5.2 Make Phone Calls
5.2.1 Calling phone or extension numbers
There are currently two methods to make an extension number call:
1) Dial the extension number directly and wait for 5 seconds.
2) Dial the numbers directly, and press # (Assuming that “use #” as dial key is
selected in web configuration. For detail, see section 5.2 configure Handytone
using web browser).
Other functions available during the call are call-waiting/flash, call-transfer, and callforwarding.
5.2.2 Direct IP calls
Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a
SIP proxy. VoIP calls can be made between two phones, if:
both HandyTone ATA and other VOIP Devices(i.e., another HandyTone ATA or
other IP phone) have public IP addresses, or
both HandyTone ATA and other VOIP Devices(i.e., another HandyTone ATA or
other IP phone) are on a same LAN using private or public IP addresses, or
both HandyTone ATA and other VOIP Devices(i.e., another HandyTone ATA or
other IP phone) can be connected through a router using public or private IP
addresses.
To make a direct IP calling, 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 HT286, and dials “47” to access the direct IP call menu. User will hear a
voice prompt “Direct IP Calling” and a dial tone. Then user dials the 12-digit target IP
address to make a call.
If there is a user name part in the target address, such as username@192.168.10.123,
encode the user name part (see the following encoding scheme table), followed by *3
(encoding for “@”) and then followed by the 12-digit target IP address. Destination
ports can also be specified using *4 (encoding for “:”) followed by the encoded port
number.
The follow is a table of the encoding scheme for the most commonly used characters:

The rule of thumb to remember these encoding is: “a” is the first letter on button “1” so
its encoding is “11”. “b” is the 2
rd
the 3
letter on button “1” and its encoding is “13”. Likewise, “d” is the first letter on
button “2” and its encoding is “21”. This pattern and rule applies to all other alphabetic
encoding.
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 is it is configured as a send key or wait for more than 5
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 is it is configured as a send key or wait for 5 seconds.
If the target address is john@192.168.1.100:5062
Voice Prompt with option 47, then 51634262*3192168001100*45062
followed by pressing the “#” key is it is configured as a send key or wait for 5 seconds.

The password is case sensitive and the factory default password is lower case ‘admin’.
6.2.2 Configuration Menu
After the correct password is entered in the login screen, the embedded Web server
inside the IP phone will respond with the Configuration Menu screen, which is
explained in details below.
The definitions for all the configuration parameters in the Configuration Menu are:
Information
Field
This field shows basic information of the device, including the
MAC address, the model, and the software version.
Password
IP Address
SIP Server
This contains the password to access the Web Configuration Menu.
This field is case sensitive.
There are 2 modes under which the IP phone can operate:
- If DHCP mode is enabled, then all the field values for the Static IP
mode are not used (even though they are still saved in the Flash
memory) and the IP phone will acquire its IP address from the first
DHCP server it discovers on the LAN it attaches to.
- If Static IP mode is selected, then the IP address, Subnet Mask,
Default Router IP address, DNS Server 1 (primary), DNS Server 2
(secondary) fields will need to be configured. These fields are reset
to zero by default.
This field contains the URI string or the IP address (and port, if
different from 5060) of the SIP proxy server. e.g., the following are
some valid examples: sip.my-voip-provider.com, or sip:mycompany-sip-server.com, or 192.168.1.200:5066
- 15 -
HandyTone 286 User Manual Grandstream Networks, Inc.
Outbound Proxy
SIP User ID
SIP User ID is
Phone Number
SIP Login ID
This field contains the URI string or the IP address (and port, if
different from 5060) of the outbound proxy. If there is no outbound
proxy, this field SHOULD be left blank. If not blank, all outgoing
requests will be sent to this outbound proxy.
This field contains the user part of the SIP address for this phone.
e.g., if the SIP address is: sip:my_user_id@my_provider.com, then
the SIP User ID is: my_user_id. Please do NOT include the
preceding “sip:” scheme or the host portion of the SIP address in
this field.
If the IP phone has an assigned PSTN telephone number, then this
field will be set to “Yes”. Otherwise, set it to “No”. If “Yes” is set,
a “user=phone” parameter will be attached to the “From” header in
SIP request.
This field contains the login ID used for SIP authentication.
Typically, this is the account number on an SIP server for this IP
phone. It can be the same as or different from the above SIP User
ID, depending on whether a separate account ID is used for
authentication.
SIP Password
This field contains the password used for SIP authentication. It is
used together with the above SIP Login ID

Preferred
Vocoder
G723 Rate:
iLBC frame
size
iLBC payload
type
The BudgeTone IP phone supports up to 7 different vocoder types
including G711-ulaw (PCMU), G711-alaw (PCMA), G723,
G729A/B, G726-32 (ADPCM), G728, and iLBC. Depending on the
product model, some of these vocoders may not be provided in
standard release.
A user can configure vocoders in a preference list that will be
included with the same preference order in SDP message. The first
vocoder in this list can be entered by choosing the appropriate option
in “Choice 1”. Similarly, the last vocoder in this list can be entered
by choosing the appropriate option in “Choice 7”.
This defines the encoding rate for G723 vocoder. By default, 6.3kbps
rate is chosen.
This defines the size of the iLBC codec frame. The default setting is
20ms.
This defines the iLBC payload type. The default setting is 96.
Silence
Suppression
This controls the silence suppression/VAD feature of G723 and
G729. If set to “Yes”, when a silence is detected, small quantity of
VAD packets (instead of audio packets) will be sent during the
period of no talking. If set to “No”, this feature is disabled.
- 18 -
HandyTone 286 User Manual Grandstream Networks, Inc.
Voice Frames
per TX
This field contains the number of voice frames to be transmitted in a
single packet. When setting this value, the user should be aware of
the requested packet time (used in SDP message) as a result of
configuring this parameter. This parameter is associated with the
first vocoder in the above vocoder Preference List or the actual used
payload type negotiated between the 2 conversation parties at run
time.
e.g., if the first vocoder is configured as G723 and the “Voice
Frames per TX” is set to be 2, then the “ptime” value in the SDP
message of an INVITE request will be 60ms because each G723
voice frame contains 30ms of audio. Similarly, if this field is set to
be 2 and if the first vocoder chosen is G729 or G711 or G726, then
the “ptime” value in the SDP message of an INVITE request will be
20ms.
If the configured voice frames per TX exceeds the maximum
allowed value, the phone will use and save the maximum allowed
value for the corresponding first vocoder choice. The maximum
value for PCM is 10(x10ms) frames; for G726, it is 20 (x10ms)
frames; for G723, it is 32 (x30ms) frames; for G729/G728, 64
(x10ms) and 64 (x2.5ms) frames respectively.
Layer 3 QoS
Layer 2 QoS
Use DNS SRV
User ID is
phone number
SIP
Registration
Unregister On
Reboot
This field defines the layer 3 QoS parameter which can be the value
used for IP Precedence or Diff-Serv. Default value is 48
This setting includes two fields. The 802.1Q/VLAN Tag contains the
value used for layer 2 VLAN tag. Default setting is blank. And
802.1p priority value contains the value of the priority value.
This parameter controls whether the IP phone supports the DNS
SRV route function.
If the HandyTone ATA has an assigned PSTN telephone number,
then this field will be set to “Yes”. Otherwise, set it to “No”. If
“Yes” is set, a “user=phone” parameter will be attached to the
“From” header in SIP request.
This parameter controls whether the IP phone needs to send
REGISTER messages to the proxy server. The default setting is
“Yes”.
Default is No. If set to yes, the SIP user will be unregistered on
reboot.
- 19 -
HandyTone 286 User Manual Grandstream Networks, Inc.
Registration
Expiration
Early Dial
Dial Plan
Prefix
This parameter allows the user to specify the time frequency (in
minutes) the phone will refresh its registration with the specified
registrar. The default interval is 60 minutes (or 1 hour). The maximum
interval is 65535 minutes (about 45 days).
This parameter controls whether the phone will attempt to send an
early INVITE each time a key is pressed when a user dials a number.
If set to “Yes”, an INVITE is sent using the dial-number collected
thus far; Otherwise, no INVITE is sent until the “(Re-)Dial” button
