BT Quantum: ring groups, hunt groups and incoming ringing

The BT Quantum phone system is no longer supported by BT Business. Support ended on 30 September 2025, and we won't update this page if anything changes with the product. 

If you're looking for a replacement system, check out all our cloud-based phone systems. 

We've brought our BT Quantum ring groups help together in one post. It covers how ring groups work, creating a linear hunt group, and adding or removing extensions from ringing on incoming calls. 

 

Ring groups

There are 20 ring groups and they can all be used in any order (groups 11 to 20 are slightly different as you’ll discover below). 

Groups let you organise your extensions. For example, the extensions you want to ring when someone calls can all go in one group, and the system can be programmed to ring that group. Each group can hold from a single extension up to 15 extensions. 

By default, group 1 is programmed with extensions 201 to 207, and all the other groups are programmed with extension 201 only. Every group must have at least one extension. The default ringing setting is for all lines to ring group 1, so extensions 201 through 207 will all ring if free. 

Each group has a number on the system, just as each extension does: group 1 is 180, group 2 is 181, and so on until group 20, which is 199. On a defaulted system, if an extension dials 180, extensions 201 through 207 will ring if free. If an extension dials 194, the extensions in group 13 will ring if free (in default, that would be extension 201 only). 

Direct Dialling In (DDI) numbers – numbers that ring straight through to a specific extension or group without going through the switchboard - can be programmed to ring a group. Set the group up with the extensions you want to ring when someone calls the DDI number. 

 

Group mailboxes

If a group has a mailbox enabled, extensions in the group can divert calls for the group to the mailbox using the Group divert feature (divert all calls, divert on busy, and divert on no reply). The mailbox number for the group is the same as the group number (180 to 199). 

 

Groups 11 to 20

Groups 11 to 20 have an extra feature: they can be used to allow single-digit dial-through of the auto attendant. 

To set up a ring group, see page 61 of the BT Quantum Administrator’s Guide. 

 

Creating a linear hunt group

With linear hunting, calls always go to the first extension in the group if it’s available. If it’s busy, the call goes to the next extension in the group. Use it when you want one extension to take most of the calls, with backup call handling from the others. 

From the web interface: 

  1.      Open and log in to the web interface. 
  2.      Select Extensions / Extension Groups to display the extension groups page. 
  3.      Select the group type (Linear) for the group you want to programme. 
  4.      Select Submit. 

From the programming extension: 

  1.      From the programming extension (201 by default), press the Program key. 
  2.      Select System Program and enter the system programming password (1111 by default). 
  3.      Select Group Program. The 20 groups are listed. 
  4.      Select the group you want to programme. Two options are shown: Ring Group and Hunt Group. 
  5.      Select Hunt Group, then select the type of group (Linear). 
  6.      Press the Hands-free key to finish. 

 

Adding or removing extensions from ringing on incoming calls

From the web interface: 

  1.      Open and log in to the web interface. 
  2.      Select Extensions / Extension Groups to display the extension groups page. The 20 groups are listed across two pages. Select 1-10 or 11-20. 
  3.      Select Members to open the members page. It contains a drop-down for each extension in the system, ordered by position in the group. 
  4.      To add an extension, select it from the next spare drop-down box. To remove one, change its drop-down to none. 
  5.      Select Submit. 

From the programming extension: 

  1.      From the programming extension (201 by default), press the Program key. 
  2.      Select System Program and enter the system programming password (1111 by default). 
  3.      Select Group Program. The 20 groups are listed – select the one you want. 
  4.      Two options are shown, Ring Group and Hunt Group – a solid square shows the type currently set. 
  5.      Extensions in the group show a solid square. To add an extension, press the button next to its number or name so the square becomes solid. To remove one, press its button so the square becomes clear. 
  6.      Press the Hands-free key to finish.

Hello,
This guide provides a clear and detailed explanation of BT Quantum ring groups, including how they work, how to configure hunt groups, and how to manage extensions. The step-by-step instructions for both the web interface and programming extension make it easier for administrators to set up call routing. It is especially helpful for businesses that need flexible call handling, mailbox options, and efficient distribution of incoming calls.
