Missed Call Text Back SMS

🎯 Purpose:
To automatically send a text message when a contact calls but doesn’t leave a voicemail, using a custom trigger that works with your myCRMSIM SIM, not LeadConnector.

🧠 Background (Why This Matters)
The native HighLevel Missed Call Text Back only works with LeadConnector or Twilio. That’s no good for myCRMSIM SIM users. 😤

To fix this, we use a custom trigger that watches for a specific SMS response from your carrier, then sends a personalized text back to the caller — only when they hang up without leaving a voicemail.

🛠️ Prerequisites

✔️ myCRMSIM snapshot installed
✔️ Your SIM plan must send a missed call SMS notification
✔️ Access to workflows + SMS settings
✔️ Customize the trigger phrase in the workflow

✅ Step-by-Step Instructions

📌 Step 1: Verify Your Carrier Sends a Missed Call SMS

You MUST receive a text message when someone calls and doesn’t leave a voicemail.
For example, Australian SIMs (like Amaysim) send this SMS:

“No voicemail messages left. For more info on this feature, free call 147 from your mobile phone.”

💡 You can’t use this workflow unless your plan sends that kind of SMS.

If you’re unsure, call your SIM number from another phone, don’t leave a message, and check what auto-reply SMS gets sent. That’s the text you’ll use to trigger the workflow.

🧩 Step 2: Update the Trigger Phrase

Open the workflow → Find the trigger step:

• Trigger Type: "Reply Channel SMS"

• Condition: "Contains phrase"

Update the phrase to match a unique, consistent part of the missed call SMS your provider sends.

🚫 Don’t include phone numbers or dynamic parts
✅ Do include a static sentence fragment (like: “no voicemail messages left”)

🛠 Step 3: What the Workflow Does

Once triggered, the workflow:

1. ✍️ Adds a note to the contact: “Tried to call but didn’t leave a voicemail.”

2. 👤 Assigns to a user (update this to your actual team member)

3. ⏱ Waits 30 seconds (lets the system breathe)

4. 📲 Sends SMS:

   "Hey! Sorry I missed your call. I’m currently tied up but happy to text — how can I help?
   – {{user.full_name}}, {{location.name}}"

5. ⏳ Waits 60 minutes:
   This prevents multiple SMS sends if someone tries to call several times back-to-back.

🧠 The workflow settings allow re-entry, but this wait step ensures the same contact doesn’t get spammed within a short time window.

⚙️ Settings Recap

✔️ Trigger Phrase matches the missed call message (custom to your provider)
✔️ Wait Timer delays re-triggering (default = 60 min; you can adjust)
✔️ SMS Content personalized with user and location info
✔️ Re-Entry Allowed only after timeout passes

📢 Final Notes

‣ If your provider doesn’t send missed call SMS notifications — this won’t work 😢
‣ You can request that your SIM provider enable voicemail notifications if not active
‣ Make sure you’re using a SIM provider that supports this automation-style reply

🙌 Pro Tip
Test it by calling your SIM number, hanging up without a voicemail, and watching if the SMS arrives. If it doesn’t — double-check your carrier setup and trigger phrase.
