I get this error “Failed to connect to room with error: SIP error 403”, when I try to make a call from one iOS client to another while using twilio video sdk for swift.
If I'm correct in assuming these values are not placeholders for the real ones (it's a 403 error), you need to add your API credentials to your NodeJS script...
var ACCOUNT_SID = 'accountSid';
var API_KEY_SID = 'apiKeySid';
var API_KEY_SECRET = 'apiKeySecret';
var TWILIO_CONFIGURATION_SID = 'twilioConfigurationSid';
