Step 1. Create a separate Dialplan procedureprocedure 

First, create a procedure to deal with declined calls:

...

Step 2. Create audio files

Then add Create 3 audio files:

  1. priv-recordintro -> ask the caller to record their name, “please say your name after the tone, when done press #”
  2. priv-callpending -> announce the called user that there is a call coming, “this is a call from -recorded name- ““ (the caller's name recorded on the previous step is pronounced here)
  3. screen-callee-options -> let the called user know the options, “to accept the call press 1, to decline it press 2.                 “.

    it

     

    Warning

    It is important to have a couple of seconds of silence at the end of the audio to give the called user time to select an option.


All of the files need to be named as showed and be placed in /var/lib/callweaver/sounds/ folder

Note

Note: You can use mv (move), cd (change directory) or cp (copy) commands. For example: 

Code Block
mv /var/lib/callweaver/sounds/00000/priv-callpending.* /var/lib/callweaver/sounds

In this case, priv-callpending audio file is moved from /var/lib/callweaver/sounds/00000 directory to /var/lib/callweaver/sounds.


Step 3. Set up call screening

Finally, to dial the target extension, add the following Dialplan applications. In this case, all 3 digit extensions are screened.:

PDF avoid Pagebreak


  • Custom Application -> Dial(SIP/${EXTEN},,p)

Dial the user using call screening.

  • Jump to if -> “$> "${HANGUPCAUSE}"="16"

If the called user declines the call, the HANGUPCAUSE  is 16, proceed to Dialplan that Dialplan proceeds to the separate procedure that deals with declined calls ("screen" in our case, created in Step 1).

  • Hangup -> Reason 16

If the called user accepts the call, makes sure to hang up the application hang ups once the call is done.
