PBX — Voicemail Setup and Administration

Overview

The SipLive PBX uses Asterisk's built-in voicemail engine (app_voicemail). Voicemail boxes are provisioned per-extension in the voicemail table. Messages are stored as audio files and optionally emailed.

Enabling Voicemail on an Extension

1. Edit the extension in Communications → Extensions.
2. Enable the Voicemail checkbox.
3. Enter a Voicemail PIN (4–8 digits).
4. Enter the user's Email Address for voicemail-to-email.
5. Save — the voicemail row is created immediately.

Voicemail-to-Email

New messages are emailed with the audio attached (WAV or MP3), caller ID, and duration. Configure the SMTP relay in System → Email Settings.

Accessing Voicemail by Phone

• Dial *98 — unified mailbox access (prompts for mailbox number)
• Dial *97 — access your own mailbox directly
• Enter PIN, then: 1 = New messages, 2 = Old messages, 0 = Mailbox options (greetings)

Greetings

• Unavailable — Played when the extension doesn't answer.
• Busy — Played when the extension is on a call.
• Temporary — Overrides all others (vacation use). Set via phone menu: 0 → 4. Clear via: 0 → 5.

Greetings can also be uploaded as audio files via the admin portal.

Message Waiting Indicator (MWI)

The PBX sends PJSIP NOTIFY messages to light the voicemail lamp on desk phones. If MWI isn't updating, verify the mailbox exists:
