We provide instruction in our documentation on how to quickly connect Symbl.ai to your Zoom meeting to generate transcriptions. The DTMF sequence is the sequence of keys you press to connect to the conference call once you have dialed in. The problem a user may encounter is the DTFM is likely specific to the configuration of the Zoom meeting you are attempting to join. This article serves to provide guidance on how to provide the correct DTMF.
Depending on the Zoom configuration there may be up to three values which need to be passed in the DTMF:
- Zoom MeetingId - This will always be required.
- Zoom ParticipantId - Optional & dependent on config. In the Zoom web interface this is found under settings/meeting/security/Require passcode for participants joining by phone
- Zoom Meeting Passcode - Optional & dependent on config. In the Zoom web interface this is found under settings/meeting/security/Meeting Passcode
The DTMF for dial in will always follow the order of meetingId -> ParticipantId -> Passcode. If for example Participant Id is disabled, but Passcode is enabled, the order will follow meetingId -> Passcode.
The input for each of these values is followed by a # symbol, and the DTFM wait character is a comma ','. We have found the sweet spot is two wait characters between each input. Additionally, if a ParticipantId is enabled in the Zoom config, it can be bypassed without input using #. Since the Symbl.ai dial in number is only used for transcription it shouldn't be necessary to include a specific ParticipantId in most use cases.
For the four possible scenarios you many configure the DTMF as follows:
meetingId, participantId, and passcode = "MEETING_ID#,,#,,MEETING_PASSCODE#"
meetingId, no participantId, and passcode = "MEETING_ID#,,MEETING_PASSCODE#"
meetingId, participantId, no passcode = "MEETING_ID}#,,#"
meetingId, no participantId, no passcode = "MEETING_ID}#"
