A Channel is a communication mechanism. A User's available Channels determine how they can send and receive communications.
The Channels supported are:
- A User uses an App (Channel) to send in-app messages (Media) in a chat.
- A User uses a Phone (Channel) to receive Voice calls (Media) on their phone device.
It is then possible to mix Channels so that you can create:
- An App (Channel) makes a Voice (Media) call to a mobile Phone (Channel).
- A Phone (Channel) makes a Voice (Media) call to a Websocket (Channel).
The following table shows how each Channel supports each Media:
|Channel||In-app Messaging||In-app Voice||PSTN||SIP||Websocket||In-app Video|
You can send a type of Media through a Channel. Some Channels (such as App, can support multiple media types, for example In-app Messaging, In-app Voice and In-app Video).
The relationship between Media and Channels is illustrated in the following diagram:
