstream Networks, Inc.
11
•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. 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
To make a phone or extension number call:
a) Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”). Or
b) Dial the number 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, 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 HandyTone ATA and other VoIP Device(i.e., another HandyTone ATA or Budgetone SIP
phone or other VoIP unit) have public IP addresses, or
•Both HandyTone ATA and other VoIP Device are on the same LAN using private IP addresses,
or
•Both HandyTone ATA and other VoIP Device can be connected through a router using public
or private IP addresses (with necessary port forwarding or DMZ).

HandyTone-496 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-496,
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 192.168.0.160, the dialing convention is
Voice Prompt with option 47, then 192168000160
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.
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.
5.2.3 Call Hold
While in conversation, pressing the “flash” button on the attached phone 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.
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
Assuming that call party A and B are in conversation. A wants to Blind Transfer B to C:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a 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: “Enable Call Feature” has to be set to “Yes” in web configuration page.

HandyTone-496 User Manual Grandstream Networks, Inc.
13
A can hold on to the phone and wait for 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
Assuming 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, or Hook Flash for old model phones) to get a dial tone
2. A then dial C’s number then # (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, if A hangs up, the HandTone-496 will ring user A 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
HandyTone-496 supports 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.

will switch to a new channel for a new call.
5.4 Fax
HandyTone-496 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. If the service

HandyTone-496 User Manual Grandstream Networks, Inc.
15
provider does not support T.38, pass-through mode may be used. To send or receive faxes in fax pass
through mode, user is recommended to select all the Preferred Codecs to be PCMU/PCMA.
