AI Voicemail Transcription & Summaries
AI voicemail transcription and one-line summaries - included in 3CX PRO and AI Edition. Every voicemail auto-transcribed, searchable, and emailed to you with a one-line summary.
What the email looks like
When a caller leaves a voicemail, you get an email roughly like this:
Subject: Voicemail from +61 4xx xxx xxx - Wants pricing for 25 users
Summary: Caller is the office manager at a 25-person dental practice
on the Mornington Peninsula. Wants to switch from Dialpad. Asked for
a callback this afternoon - said she'll be at the practice until 4pm.
Full transcript:
"Hi, this is Jenny from Bayside Family Dental. I'm calling to enquire
about your cloud phone systems. We've got about 25 people across two
sites and we're currently with Dialpad but it's been getting expensive

Why it works
Most voicemails are 10–60 seconds long. Listening to all of them in sequence is a 5–15 minute daily tax on every salesperson, manager and consultant. Reading the transcripts cuts that to seconds. The one-line summary cuts it further.
For sales teams, the second-order effect is bigger: voicemails get actioned instead of “I’ll listen to those tonight”. Lead response times drop. Conversion goes up.
