The Forum Post That Started It

We were browsing the HubSpot Community when we stumbled across this thread about meeting scheduler phone validation. The frustration was real:

"Phone numbers are critical for sales, marketing, and customer success teams—but right now HubSpot’s validation is limited. This often leads to messy data, bad formatting, and even non-existent numbers making it into our CRM."‍

This sort of problem is exactly why we built Clean Dial.

The Problem Users Are Facing

Your meeting scheduler is working perfectly, prospects are booking calls and your calendar is full.

Until your sales team starts dialing.

"The number you have dialed is not in service..."

Here is what is actually happening behind the scenes:

• Typos: Prospects accidentally mistype their numbers during booking.
• Burner Numbers: Leads provide fake or disposable phone numbers to avoid follow-ups.
• Inactive Lines: Numbers that look "valid" are actually disconnected or out of service.
• Formatting Issues: International prospects submit numbers without proper codes, making them undialable.

The Solution: HLR Network Lookups

We decided to fix this by going beyond simple formatting.

By using Clean Dial's HubSpot workflow action to perform an HLR Lookup, you can query the global telecom network to see if a number is actually live, when someone books a meeting:

Automatic HLR Query: The moment a meeting is booked, Clean Dial checks the carrier network to see if the phone is active.

Real-Time Status: The contact is instantly updated with an HLR Status (Live, Dead, or Absent) so your team knows who is reachable.

Identity Enrichment: Automatically identify the Phone Line Type (Mobile vs. Landline) and Carrier so you know exactly what kind of device you are calling.

Smart Formatting: The number is converted into your preferred format (E.164, National, etc.) so it works perfectly with your dialer.

A Native Solution for HubSpot Admins

Until HubSpot adds native network verification to their meeting schedulers, Clean Dial offers a seamless workflow-based workaround. You can set up automation to verify phone numbers the second they are submitted.

It gives you the data you need to identify which prospects are worth a high-priority call and which ones provided a dead line.

‍

How It Works

Setting up Clean Dial is simple:

1. Install the app.
2. Create a Workflow: Trigger the automation when a meeting is booked or a phone number is updated.
3. Add the HLR Lookup Action: Drop the Clean Dial action into your workflow.
4. Automate Your Routing: Use the HLR Status to flag "Dead" numbers for manual review or to remove them from your sales queue.
