callUserDirectParameters

Send custom tags along with the push notification of an incoming call.

CallerID of the caller that will be displayed to the callee. Usage of whitespaces is not allowed. Normally it's some phone number that can be used for callback. IMPORTANT: test numbers rented from Voximplant can't be used as CallerID, use only real numbers.

Name of the caller that will be displayed to the callee. Normally it's a human-readable version of CallerID, e.g. a person's name.

Optional custom parameters (SIP headers) that should be passed with a call (INVITE) message. Custom header names have to begin with the 'X-' prefix. The "X-" headers can be handled by a SIP phone or WEB SDK (e.g. see the incomingCall event). Example: {'X-header':'value'}
