How does it work?

Voicemail is implemented via Asterisk’s built-in app_voicemail module. Configuration is written to voicemail.conf. If a call is not answered (e.g., via No Answer forwarding), voicemail picks up.

• SMTP integration – Emails via the configured SMTP server
• Audio format – WAV files playable directly in the browser
• PIN protection – Mailbox accessible only with PIN (phone or web)

Setup

Step	Action
1	Configure SMTP under Settings → Email
2	Edit extension → enable Voicemail
3	Set PIN and email address for notifications
4	Configure No Answer forwarding to voicemail
