Configuring Phones Purchased From Us

Any handsets you have ordered from our online store, at will already be attached to your account.

If you have purchased a handset from a 3rd party, we may be able to be enrol these manually. Please submit a request to with the MAC addresses for more information. Note that administrative charges may apply.

Using the Handset

When you first plug in your new handset, if no profile is associated with it through the My Account Portal as below, it will automatically connect to our platform and display a Setup button on the phone.

To configure your handset, press the Setup button and follow the prompts to set your extension number (normally 3 digits, eg. 101) and provide your name. Once complete, your phone will reboot. If, after 60 seconds, the handset hasn't rebooted, please reboot it manually by pressing the arrow centre key, scroll across to Reboot, then press the centre key again.

Using the My Account Portal

To configure a handset to an extension through the My Account Portal, find the MAC address of the handset you're configuring (1), click in the Profile dropdown (2) and select New Profile (3) or, if you've already created a profile, select the profile you wish to use. To locate a handset's MAC address, for example if you're setting up several and would like to be sure you're working on the correct phone, please see Locating a Handset MAC Address

Set the Phone Name, for example 'Bob' and, if it's not already selected, choose the phone's model.

If you'd like the handset to subscribe to any of your Address Books, select the appropriate entry in the Address Book field. To learn more about setting up address books, please see Portal Guide - Address Book

Select the Extension that this phone should connect to from the Extensions field. If this phone should connect to more than one extension, use the +Add Extension button to attach additional extensions. For more information on creating new extensions, please refer to Portal Guide - PBX Extensions and Sip Trunks

Finally, set Hotdesking to enabled or disabled as required and optionally set a hotdesking PIN. For more information on Hotdesking, see Using Hot Desking

Once the profile has been added and associated with the handset, you can then plugin the handset. Once it boots up, it'll download the configuration and be ready for use. If you have previously connected the phone, a reboot or factory reset may be required before it'll download the configuration. To perform a factory reset, press the Centre key of the arrows, navigate to System, then choose Factory Reset and confirm.

Configuring Keys

Grandstream handsets require at least one Line type key to make and receive calls. This is pre-allocated to the top left key of the first page.

To configure the DSS Keys on your phone, locate the extension or phone you'd like to setup, then click Keys

You will be presented with a picture of your handset, along with the keys available for configuration. To add a function to a key, click the key or the corresponding section on the display.

In the resulting popup, you can select which function you'd like the key to perform, along with the target and a name for the key. For example, choosing another person's extension will configure a BLF and Speed dial key, which will show if they're on the phone, and act as a speed dial to them when pressed.

If you have an expansion module, click the + Expansion Module button to show and allow configuration of the additional keys provided. These are configured in the same way, by clicking their line key or corresponding screen section.

Available Key Types

Line Key: This is a special key type that configures one or more buttons to handle calls coming in to your extension.

PBX Extensions: Configures a key that monitors the state of another extension (eg. on the phone, ringing, available) while also allowing for quick transfers and speed dialling.

External Numbers: Sets up a speed dial key for a number found in Hosted PBX > External Numbers

Timeswitch Positions: Use a key to quickly switch between timeswitch favourites (eg. Lunch timeswitch override). For more information see Time Switch Setup

Call Parking: Configure a key to park a caller and additional keys to monitor individual parking lots, enabling parked caller retrieval. For more information see Call Parking Guide

Custom Values: This allows you to setup a custom key on your handset of either BLF (same functionality as PBX Extensions), Speed Dial (same functionality as external numbers), Line (additional line keys) or Call Park (same functionality as call parking) but manually specifying the target number or extension.

While most keys will synchronise automatically, you can force a resync by clicking the Save & Sync to Phone button.

Resetting Your Phone

If a phone has previously been provisioned, but requires a factory reset, you'll need to 'release' the provisioning profile before the phone will re-download its configuration. To do so, locate the handset under Configured PBX Extensions or Configured Yealink Phones and click Keys. 

From the Actions menu, choose Reset Profile

Once complete, you can now factory reset your phone. To perform the factory reset, press the Centre Key of the arrows, navigate to System and select Factory Reset.


If your handset has not downloaded the configuration set in the My Account Portal or does not show the Setup prompt within 5 minutes of powering on, you can try manually triggering the download by selecting Menu > System > Upgrade > Start Provision.

If the prompt still doesn't appear, your router may be overriding the requests. This behaviour has been seen on Telstra Smart Modems in a DOT environment, but may affect other routers. To stop this override, it's necessary to modify a setting in the handset's web interface.

To access the web interface first retrieve the phone's IP by pressing the menu key, then choosing Status > Network Status. Note down the IPv4 Addr, then enter it into a web browser on a computer connected to the same network.

At the Grandstream login prompt, enter the username 'admin'. The password will be listed on a sticker on the bottom of your handset.

Once logged in, navigate to Maintenance, then Upgrade and Provisioning. Set the field 'Allow DHCP Option 43 and Option 66 to Override Server' to No, then click Save and Apply.

To re-check for configuration, select Tools, locate Provision, then click Start. You should now show the download symbol and begin the configuration process.

Handsets From 3rd Parties

If you have purchased a handset from a 3rd party, we may be able to be enrol these manually. Please submit a request to with the MAC addresses for more information. Note that administrative charges may apply.
