> Say you have a DTMF hook that triggers on the DTMF sequence '*1'.
> After you press '*' the bridge channel waits for more digits to see if a '1' is coming.  Unfortunately, while the bridge channel is waiting for more digits, it is not passing normal audio frames from the bridge in the other direction.  The blocked audio frames result in a disconcerting break in audio continuity either while listening to a recording or the person from the other end.
> The wait happens in the {{bridge_channel.c bridge_channel_feature()}} function when {{ast_waitfordigit()}} is called.
> The time to wait for more digits is configured by the features.conf featuredigittimeout option.
