Call Fabric Client Beta

This repository is a WIP and contains a limited release application using the new Call Fabric SDK from SignalWire.

It currently shows how to do inbound and outbound calling unsing a server-side token or via client-side authentication using OAUTH.

It contains two implementations, "full" and "minimal". We recommend starting from the minimal one and using the full application as a reference to add features as needed.

Getting started

Copy the env.example file into .env and fill it in with your SignalWire credentials. Set DEFAULT_DESTINATION to a resource in your space.

If you do not see the Resources tab in your space, please contact Support for enrollment in the beta program.

Getting a token

The first thing you need to do to use the SDK is requesting a token from SignalWire.

To make this work, you need to set up a client application that can request a token to act on behalf of a subscriber.

This is an example using CURL:

curl --location 'https://YOURSPACE.signalwire.com/api/fabric/subscribers/tokens' \
--form 'reference="foo"' \
--form 'password="dont-tell"' \
--form 'application_id="our-client-app-id"'
--user 'YOURPROJECTKEY:YOURTOKEN'

The reference field (aka subscriber) will be used in the future for inbound calling.

In the example application, we use fetch to retrieve the token.

Instantiate the client and call the destination

The initialization and calling phases are very similar to the previous version:

client = await SignalWire.SignalWire({
  token: _token,
  rootElement: document.getElementById('rootElement'),
})

const call = await client.dial({
  to: document.getElementById('destination').value,
  logLevel: 'debug',
  debug: { logWsTraffic: true },
})

await call.start()

For now, please run with debugging on to help with reporting issues.