is pressed or after about 5 seconds have elapsed if the user forgets to
press the “(Re-)Dial” button.
The “Yes” option should be used ONLY if there is a SIP proxy
configured and the proxy server supports 484 Incomplete Address
response. Otherwise, the call will most likely be rejected by the
proxy (with a 404 Not Found error).
Please note that this feature is NOT designed to work with and
should NOT be enabled for direct IP-to-IP calling.
This value contains the dial plan prefix string (typically an ASCII
numeric string). If it is not blank, then this string will be used as a
prefix to the target URI string in the “To” header field of an INVITE
message.
Use # as
Send Key
Local SIP port
Local RTP port
Use Random
Port
This parameter allows the user to configure the “#” key to be used as
the “Send”(or “Dial”) key. Once set to “Yes”, pressing this key will
immediately trigger the sending of dialed string collected so far. In
this case, this key is essentially equivalent to the “(Re)Dial” key. If
set to “No”, this # key will then be included as part of the dial string
to be sent out.
This parameter defines the local SIP port the IP phone will listen and
transmit on. The default value is 5060.
This parameter defines the local RTP-RTCP port pair the IP phone
will listen and transmit on. It is the base RTP port for channel 0.
When configured, channel 0 will use this port value for RTP and the
port_value+1 for its RTCP; channel 1 will use port_value+2 for RTP
and port_value+3 for its RTCP. The default value is 5004.
This parameter, when set to Yes, will force random generation of
both the local SIP and RTP ports. This is usually necessary when
multiple IP phones are behind the same NAT.
- 20 -
HandyTone 286 User Manual Grandstream Networks, Inc.
f
NAT Traversal
keep-alive
interval
This parameter defines whether the phone NAT traversal mechanism
will be activated or not. If activated (by choosing “Yes”) and a
STUN server is also specified, then the phone will behave according
to the STUN client specification. Under this mode, the embedded
STUN client inside the phone will attempt to detect if and what type
of firewall/NAT it is behind through communication with the
specified STUN server. If the detected NAT is a Full Cone,
Restricted Cone, or a Port-Restricted Cone, the phone will attempt to
use its mapped public IP address and port in all the SIP and SDP
messages it sends out.
If this field is set to “Yes” with no specified STUN server, then the
phone will periodically (every 10 seconds or so) send a blank UDP
packet (with no payload data) to the SIP server to keep the “hole” on
the NAT open.
The HT286 sends a UDP package to the SIP server periodically in
order to keep the port open on the router. This parameter defines the
interval time that HT286 send the UDP package. The default setting
is 20 second.
Use NAT IP
TFTP Server
SUBSCRIBE
or MWI
Offhook
Auto-Dial
NAT IP address used in SIP/SDP message. Default is blank.
This is the IP address of the configured tftp server. If it is non-zero
or not blank, the IP phone will attempt to retrieve new configuration
file or new code image (update) from the specified tftp server at boot
time. It will make up to 3 attempts before timeout and then it will
start the boot process using the existing code image in the Flash
memory. If a tftp server is configured and a new code image is
retrieved, the new downloaded image will be verified and then saved
into the Flash memory.
Default is NO. When set to Yes a SUBSCRIBE for Message Waiting
Indication will be sent periodically
This parameter allows the user to configure a User ID or extension
number to be automatically dialed upon offhook. Please note that
only the user part of a SIP address needs to be entered here. The
phone will automatically append the “@” and the host portion of the
corresponding SIP address.
Enable Call
Feature
Default is No. If set to Yes, Call Forwarding & Do-Not-Disturb are
supported locally.

