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 extensionA dialplan entry that matches a dialed number or pattern within a context and triggers a sequence of prioritized steps. 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.
