             Summary: Bridge DTMF hooks: Audio doesn't pass when waiting for more matching digits.
                 Key: ASTERISK-24447
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24447
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/Bridging
    Affects Versions: 12.6.1
            Reporter: Richard Mudgett


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.
