             Summary: Crashes due to "channel.c: Resolve issue with receiving SIP INFO packets for DTMF"
                 Key: ASTERISK-29068
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29068
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_voicemail, Core/Channels
    Affects Versions: 16.13.0, 16.12.0, 16.11.0, 16.10.0, 16.9.0, 16.8.0, 16.7.0
            Reporter: Andre Heider


When accessing the voicemail and using the phone's keys to navigate, asterisk crashes every time.

The greeting messages plays fine, but upon the first pressed key the whole asterisk process ends/crashes without error message. It doesn't matter if there're messages, using '0' for 'mailbox options' is sufficient to reproduce this.

Reverting said commit on top of 16.13.0 fixes the issue and voicemails works as expected.
