GHP61X/W Wall Mount

To mount the GHP61X/W on the wall:

• Mark two dots horizontally with a 100 mm distance between them where you intend to mount the phone.
• Using a drill, make a hole at each marked dot. Insert a plastic expansion bolt and screw (not provided) into each hole. Ensure enough space is left on the screws to mount the phone.
• Mount the GHP61X/W onto the screws using its "Wall Mount Slots".

GHP62X/W Wall Mount

To mount the GHP62X/W on the wall:

1. On the wall where the GHP62X/W will be mounted, mark two dots vertically with a 100 mm distance between them.
2. Using a drill, make a hole at each marked dot. Insert a plastic expansion bolt and screw (not provided) into each hole. Ensure enough space is left on the screws to mount the phone.
3. Attach the wall mount spacers to the designated slots on the back of the phones.
4. Mount the GHP62X/W onto the screws using its "Wall Mount Slots".

Connecting the GHP6XX/W

To set up the phone, follow these steps:

1. Connect the phone cord to the handset (RJ-11 port) and the base.
2. 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 an Ethernet cable. This step can be skipped if using GHP6xxW with Wi-Fi.
3. Powering the phone:
   • For GHP6XX/W: Connect the 12V DC output plug into the power jack, and plug the power adapter into the electrical outlet.
   • For GHP6XX & GHP6XX: A PoE switch must be used in step 2.

Note: For easy deployment, the GHP6xxW models are pre-configured to connect to the default SSID "wp_master" with the password "wp!987@dmin". Users can adapt these settings via the web UI.

Phone Configuration Via Web Browser

1. Ensure your phone is powered up and connected to the internet.
2. Locate the MAC address on the MAC tag of the unit (underside of the device) or on the package.
3. From a computer connected to the same network as the GHP6XX, type the following address into your browser, using the GHP6XX's MAC address: https://<mac>.local. Example: https://c074adffffff.local.
4. Enter the administrator's username and password to access the configuration menu. (The factory default username is "admin"; the default random password is on the sticker at the back of the unit).

Note: The user can dial **47#, and the IP address will be read by the IVR.

Telephony Features

Making Phone Calls

Handset and Speaker Mode

The GHP6XX allows switching between the handset and the speaker during calls. Press the ▶️ to use the speaker. To switch back to the handset, simply unhook it, and the audio will transfer to the handset's speaker.

Dial the desired number and press '#' to send the call, or wait a moment for the number to be sent automatically.

SIP Accounts and Lines

The GHP6XX supports 2 SIP accounts and 2 lines. Each account can connect to independent SIP servers and users. One account is typically configured by the administrator for initiating and receiving calls, while the other is configured for receiving calls. The default account can only be switched by the administrator.

Completing Calls

There are several ways to complete a call:

• On-hook dialing: Enter the number while the phone is on-hook and then send it.
  • When the phone is idle, enter the number to be dialed.
  • Take the handset off-hook, press the ▶️, or press the headset button if a headset is plugged in.
  • The call will be dialed out.
• Off-hook and dial: Take the phone off-hook, enter the number, and send it.
  • Take the handset off-hook or press the ▶️. You should hear a dial tone.
  • Enter the number.
  • Press the '#' key to dial out.
• Redial: Redial the last dialed number.
  • Take the handset off-hook, press the ▶️, press the headset button (if plugged in), press an available LINE key to activate the speaker, or when the phone is in an idle state.
  • To redial, you can either press the redial key (which composes the last entered number) or press the '#' key (which triggers a DTMF call to the last composed number).
• Multi-Purpose Keys: These keys can be configured to quickly dial extensions. When a Multi-Purpose Key (MPK) is pressed, the number is dialed and the call is sent out.
