Turn every hang-up into a two-way SMS conversation.
Most callers who reach voicemail hang up before the beep. With Missed-Call Auto-SMS and reusable SMS Templates, Premium Voicemail texts them immediately from your Australian mobile number while kept messages continue flowing to your live inbox and team alerts.
Reusable SMS Templates
Write a message once, reuse it across every mailbox. Personalise it with the caller's number, the number they dialled and more.
Sent From Your Mobile Number
The SMS comes from an Australian mobile number on your account, so callers can reply straight to you.
How Missed-Call Auto-SMS works in 4 simple steps.
Set up your template once in MyAccount and switch on Auto-SMS on any mailbox that needs automatic caller follow-up.
01
Create an SMS template
In MyAccount go to Premium Features → Voicemail → SMS Templates and select New template. Give it a name and write your message.
02
Personalise with placeholders (optional)
Tap a placeholder chip to drop it into your message. Each one is filled in automatically for every call (see the list below).
03
Turn on Auto-SMS for a mailbox
Edit a mailbox, open Alerts & Notifications, switch on Auto-SMS Caller on Missed Call, then choose your template and the mobile number to send from.
04
Save - that's it
From now on, missed callers to that mailbox are texted automatically.
Placeholders you can use in SMS Templates.
Drop any of these five placeholders into your template and Premium Voicemail fills them in automatically for each missed call.

Missed-Call Auto-SMS & SMS Templates feature details.
Built with smart safeguards so you only text real Australian mobile callers, avoid duplicate message floods, and stay in complete control per mailbox.
SMS Templates library
- One library per account, shared by every voicemail mailbox.
- Template name: 1-128 characters. SMS message: up to 1,000 characters.
- A live counter shows the character count, whether the message is standard (GSM-7) or Unicode (UCS-2), and the estimated number of SMS segments.
- Edit or delete a template at any time. Before you delete, MyAccount shows how many mailboxes use it.
Auto-SMS Caller on Missed Call
- Set per mailbox - switch it on only where you want it.
- Pick the template and the sender number independently for each mailbox.
- Separate from your existing owner alerts: those notify you; this feature texts the caller.
Who receives the SMS
- Only callers with an Australian mobile number (starting
04/+614). - Withheld/private numbers, landlines and international callers are skipped - no SMS is sent and no charge applies.
- The same caller is texted at most once every 5 minutes, so repeat missed calls don't trigger a flood of messages.
Sender number
- Must be an Australian mobile number on your account (
04...). - 13, 1300, 1800 and landline numbers can't send SMS and aren't offered.
- Because the SMS comes from your account's mobile number, callers can reply directly.

Everything included in CrazyTel Premium Voicemail.
Start with a $1/month mailbox and combine Missed-Call Auto-SMS, custom greetings, free email delivery, AI transcription and webhook automation.
Missed-Call Auto-SMS
Automatically text Australian mobile callers who hang up during your greeting or leave a recording under 1 second, using reusable SMS templates and your own 04 number.
Named mailboxes
Create Sales, Reception, After Hours or On-call Support mailboxes. Assign one or multiple numbers and keep message history together.
Professional greetings
Use the default greeting or upload WAV and MP3 audio to a reusable greeting library for business hours, holidays and campaigns.
Live inbox
See new messages as they arrive. Filter by mailbox, number or status, then play recordings and check retention expiry.
Optional AI transcription
Read the message before listening. Full transcripts can appear in the portal and configurable previews can be sent by email or SMS.
Email and owner SMS alerts
Email alerts are included free. Add owner SMS alerts for mobile-first teams, with multiple recipients, secure listen links and missed-call notifications.
Webhooks for follow-up
Send signed HTTPS events to a CRM, helpdesk or workflow when a voicemail arrives, a transcript completes or a caller hangs up.
Secure listening
Portal playback and email or SMS links use authorised, short-lived access instead of permanent public recording URLs.
Retention & audit control
Choose a retention period up to 180 days and review playback, download and mailbox activity across shared teams.
One mailbox, many business moments.
Use voicemail as a safety net for a small business or as a deliberate step in a larger call flow.
Small business
Text back callers who hang up
A tradie or clinic misses a call while with a client. If the caller hangs up on the greeting, Auto-SMS texts them from the business 04 number; if they leave a message, the owner gets the transcript.
Shared sales
Turn overnight enquiries into leads
A branded Sales mailbox sends an instant text-back to callers who hang up and emails full recordings and transcripts to the sales team.
After hours
Give callers clear next steps
A custom greeting explains opening hours and emergency options while an after-hours SMS template confirms when your team will call back.
Queue overflow
Protect busy support teams
When a queue reaches its limit, offer voicemail, text back callers who hang up early, and create a follow-up task through a webhook.
Example flow: Main business number → business-hours check → Ring Group → Sales Voicemail (with Auto-SMS Caller on Missed Call enabled) when unanswered.
