Outgoing Caller IDs

(warning)

Warning

NOTE: The order of the columns in the CSV is not defined and may change when new fields are added to the API response. Your application design should be resilient to changes in the order of the columns in the CSV response.

An OutgoingCallerId instance resource represents a single verified number that may be used as a caller ID when making outgoing calls via the REST API and within the TwiML <Dial> verb. The OutgoingCallerIds list resource represents the set of an account's verified phone numbers.

HTTP POST

Adds a new CallerID to your account. After making this request, Twilio will return to you a validation code and Twilio will dial the phone number given to perform validation. The code returned must be entered via the phone before the CallerID is added to your account.

The following parameters are accepted:

Required Parameters

Parameter	Description
PhoneNumber	The phone number to verify. Should be formatted with a '+' and country code e.g., +16175551212 (E.164 format). Twilio will also accept unformatted US numbers e.g., (415) 555-1212, 415-555-1212.

Optional Parameters

Parameter	Description
FriendlyName	A human readable description for the new caller ID with maximum length 64 characters. Defaults to a nicely formatted version of the number.
CallDelay	The number of seconds, between 0 and 60, to delay before initiating the verification call. Defaults to 0.
Extension	Digits to dial after connecting the verification call.
StatusCallback	A URL that Twilio will request when the verification call ends to notify your app if the verification process was successful or not. See StatusCallback parameter below. Note: The StatusCallback URL has a limit of 1000 characters.
StatusCallbackMethod	The HTTP method Twilio should use when requesting the above URL. Defaults to `POST`.

This will create a new CallerID validation request within Twilio, which initiates a call to the phone number provided and listens for a validation code. The validation request is represented in the response by the following properties:

Response Properties

Property	Description
AccountSid	The unique ID of the Account to which the Validation Request belongs.
PhoneNumber	The incoming phone number being validated, formatted with a '+' and country code e.g., +16175551212 (E.164 format).
FriendlyName	The friendly name you provided, if any.
ValidationCode	The 6 digit validation code that must be entered via the phone to validate this phone number for Caller ID.
CallSid	The unique id of the Call created for this validation attempt.

StatusCallback Parameter

After the verification call ends, Twilio makes an asynchronous HTTP request to the StatusCallback URL if you provided one in your API request. By capturing this request, you can determine when the call ended and whether or not the number called was successfully verified.

Twilio passes the same parameters to your application in its asynchronous request to the StatusCallback URL as it does in a typical status callback request. The full list of parameters and descriptions of each are in the TwiML Voice: Twilio's Request documentation.

The verification status callback request also passes these additional parameters:

Parameter	Description
VerificationStatus	Describes whether or not the person called correctly entered the validation code. Possible values are `success` or `failed`.
OutgoingCallerIdSid	If the verification process was successful, the SID value of the newly-created OutgoingCallerId resource for the verified number.

Add an Outgoing Caller ID

Here are a typical request and response. Typically, you would present the validation code from the response to the user who is trying to verify their phone number. Adding an Outgoing Caller ID via the API has the same result as verifying a number via the Twilio console.
