The Grandstream HT812 and HT814 ATA adapters offer the Hunt Group feature.

When the Hunt Group feature is enabled on the ATA, calls to the group will be sent to the group’s leader, or head. The Hunt Group’s head is the phone assigned to Port 1 on the ATA adapter. All assigned ports on the ATA adapter are members of the Hunt Group. Unassigned ports will not work.

If the group head’s line is busy, the call will roll to the phone assigned to Port 2 on the ATA adapter. If the Hunt Group is configured on an HT814 ATA adapter, calls can also roll to Ports 3 and 4 if the previous lines are in use.

Unlike a Ring Group, a Hunt Group will stop searching as soon as it finds an available line. The call will ring through to the first open phone. If the call is not answered, it will be routed based on the call handling instructions that have been selected for the Hunt Group extension.

The devices connected to the ATA adapter’s ports will behave differently depending on whether a Hunt Group is enabled or disabled.

Enabling and Disabling Hunt Group

The system administrator can enable a Hunt Group on while they are setting up the ATA device for the first time.

To enable or disable the Hunt Group later, the system administrator can follow these instructions:

  1. Log in to as an administrator and navigate to the Devices page.
  2. Select the ATA device you’d like to update.
  3. Select or deselect the Enable Hunt Group on this device option.
  4. Save your changes.

Hunt Group is Enabled

When Hunt Group is enabled, every analog device line connected to the ATA adapter is considered part of the group. The outbound caller-ID will be the number assigned to the group’s head whenever any group member makes an outbound call, and the only calls that the connected analog devices will ever receive are calls that are routed through the Hunt Group.

If a Hunt Group member needs to have additional calling capabilities from their own direct extension, they can be assigned an IP phone or they can set up the mobile app. Those devices will not be part of the Hunt Group and will not be able to make or receive calls from the Hunt Group’s extension.

If a Hunt Group member does not have additional devices, incoming calls to their extension will roll to their voicemail.

Hunt Group is Disabled

When Hunt Group is disabled, the group members will be able to make and receive calls normally from the analog device connected to the ATA adapter. Outgoing calls will have the user’s caller-ID instead of the Hunt Group’s caller-ID. Incoming calls will ring through to the analog device in addition to any other devices that are assigned to the user.
