4.4 Making and Answering Phone Calls
4.4.1 Handset, Speakerphone and Headset Mode
The regular Handset mode can be switched with either the Speaker mode (Hand free) or
the Headset mode, however, whenever the Headset is plugged in, Speaker mode will be
switched to the Headset mode automatically.
To Switch between Handset and Speaker/Headset, simply press the Hook Flash in the
Handset cradle or the Speaker button.
4.4.2 Multiple SIP Accounts and Lines
GXP-2000 can support up to 4 independent SIP accounts. Each account is capable of
independent SIP Server, user and NAT settings among others. GXP-2000 supports up to
11 concurrent audio channels arbitrarily assigned to these SIP accounts -- they can be
used in any combination as long as the server allows it. Speed dial numbers configured
must be associated to a specific SIP account.
Each of the 4 LINE buttons (LINE1-LINE4) is “virtually” mapped to each SIP
account. In off hook state, when user chooses an idle line, the name of the account (as
configured in the web interface) will be displayed in the LCD while a dial tone is being
played out. For example, if the 4 SIP accounts are named FWD, SIPPHONE,
BROADVOICE, and PBX respectively and they are all active and registered. When
LINE1 is pressed, user will hear dial tone and see “FWD”. When LINE2 is pressed, user
will hear dial tone and see “SIPPHONE”. When LINE3 is pressed, user will hear dial
tone and see “BROADVOICE”. When LINE4 is pressed, user will hear dial tone and see
“PBX”.
For outgoing calls, GXP-2000 will pick up the LINE pressed, which will be lit up in solid
red color. User can switch the dialing account before dialing any digits by pressing the
same LINE button one or more times. If user continues to press one LINE, the selected
account will circulate among the registered accounts. For example, when LINE1 is
pressed, LCD displays “FWD”. If LINE1 is pressed again, LCD displays “SIPPHONE”
and the subsequent call will be made through SIP account 2.
For incoming calls, if an account is configured and registered, all incoming calls for that
account will attempt to use its corresponding LINE if it is not in use. When the

16
“virtually” mapped line is in use, GXP-2000 will flash the next available LINE (from
Left to Right, then Top to Bottom) in red color.
LINE 5 to 11 cannot be picked like LINE 1 to 4. This happens automatically. When an
incoming call arrives while all of the 4 LINE (1-4) channels are in use, LINE5 will be
selected. When all 4 LINE (1-4) channels are in use, and user places an active call on
hold, user can on-hook and off-hook to activate the next available channel (LINE5 or
whatever the next one). When any one of the 7 functions keys is associated with a call,
they function as LINE keys; otherwise they function as speed dial keys. (So when LINE
5 is in use, you cannot use speed dial 1, but speed dial 2-7 still work).
A LINE is defined as “ACTIVE” when it is making or receiving a call, and its
corresponding LINE LED is lit up in solid RED.
4.4.3 Making Calls
There are three ways to make phone calls:
1. Make Handset/SPEAKER/Headset off hook, or press the available LINE key to
select a SIP account, the corresponding LINE LED will light up in solid red. Enter
the phone numbers and press the SEND key.
2. Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the
corresponding LINE LED will light up in solid red. Press the SEND button to
redial the last number called.
3. Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the
corresponding LINE LED will light up in solid red. Press the Speed Dial key to
call the preset calling party number.
4. Press the DOWN button, then select the number in the Phone Book menu you
want to call by pressing the Menu button, and then press the Menu button again to
call this number.
5. Press the UP button, then select the number in the Missed Calls you want to call
by pressing the Menu button, and then press the Menu button again to call this
number.
Note:
•Once pressed, the dialed number is displayed on the LCD as the corresponding
DTMF tone is played out.
•If the “SEND” button is not pressed after the phone number, the phone will wait
for 4 seconds before initiating the call.

