Voice Channels


The Voice Channels module allows you to view the available voice channels and manage their configuration and deployment.

Voice Channels are phone numbers that external parties can call in order to access the contact centre.
This feature allows the administrator to enter and manage DNIS numbers, agent access numbers, and CLIs.

Commonly, these voice channels are used for Dialled Number Identification Service (DNIS) and, in call centres, the DNIS has become synonymous with inbound phone number. Alternatively, a voice channel might function as a Caller Line Identification (CLI) number or as a number used for Agent Login.

Allocation of a voice channel to a call centre is a configuration process that is done outside of the Workspace. That is, a call centre will have a certain number of channels allocated to it, and these can be seen when the Voice Channel display is selected.

1. Edit Voice Channel

This feature allows you to configure a Voice Channel by assigning a DNIS to a Workflow.

  1. Open the Workspace.

  2. Select Voice from the Channels menu.

  3. Click the Edit icon to the right of the record and the Edit Voice Channel dialog opens. 

Voice channels have the following properties:




Channel Name

Select a Workflow from the drop down list. Any inbound calls to this channel will then be sent to this workflow

Workflow Parameter

Enables you to enter a value that will be passed to the Workflow associated with this Voice Channel - the default is blank.

If you do use the field all incoming calls to this number will be tagged with this parameter which can be used to divert the call to the correct Campaign or Agent.

An example of this would be where several numbers point to one Workflow, callers that dialled a particular number are routed based on the value in this field

Use as inbound number with workflow

Click this if you want to use this number as an inbound number associated with a customer facing IVR


Click the radio button to indicate this number as one that will be used for one of the following:

  • Use as inbound number with workflow

  • Use as agent login number

A voice channel designated as an Agent Login number cannot also be linked to a workflow. When saving changes to a voice channel, an error message will alert you if this combination has been selected.

  • Use as agent Direct-in-Dial number

Once selected, the Agent and Campaign will need to be specified so that calls to this number will be allocated accordingly. If this option is checked, the Workflow chosen above will define what happens if the agent is not available when the call comes in.

For more information, see Direct In Dial

The International telephone format is based on the E.164 standard
