Send e-mail notification of new voicemail received

Hello everyone, I need to create this thing with the distro pbx 12. When a message is left on the answering machine should I get an email that alerts me. It can be done? I found in pbx wiki you have to set the email sending and receiving email. which is inserted in these extension fields? There are other places where you have to insert it?
Thanks for any help

Have you configured your SMTP mail server?

There is a problem, the guide is for version 13 of pbx gui, I have 12 and Admin-system admin I have the voice mail setup. How can I do?