17
4.4.4 Making Calls using IP Address
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 phones have public IP addresses, or
•Both phones are on a same LAN using private or public IP addresses, or
•Both phones can be connected through a router using public or private IP
addresses.
To make a direct IP calling, disable “Use Random Port” option at advanced web
configuration page, and then press “Menu” button, and then select “Direct IP Call”
submenu to enter the direct IP call interface, and then enter the 12-digit target IP address,
and then press Menu button twice to make the call.
From 1.1.0.13 firmware build, GXP2000 begins to offer Quick IP-call feature: first make
Handset/SPEAKER/Headset off hook, and then press # key and enter the last 3-digits of
the target IP address, and then press the SEND key or # key. To use this feature, you need
to enable Quick IP-call mode in the advanced web configuration page.
4.4.5 Receiving Calls
There are two states when GXP-2000 receives a call:
1. When receiving an initial call. Besides ringing with selected Ring Tone, the
corresponding account LINE will flash in red, taking Handset/SPEAKER/Headset
off hook will enable user to hear the calling party in Handset/SPEAKER/Headset.
2. When receiving second or more incoming calls, besides playing stutter Call
Waiting tone, GXP-2000 will pick up the corresponding account LINE or the next
available LINE as described in section 4.4.2.
4.4.6 Call Hold
While in conversation, pressing the “HOLD” button will put the other party on hold. User
can resume the conversation by pressing the corresponding LINE. User will also
automatically put the current line on “HOLD” by pressing another available LINE for
making or receiving other phone calls.
4.4.7 Call Waiting and Switch between Calls
GXP-2000 can support up to 11 Lines, user can switch to another line for making or
answering calls and automatically put an ACTIVE call on Hold.

18
When receiving second or more incoming calls, besides playing a stutter Call Waiting
tone, GXP-2000 will pick up the corresponding account or the next available LINE as
described in section 4.4.2.
4.4.8 Call Transfer
GXP-2000 supports both BLIND and ATTENDED Transfer:
1. Blind Transfer: When a LINE is “ACTIVE”, user will get a dial tone by pressing
the “TRNF” button, and then dial the number and press the “SEND” button. This
will transfer the other party in the corresponding LINE to the dialed number.
2. Attended Transfer: When in conversation with an “ACTIVE” LINE as defined in
section 4.3.2, user shall press “TRNF” button, then press the intended LINE that
is on “HOLD”.
If there is no LINE on HOLD, user will need to make a call and thus
automatically puts the current ACTIVE LINE on HOLD.
NOTE:
•Transferring calls across SIP domains needs to be supported by SIP services.
4.4.9 3-Way Conferencing
GXP-2000 supports 3-way conferencing. With one LINE ACTIVE and another LINE on
HOLD, press the CONF button then the LINE that is on HOLD will join the three parties
together in a conference.
If after pressing the “CONF” button, a user decides not to conference anyone; user can
cancel it and resume the conversation by pressing CONF or the original LINE button.
If the conference holder wishes to end a conference, simply press HOLD, which breaks
the conference and places both parties on hold. User can then talk to each individual
party by selecting the corresponding LINE.
4.4.10 Checking Message and Message Waiting Indication
When GXP-2000 is on-hook, pressing the MSG button will trigger the phone to call the
VM Server (VMS) configured for the primary account. If a line/account is selected first,
it dials the VMS configured for that account.

19
The MWI (Message Waiting Indicator) LED will flash in red color in three quarters of a
second when voicemail server sends message waiting information to GXP-2000.
4.4.11 Mute and Delete
When in conversation with an ACTIVE LINE, pressing “MUTE/DEL” will mute the
conversation, that is, you can hear the other party but the other party cannot hear you.
Pressing the button again will resume the conversation.
When dialing a number, press “MUTE/DEL” will delete the last entered digit.
4.4.12 Speed Dial
There are 7 speed dial buttons; each can be configured with a different account to dial. A
vertical rectangle pad on the keypad is provided to label Speed Dial numbers.
When an incoming call arrives while all of the 4 LINE (1-4) channels are in use, the
speed dial buttons will be selected as LINE indicators. When any one of the 7 functions
keys is associated with a call, they function as LINE keys; otherwise they function as
speed dial keys. (So when LINE 5 is in use, you cannot use speed dial 1, but speed dial
2-7 still work).
4.4.13 Asterisk Busy Line Field
These 7 speed dial buttons also can be configured for Asterisk Busy Line Field function
with a different account. When Asterisk BLF is configured on one of the speed dial
buttons, Speed Dial function on it will still work when it is at idle status for Asterisk BLF
function.
