What is a channel group?

A channel group is a container of individual channels and is normally named to reflect the type of channel it contains, such as ISDN30, ISDN2, Analogue, etc.

The Discovered Channels folder

A special channel group, Discovered Channels, is automatically created in TIM Plus to harvest hitherto-unknown channel information from the call data received from your telephone system. Over time, when all possible channels have been collected by the Discovered Channels folder, you can create your own channel groups based on the structure of your organisation, and move channels into these new groups.

Adding a channel group

To add a new channel group to the Directory, select the Channel groups tab from the Groups panel and click on the Add button.

A new window will appear, allowing you to enter the group's name and its associated trunk access code (TAC), if applicable.

Click on the Add button to add the new group to the Directory.

If you use synchronisation, such as Cisco AXL, you need not manually configure channel groups, since TIM Plus automatically imports channels from your telephone system, placing them in their respective groups.

Configuring a channel group

To configure the properties of a channel group, highlight the group you want to configure and click on the Properties button at the top-right corner of the panel:

A new window will open, where you can configure the properties of your channel group. Each tab in the Group properties window is described below:


In the General tab you can edit the name of the channel group and its associated access code, if applicable.

Channels in this group emulate network termination

This option only applies if you have enabled integrated call recording on your system. Its purpose is to indicate that the far end of the channel's physical connection is emulating PSTN network termination (NT), such as in a private circuit scenario.


The Telephony tab gives you the option to exclude the currently-selected group from being logged by TIM Plus. If call recording integration is enabled, you can also exclude calls from being recorded.

Do not logCalls for this channel group will not be logged by TIM Plus. In addition, if integrated call recording is in use, no audio recordings will be available
Do not record callsCalls for this channel group will not be recorded, if integrated call recording is in use
Exclude channels from call statisticsCollection of statistics will not be performed for this channel group


The Tariff tab gives you the ability to select a default tariff table to use, when costing calls for this channel group.

By default, TIM Plus is supplied with a standard BT tariff which will automatically pick up national, international and mobile dial codes. Bespoke tariffs can also be provided on request.

Renaming a channel group

To rename a channel group, locate it in the Directory and click on the Properties tab.

A new window will open, where you can specify a new name for the group. Click Save to apply the changes.

Deleting a channel group

When you delete a channel group, you are deleting all the information contained within that group, including all channels and the calls associated with those channels!

To remove a channel group from the Directory, select the group you want to remove and click on the  Properties button. In the Channel properties window that will open, click on the Delete button to remove the channel from the Directory; a confirmation will be required, to prevent users being deleted accidentally.
