Asterisk VoiceMail Message Extension Append

This project is for you write a script or application that will cause the voice mail recipient’s extension number to be appended to the recorded message left by an outside caller when the message is saved in such a way that when the entire message to forward to the recipient’s email and the attached wav file is opened and played, he will hear the extension number the original message was for and the entire message as recorded by the outside caller. I’m not sure as to the best method to do this so I turn to GAF Pro’s for an answer. The idea is when a message is saved; asterisk forwards the record message to several people by email. The problem is played; there is no way to know who the message was originally for. This is the problem I’m trying to solve. But whatever your solution is, it must happen when saved and before the message is emailed. You can use existing prompts in asterisk sounds folder. Please ask question if you are not sure what I’m talking about Thanks, Bart
