4.3 Making and Answering Phone Calls
4.3.1 Handset, Speakerphone and Headset Mode
Handset can be switched with either Speaker or Headset, however, whenever Headset is
plugged in, Speaker will be switched to Headset.
To Switch between Handset and Speaker/Headset, simply press the Hook Flash in the
Handset cradle.
4.3.2 Lines and Calls
By default, GXP-2000 support 4 lines with LED and they can be extended up to 11
lines. A LINE is defined “ACTIVE” when it is making or receiving a call, and its
corresponding LINE LED in solid RED.
GXP-2000 will pick up the next available LINE when active one or more LINE are on
hold, for incoming calls, GXP-2000 will flash the available (in ascending order) LINE
in red color, for outgoing calls, GXP-2000 will pick up the next available (in ascending
order) LINE in solid red color, or use the LINE pressed.
4.3.3 Making Calls
There are three ways to make phone calls:
1. Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the
corresponding LINE LED will light up solid red then enter the phone numbers
and then SEND key.
2. Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the
corresponding LINE LED will light up solid red then press the SEND/REDIAL
button directly to redial the last number called and then SEND key.
3. Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the
corresponding LINE LED will light up solid red then press the Speed Dial key to
call the preset calling party number and then SEND key.
Note:

GXP-2000 User Manual Grandstream Networks, Inc.

•Once pressed, the dialed number will be displayed on the LCD as the
corresponding DTMF tone played out.
•If the “SEND” button is not pressed, the phone will wait for about 5 seconds
before initiating the call.
4.3.4 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, first pick up the phone or turn on the speakerphone, then
press “Menu” button followed by the 12-digit target IP address. If there is a user part,
press “Menu” button and then the encoded user part, 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:
Input Encoding
00 0
01 1
02 2
03 3
04 4
05 5
06 6
07 7
08 8
09 9
*0 . (dot character)
*1 _ (underscore character)
*2 - (hyphen character)
*3 @
*4 : (column character)

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 2nd letter on button “1” and its encoding is “12”. “c” is
the 3rd 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 apply to all other alphabetic
encoding.
Examples:
If the target IP address is 192.168.0.160, the dialing convention is
Menu_key 192168000160
followed by pressing the “(Re)Dial” button or the “#” key is it is configured as a send
key. In this case, the default destination port 5060 is used if no port is specified.

GXP-2000 User Manual Grandstream Networks, Inc.
- 18 -
If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:
Menu_key 192168001020*45062
followed by pressing the “SEND(Re)Dial” button or the “#” key is it is configured as a
send key.
If the target address is [email protected]:5062, then the dialing convention would
be:
Menu_key 51634262*3192168001100*45062
followed by pressing the “SEND/(Re)Dial” button or the “#” key is it is configured as a
send key.
4.3.5 Answering Incoming Calls
There are two states when GXP-2000 receives a call:
1. When receiving an initial call. Besides ringing with selected Ring Tone, LINE1
will flash in red, making Handset/SPEAKER/Headset off hook will enable user to
hear the calling party in Handset/SPEAKER/Headset mode.
2. When receiving second or more incoming calls, besides playing stutter Call
Waiting tone, GXP-2000 will pick up the next available LINE as described in
section 4.3.2.
4.3.6 Call Hold
While in conversation, pressing the “HOLD” button will put the calling party on hold.
User can resume the conversation by pressing the corresponding LINE. User will also
put the current line on “HOLD” by simply press another available LINE for making or
receiving phone calls.
4.3.7 Call Waiting and Switch between Calls
GXP-2000 can support up to 11 Lines, thus, user can put an active call on Hold and
automatically switch to the other line for making or answering calls.
When receiving second or more incoming calls, besides playing stutter Call Waiting
tone, GXP-2000 will pick up the next available LINE as described in section 4.3.2.
4.3.8 Call Transfer
GXP-2000 support both BLIND and ATTENDED Transfer:

GXP-2000 User Manual Grandstream Networks, Inc.
- 19 -
1. Blind Transfer: When a LINE is “ACTIVE”, user will get a dial tone by pressing
the “TRNF” button, then dial the number and press the “SEND” button, this will
transfer the other party in the corresponding LINE to the dialed number blindly.
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 next 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.
4.3.9 Checking Message and Message Waiting Indication
Pressing MSG button will trigger GXP-2000 to call the pre-configured voicemail server
number.
The MWI (Message Waiting Indicator) LED will flash in red in three quarter of a
second when voicemail server sent message waiting info to GXP-2000.
4.3.10 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 can not hear you,
press the button again will resume the conversation.
When dialing a number, press “MUTE/DEL” will delete the last entered digit.
4.3.11 Speed Dial

and a vertical rectangle pad can be used for labeling Speed Dial Number.