HandyTone 286 User Manual Grandstream Networks, Inc.
Disable Call
Waiting
Send DTMF
Send Flash
Event
NTP server
Time Zone
Daylight
Savings Time
Default is Not.
This parameter controls the way DTMF events are transmitted.
There are 3 ways: in audio which means DTMF is combined in
audio signal (not very reliable with low-bit-rate codec), via RTP
(RFC2833), or via SIP INFO.
This parameter allows the user to control whether to send an SIP
NOTIFY message indicating the Flash event, or just to switch to the
voice channel when the user presses the Flash key.
This parameter defines the URI or IP address of the NTP server
which the IP phone will use to display the current date/time.

6.3 Configuration through a Central Server
Grandstream IP phones can be automatically configured via a central provisioning
system called Grandstream Automated Provisioning System (GAPS).
With GAPS, a service provider or an enterprise with large deployment of IP phones can
easily manage the configuration and service provisioning of individual devices remotely
and automatically via a central server. GAPS uses enhanced (NAT friendly) tftp and

other communication protocols to communicate with each individual IP phone even if
the phone is behind a NAT.
GAPS must be used to support automated configuration of an IP phone. To enable this
feature on the phone, the user just needs to enter the IP address of GAPS server in the
tftp server field of the configuration screen. Then power cycle the phone.
For details on how GAPS works, please refer to the documentation of GAPS product.

7 Software Upgrade with TFTP
To upgrade software, HandyTone ATAs can be configured with a TFTP server where
the new code image is located. The TFTP upgrade can work in either static IP or DHCP
mode using private or public IP address. It is recommended that the TFTP server must
have either public IP address or be on the same LAN with the HandyTone ATA.
There are 2 ways to set up the TFTP server to upgrade the firmware, namely through
voice menu prompt or via the HandyTone ATA’s Web configuration interface. To
configure the TFTP server via voice prompt, follow section 4.1 with option 06, once set
up the tftp ip address, power cycle the ATA, the firmware will be fetched once the ATA
boot up.
To configure the TFTP server via the Web configuration interface, open up your
browser to point at the IP address of the HandyTone ATA. Input the admin password to
enter the configuration screen. From there, enter the TFTP server address in the
designated field towards the bottom of the configuration screen.
Once the TFTP server is configured, power cycle the HandyTone ATA.
TFTP checking is only performed during the initial power up. If the configured tftp
server is found and a new code image is available, the HandyTone ATA will attempt to
retrieve the new image files by downloading them into the HandyTone ATA’s SRAM.
During this stage, the HandyTone ATA’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 fails for any reason (e.g., TFTP
server is not responding, there are no code image files available for upgrade, or
checksum test fails, etc), the HandyTone ATA will stop the TFTP process and simply
boot using the existing code image in the flash.
TFTP may take as long as 1—2 minutes over Internet, or just 20+ seconds if it is
performed on a LAN. It is generally recommended to conduct TFTP upgrade in a
controlled LAN environment if possible. For users who do not have local TFTP server,
Grandstream provides a NAT-friendly TFTP server on the public Internet for users to
download the latest firmware upgrade automatically. Please check the Service or
Support section of Grandstream’s Web site to obtain this TFTP server IP address.

8 Restore Factory Default Setting
Warning: Restore the Factory Default Setting will delete all configuration
information of the device.
Step one: Find the Mac Address of the device. The Mac address of the device is located
on the bottom of the device. It is a 12 digit number.
Step two: Encode the Mac address. The encode rule is:
“2” is the first letter on the button “2” so its encoding is “2”.
“A” is the second letter on button “2” so its encoding is “22”.
“B” is the third letter on button “2” and its encoding is “222”.
“C” is the fourth letter on button “2” and its encoding is “2222”.
For example, the Mac address is 000b8200e395,
User should encode it as “0002228200333395”.
Step three: Access the voice menu, then dial “99” and get the voice prompt “RESET”
Step four: Dial in the encode of the Mac address. Once the correct encode Mac address
dial in, the device will reboot automatically and restore the factory default setting.
