GHP6XX/W Phone Setup
The GHP6XX/W can be installed on the desk or mounted on the wall. To mount the phone on the wall, please follow the instructions below.
GHP61X/W
GHP61X Wall Mount
Mark two dots horizontally with a 100 mm distance in between where to wall mount the GHP610/W & GHP611/W.
Using a drill, make a hole in each marked dot. Put a plastic expansion bolt and screw (not provided) on each hole. Leave enough space to mount the GHP610/W & GHP611/W.
Mount the GHP610/W & GHP611/W on the screws using the Wall Mount Slots.
GHP62X/W
GHP62X Wall Mount
On the wall where the GHP62X/W will be mounted, mark two dots with 100 mm distance in-between vertically.
Using a drill, make a hole on each marked dot. Put a plastic expansion bolt and screw (not provided) into each hole. Leave enough space on the screws to mount the GHP62X.
Attach the wall mount spacers to the slot for the wall mount spacer on the back of the phones.
Mount the GHP62X on the screws using its “Wall Mount Slots”.
Connecting the GHP6XX/W
To set up the phone, follow the steps below:
Connect the phone cord with the handset (RJ-11 port) and the base.
Connect the LAN port of the phone to the RJ-45 socket of a hub/switch on a router ( LAN side of the router) using the Ethernet cable. This step can be skipped if using GHP6xxW with Wi-Fi.
Powering the phone:
For GHP610W & GHP611W & GHP620W & GHP621W HW below version 5.0: Connect the 12V DC output plug into the power jack of the phone; plug the power adapter into the electrical outlet.
For GHP6xx & GHP6xx & GHP6xxW & GHP6xxW HW above version 5.0: A PoE switch must be used in step 2.
Note
For easy deployment, the GHP6xxW is out-of-the-box pre-configured to connect to default SSID named wp_master with a password (WPA/WPA2 PSK) equal to wp!987@dmin, users can adapt these settings from the web UI as well to make it easier for deployment on a customer’s site.
Phone Configuration Via Web Browser
Ensure your phone is powered up and connected to the internet.
Locate the MAC address on the MAC tag of the unit, which is on the underside of the device or the package.
From a computer connected to the same network as the GHP6XX, type in the following address using the GHP6XX’s MAC address on your browser: https://<mac>.local Example: https://c074adffffff.local Note: The user can dial **47#, and the IVR will read the IP address.
Enter the admin’s username and password to access the configuration menu. (The factory default username is “admin” while the default random password can be found on the sticker at the back of the unit.)
Note:
To enable users to listen to the IP address via IVR by dialing **47#, the “Key As Send” parameter under Account→Call Settings must be set to the Pound (#) key. If this setting is not configured, users will need to dial **47 and wait for the timeout to get the IP address.

Press the # key, this will trigger a DTMF call to the last composed number
Multi-Purpose Keys: Multi-purpose keys can be configured to quickly dial a certain extension. When the MPK has been pressed, the number will be quickly dialed and the call sent out.
Direct IP Calling
Direct IP Call allows two phones to contact each other without a SIP proxy. VoIP calls can be made between two phones if:
Both phones have public IP addresses; or
Both phones are on the same LAN/VPN using private or public IP addresses; or
Both phones can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).
To make a direct IP call, please follow the steps below:
Take the handset off-hook, press the Speaker button, or press the Headset button on the headset plugged in.
Input the target IP address (Please see the example below).
Press the Send key or wait for the timeout.
Example:
If the target IP address is 192.168.1.60 and the port is 5062 (i.e., 192.168.1.60:5062), input the following: 192*168*1*60#5062. The * key represents the dot (.), and the # key represents the colon (:).
When only dialing the IP address (example: 192*168*1*60), the call will automatically go through the default port 5060.
Notes:
Users need to enable Direct IP Call under Phone Settings→Call Settings→Outgoing, before attempting to make calls using IP addresses.
When using direct IP calls, the “Use Random Port” option in Phone Settings→Basic Settings should be set to “No”.
Answering Phone Calls
Receiving Calls
The phone rings with the selected ringtone. Unhook the handset or press the speaker button to answer the call.
Note
Please note that due to the nature of the environment that this phone is deployed on, it’s not possible to reject a call.
During a Phone Call
Call Waiting/Hold Call
User can use the hold button to put the call on hold.

During an active call, press the MUTE button to mute/unmute the microphone. The LED will light up in red to indicate that your microphone is muted.
Call Transfer
Attended Transfer
Alice is talking with Bob.
Alice presses Flash to initiate a new call to Carl, and Bob is held automatically.
Carl answers the call, and Alice talks with Carl about Bob. Then Alice hangs up the call, and Bob will be transferred to Carl.
If Carl rejects or does not answer the call, Alice could press Flash to retrieve the call with Bob.
If the call is still ringing, Alice could cancel the new call by pressing “FLASH” and retrieve the call with Bob automatically.
Attended Transfer Before Answer
Alice is talking with Bob.
Alice presses Flash to initiate a new call to Carl, and Bob is held automatically.
Carl answers the call, and Alice talks with Carl. Then Alice hangs up the call, and Bob will be transferred to Carl.
If Carl rejects or does not answer the call, Alice could press Flash to retrieve the call with Bob.
If the call is still ringing, Alice could cancel the new call by pressing “FLASH” and retrieve the call with Bob automatically. If Alice hangs up the call while the call to Carl is still ringing, the call will be transferred to Carl before Carl answers. This explains why it is an attended transfer “before answer”.
Note
For these Transfer processes to work, the “Enable Recovery on Blind Transfer” feature needs to be disabled in the web UI under Account => Call Settings => Transfer.
Three-way Conference
If there is one line in use, press the Flash button to start a new call, and long-press Flash to set up a conference after the new call is answered:
Alice is talking with Bob
Alice starts a new call with Carl by pressing Flash, and Bob is held
There are three situations:
If Carl does not answer the call, Alice could press Flash to retrieve Bob.
Alice could also press Flash to cancel the call and go back to the call with Bob.
Once Carl answered the call, Alice could long-press Flash to set up the conference
If Alice wants to end to call with Carl on the conference, she could press Flash.
If Alice wants to end the conference and keep calls, she could long-press Flash, then Bob will be held, and Alice will go back to the call with Carl.
If Bob or Carl hangs up his call, Alice will go back to the call with whoever stayed on the line.
Once Alice hangs up the phone, all calls and the conference are ended.
If there are two lines in use, to set up a conference:
If Alice holds Bob and is talking with Carl
Alice could press Flash to switch lines, and could also long-press Flash to set up a conference.
If Alice holds Bob and Carl’s calls
Alice could press Flash to switch the line, and could also long-press Flash to set up a conference. Bob and Carl will be unheld automatically
