Optionally play a sound file or a beep, then record audio and video from the channel.
chan | Channel to playback to/record from. | |
playfile | Filename of sound to play before recording begins. | |
recordfile | Filename to record to. | |
maxtime | Maximum length of recording (in seconds). | |
fmt | Format(s) to record message in. Multiple formats may be specified by separating them with a '|'. | |
duration | Where to store actual length of the recorded message (in milliseconds). | |
sound_duration | Where to store the length of the recorded message (in milliseconds), minus any silence | |
beep | Whether to play a beep before starting to record. | |
silencethreshold | ||
maxsilence | Length of silence that will end a recording (in milliseconds). | |
path | Optional filesystem path to unlock. | |
prepend | If true, prepend the recorded audio to an existing file and follow prepend mode recording rules | |
acceptdtmf | DTMF digits that will end the recording. | |
canceldtmf | DTMF digits that will cancel the recording. | |
skip_confirmation_sound | If true, don't play auth-thankyou at end. Nice for custom recording prompts in apps. |
-1 | failure or hangup | |
'S' | Recording ended from silence timeout | |
't' | Recording ended from the message exceeding the maximum duration, or via DTMF in prepend mode | |
dtmfchar | Recording ended via the return value's DTMF character for either cancel or accept. |
Same logic as above.

digits | This is a string of characters representing the DTMF digits to be sent to the channel. Valid characters are "0123456789*#abcdABCD". Note: You can pass arguments 'f' or 'F', if you want to Flash the channel (if supported by the channel), or 'w' to add a 500 millisecond pause to the DTMF sequence. | |
between | This is the number of milliseconds to wait in between each DTMF digit. If zero milliseconds is specified, then the default value of 100 will be used. | |
duration | This is the duration that each DTMF digit should have. |
