Record Custom IVR Prompts from a Phone

Sometimes you need to update an IVR greeting and the person who records it does not have SSH access. This extension lets them call in, record, listen back, and re-record until they are happy with it.

The dialplan

[internal]
; Dial *55 to record a custom prompt
exten => *55,1,Answer()
same => n,Playback(beep)
same => n(record),Record(custom-greeting:wav,3,30)
same => n,Playback(beep)
same => n,Playback(custom-greeting)
same => n,Background(vm-rerecord)
same => n,WaitExten(5)

; Press 1 to keep it, 2 to re-record
exten => 1,1,Playback(vm-saved)
same => n,Hangup()

exten => 2,1,Goto(*55,record)

exten => t,1,Playback(vm-saved)
same => n,Hangup()

exten => i,1,Goto(*55,record)

Record(custom-greeting:wav,3,30) records to /var/lib/asterisk/sounds/custom-greeting.wav. The 3 is seconds of silence before stopping, 30 is the maximum length. The caller hears their recording played back, then vm-rerecord ("press 1 to accept, 2 to re-record").

Using the recording in an IVR

Reference the file by name in any Playback() or Background() call:

[from-trunk]
exten => s,1,Answer()
same => n,Background(custom-greeting)
same => n,WaitExten(5)

Storing multiple prompts

Pass an argument to record different prompts:

exten => *551,1,Goto(recorder,s,1)
exten => *552,1,Goto(recorder,s,1)

[recorder]
exten => s,1,Answer()
same => n,Set(PROMPT=custom-prompt-${CALLERID(dnid)})
same => n,Playback(beep)
same => n(record),Record(${PROMPT}:wav,3,30)
same => n,Playback(beep)
same => n,Playback(${PROMPT})
same => n,Background(vm-rerecord)
same => n,WaitExten(5)

exten => 1,1,Playback(vm-saved)
same => n,Hangup()

exten => 2,1,Goto(s,record)

Dial *551 to record custom-prompt-*551.wav, *552 for a different one.
