Call Verify

The Call Verify feature prompts callers to supply a keypress before connecting a phone call to an advertiser. This feature is helpful in blocking telemarketer phone calls, as well as being an extra step to qualify a caller before routing a call to the terminating phone number.

Be aware that this number feature cannot be used in conjunction with Advanced Call Routing configurations.

This feature is enabled via the Number Number Resource, rather than the 'call_route' level. All calls to the tracking number (regardless of call route) will be played the call verification notification.

The following fields are used in this request, and must be passed in your request:

Field	Value
enabled	true (feature may be disabled at a later date by submitting this value as:false)
key_press	A number between 1-9 the caller must enter on their phone's keypad to be connected to the advertiser
notification_text	Notification text that will be read to the caller that prompts them to supply a keypress Required if notification_file is not supplied
notification_file	Notification file GUID that corresponds to an audio file to be played to the caller prompting them for a keypress. Required if notification_text is not supplied For additional information on uploading and managing audio notification files, refer to API section: Notification File Management
