DTMF Capture

The DTMF Capture node allows the collection of DTMF digits.

The DTMF data is temporally stored in a custom variable which can be used within the call flow during the call.

The optional setting [Persist DTMF] can be enabled to allow the DTMF data to be stored on the platform. This can then be retrieved using the Pulse Reporting Facility.

Branch	Mandatory	Description
Continue	Yes	This branch is taken when capture DTMF matched against user defined properties.
Max Attempts	Yes	The node reached the maximum number of unsuccessful attempts to match a DTMF against the user defined properties.
