TwiML™ Fax: Twilio's Request

When Twilio receives a call to an Incoming Phone Number that has been configured as a Fax number, you will receive an HTTP request to the FaxUrl configured for that number. Your server should respond with TwiML that instructs Twilio how to proceed. The TwiML request will contain the following request parameters:

FaxSid The 34-character unique identifier for the fax
AccountSid The account from which the fax was sent
From The caller ID or SIP From display name
To The phone number or SIP URI of the destination
ApiVersion The API version used to send the fax, which for this API will be "v1"
