How to record a message via Custom application

The Document describes how to record a custom message via Dialplan Custom application.

Created: May 2019


Use case

A user wants to change a standard IVR announcement from an external phone. To override restriction of not being able to dial feature code 74 as external caller - we can use configure it via Dialplan. 

Dialplan configuration

To the configuration, the previously recorded audio message is used ("test" in our example):

It is the original message that was recorded via Feature Code "Shared record" 74/ message recording option in WMS -> Sounds.  The idea is to replace it with the new one. When an external caller dials a DID to hit the Dialplan entry shown below - a beep sound is played and the recording starts immediately. You can also add "Play sound" application to announce that a message will be recorded after "Beep" sound (optional). 

To use this custom application, we need to build the following entry into the dial plan (matching a DID of course):

  • Custom application -> Record(/rw2/var/lib/callweaver/sounds/00000/test:alaw, 0,0,k)

where :

  • (/rw2/var/lib/callweaver/sounds/00000/) - path to the audio message

It is the default path and is used by default. If you place your recording in another folder - you will see /path/to/file differently. In this example file is stored at ~/00000/MusicOnHold/ folder

To verify the path, open your Dialplan and use "Play sound" application and choose your message from Sounds menu: 

  • test:alaw - the message name and format 
  • 0 - silence: seconds of silence allowed before the recording is stopped. If missing or 0, silence detection is disabled 
  • 0 - maxduration: the maximum duration of the recording in seconds. If missing or 0, the maximum duration is not set 
  • k - option: may be ‘skip’ to return immediately if the line is not up, or ‘noanswer’ to record even if the line is not up ( In our case this is k )

Available options:

  • a - extends the existing recording (doesn't replace it)
  • n - does not answer, but record anyway if line not yet answered
  • q - quiets (do not play a beep tone)
  • - skips recording if the line is not yet answered
  • t - uses alternate ‘*’ terminator key (DTMF) instead of default ‘#’
  • x - ignores all terminator keys (DTMF) and keep recording until hangup
  • k - keeps recorded file upon hangup
  • y - terminates the recording if *any* DTMF digit is sent

Note: the k option is used in our example dial plan and should likely be used in your case so that the person calling in to change the announcement can simple hang up OR press the # key to terminate the recording of the new announcement.
