The number of channels assigned to a trunk, forward or voicemail dictate how many concurrent inbound calls can be accepted by that endpoint. If you have a trunk with five channels then you will be able to receive five calls on your device. Channels are allocated to your account, additional channels can be purchased through the online shop, these channels can then be split between your various trunks, forwards and voicemails.

As shown in the screenshot to the right, channels can adjusted by dragging the sliders up and down. This will update the channels assigned to that endpoint and the changes and can be confirmed using the save button.
