<Reject> verb rejects an incoming call to your Twilio number without billing you.
This is very useful for blocking unwanted calls.
If the first verb in a TwiML document is
<Reject>, Twilio will not pick up the call.
The call ends with a status of 'busy' or 'no-answer', depending on the
verb's 'reason' attribute. Any verbs after
<Reject> are unreachable and ignored.
Note that using
<Reject> as the first verb in your response is the only way
to prevent Twilio from answering a call. Any other response will result in an
answered call and your account will be billed.
<Reject> verb supports the following attributes that modify its behavior:
|Attribute Name||Allowed Values||Default Value|
The reason attribute takes the values "rejected" and "busy." This tells Twilio what message to play when rejecting a call. Selecting "busy" will play a busy signal to the caller, while selecting "rejected" will play a standard not-in-service response. If this attribute's value isn't set, the default is "rejected."
You can't nest any verbs within
<Reject> and you can't nest
<Reject> in any other verbs.
<Reject> won't work when handling calls to the (deprecated) Twilio Sandbox
number. Twilio must pick up the call to ask for the pin, at which point it's
too late to reject.
