Connection settings
| Setting | What to enter |
|---|---|
| WebSocket server | wss://wss.securevoip.nz:7443 |
| SIP domain | sip.click2call.com.au |
| Username | The number or extension Login from Line Manager |
| Password | That line's password |

If your users are behind strict firewalls, a TURN server relays the audio. Click2Call's is optional, and you can use your own TURN or STUN servers instead.

Keep credentials off the page
Anyone who can see the line password can make calls on your account. Don't hard-code it in JavaScript that users can view. Fetch it from your own server after the user has logged in.
