%% This function is intended for use with audio_macro or manually started
%% media playback queued with a NoOp as the final action. This function
%% will wait forever for the (or any) NoOp event, collecting digits
%% while it does so. When the NoOp comes in the Timeout timer is started
%% (unless any digit has been pressed in which case the Interdigit
%% timer is used). Once the timer has expired the collected digits are
%% returned (possibly just an empty binary). However, digits can
%% be returned prior to the timer expiration if the last collected
%% digit is in the list of terminators (no returned if so). Digits
%% can also be returned if the number of collected digits exceeds the
%% MaxDigits.
%%
%% NOTICE: This function should NOT be called if ecallmgr control
%% queue does not have a NoOp queued. Otherwise this will block
%% execution untill the call is terminated.
