Voicemail to email arrives without audio attachment

Scenario

Users receive voicemail notification emails, but the recording attachment is missing.

Recommended Resolution Path

1. Check mailbox size, transport security tools, and PBX voicemail-to-email settings.
2. Review whether the system is sending links instead of attachments after an update.
3. Trace one test voicemail end to end.
4. If mail security strips audio types, use a sanctioned exception rather than disabling protections broadly.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
