Enter phone number to leave message

Hi There,

Is there any feature or addon in FreePBX where I a user can be requested to “enter their number” using their touchpad before leaving a message? This would be useful for our call queues at peak times when we don’t want to keep people waiting too long. We are not particularly interested in the automated call-back function, simply getting the message in voicemail would be fine.

The reason why we need people to enter their numbers is that we deal mainly with international clients, and Caller ID is not always correct when it reaches us…
