With our VoIP Software it is possible to centrally and automatically configure the majority of Grandstream IP Telephones. This process is know as . For this purpose, pascom phone systems include a Default Configuration ( > ). For most deployment scenarios, these standard settings provide a sufficient set of parameters. However, in some cases, the settings may need to be modified.

By new installations, you should first test the provisioning process with a telephone. Should this be successful then you will be able to deploy further telephones.


In order to automatically deploy (AutoProvision) Grandstream Telephones, a functioning DHCP server is required.

Device Onboarding

Connect the phone to your network. Grandstream IP phones come with a built in switch, allowing you to connect the phone directly via the Ethernet port labelled as LAN. Should you not have a PoE option available, connect the phone to a power supply.

The Grandstream IP phone will now boot and acquires an IP address and the corresponding Basic Configurations via DHCP. After this process is completed, the device will automatically appear under > as well as adding the appropriate SIP peer.

As mentioned above, for every device pascom will also automatically add a SIP peer. In addition, the device username and password will also be automatically generated. The username consists of a randomly generated string followed by the last six digits of the device’s MAC address (15 digits in total). As the IP phones are automatically provisioned, you will not be required to enter this data manually and it is not possible to modify the user data. This is designed to considerably increase security against SIP Brute Force attacks.

The Device Name will be automatically added as signified by the vendor (Grandstream) and the MAC Address. On most IP phones, the MAC address is noted on the device housing, allowing phones to be more simply deployed on site in the correct locations.

After a successful provisioning, the IP phone display should show to correct language and time as well as the text

After the successful phone provisioning, the admin user will be reset by the PBX with the following credentials:

Username: admin
Password: 0000

The Telephone Admin User Password can be changed within the Web UI under system settings. Use the search box and search for the parameter sys.peripherals.access.password and enter your desired password. Finally, you will be required to manually apply the Telephony Configurations and restart the endpoint.

Assigning Users

As soon as the IP phone has appeared in the Device List, it can be edited via the button. Under the tab, the phone can be assigned to a user (or location).

After saving your assignments and reapplying the telephony configurations, all affected IP phones will restart.

Function Testing

The simplest method of testing whether a device has been successfully deployed is to call your Voicemail box via *100. On successfully provisioned phones, you should now hear your Voicemail box prompts.

Accessing the Grandstream Web UI

As previously stated, Grandstream IP phones are provisioned using the default configurations which can be found under > .

When modifying the default configuration settings, ensure you make a duplicate copy of the original using the tool.

In addition, you can set an already edited default configurations as the . Doing so ensures that all newly added IP telephones will automatically be provisioned with these default configurations.

Assigning a Default Configuration

A default configuration can be assigned using multiple methods:

  • Via > > Choose your Basic configuration set and press Under the tab, it is possible to add multiple IP telephones.
  • Via > > Select and edit the IP Telephone and under the tab choose the correct Basic configuration option.

Within the section, you can add your desired keys. The following example highlights how to add the first Virtual-Multi-Purpose-Key:



11 is the BLF key code 0 is the first account on the telephone Max is the label which should appear on the telephone screen 103 is the extension to be watched.

For more information, please refer to our Grandstream Key Documentation.

Via the menu tab , assign these default configurations to the telephones which should have this BLF configuration. Save and apply your changes and once the phones have restarted, the changes will have taken affect.
