Voice channels

A voice channel is how calls reach Live Hub. You need at least one before a bot can answer a call, and you can combine several channels in one account.

Whichever you choose, the channel on its own does nothing until a routing rule connects it to a bot connection.

Choose a channel

Each channel type suits a different deployment:

Channel	Use it when
Phone numbers	you want AudioCodes to provide the phone number. This is the quickest way to get a working phone number. See also supported countries.
SIP connections	you already have a SIP trunk, PBX, or contact center to connect. Pre-integrated vendors are listed in the interop guides.
WhatsApp numbers	you want calls over WhatsApp
Microsoft Teams	you want Live Hub to carry voice for a Teams tenant
Click-to-call (WebRTC)	you want calls started from a button in your own web page or mobile application, over WebRTC

In the portal, the first four appear under the Voice channels menu. Click-to-call does not appear there: you create it as a SIP connection whose provider type is Client Applications.
