TwiML™ Voice:

The 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 , 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 are unreachable and ignored.

Using 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.

Verb Attributes

The verb supports the following attributes that modify its behavior:

Attribute NameAllowed ValuesDefault Value
reasonrejected, busyrejected

reason

attributes-reason page anchor

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. The default is rejected.

(information)

Info

This is a preference and what is actually played back is determined by the caller's service provider as they dictate what they want to playback to the caller.
