4.4Making 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 “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).

19
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 many 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.
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.

20
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
by pressing the line button, and automatically put an ACTIVE call on Hold.
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.
