This guide covers everything you need to get in-app calling working in lemlist: connecting or buying a phone number, configuring your settings, managing calling credits, and troubleshooting common issues.
Prerequisites
You have access to lemlist Settings and Call settings (team permissions may apply).
Your leads have valid phone numbers (otherwise the call button won't be available).
You have enough calling minutes/credits to place calls (explained below).
If you want CRM sync, your CRM integration is connected (HubSpot, Salesforce, or Pipedrive).
Step 1: Set up a phone number
Go to Settings → Call settings (or Settings → Sending settings → Phone numbers) to manage your phone numbers.
Option A — Connect your own phone number
You can connect only one personal phone number to lemlist at a time.

Go to Settings → Call settings, then click + Add a number.
Select Connect phone numbers.
Select your country, enter your phone number, then click Next.
Copy the 6-digit code shown on screen.
Answer the verification call and enter the 6-digit code using your phone keypad.
When verification completes, you'll see a confirmation message.
Important: If you want to use a different personal number later, you'll need to replace the currently connected one — lemlist doesn't support connecting multiple personal phone numbers at the same time.
Option B — Buy a phone number from lemlist
If you want a dedicated number for outreach, you can purchase a local number through lemlist. This can help improve trust and pickup rates when calling specific regions.
Supported countries & requirements (buying numbers)
Country | Available Numbers | Special Requirements |
🇺🇸 United States | Landline only | No restrictions |
🇫🇷 France | Mobile & Landline | Must provide company registration details |
🇬🇧 United Kingdom | Mobile & Landline | Must provide business documents |
🇩🇪 Germany | Landline only | Must have a company in Germany |
🇧🇪 Belgium | Landline only | Must have a company in Belgium |
🇨🇦 Canada | Mobile & Landline | No specific local residency or business documentation required |
🇦🇺 Australia | Mobile & Landline | Must provide business documents |
🇮🇪 Ireland | Landline only | Must provide business documents |
🇳🇱 Netherlands | Mobile only | Must provide business documents |
Go to Settings → Call settings, click + Add a number, then select Buy phone numbers.
Select the country and the type of line (for example, Landline).
Pick the number you want, then click Buy.
Confirm the purchase (for example, click Buy 1 number).
Note: Depending on the country, you may be prompted to provide additional business information or documents due to local telecom regulations.
Step 2: Configure number settings
After you connect or buy a number, configure how it behaves so calls are consistent across your team (labeling, recording defaults, forwarding rules).
In Settings → Call settings, click the settings (gear) icon next to the number you want to configure.
Update the Number label, optionally set Forward incoming calls to, and enable/disable Automatic outgoing call recording (and other toggles, depending on your plan and configuration).
Step 3: Understand minutes & credits
lemlist in-app calling uses a credit-based system to measure call time. Every call deducts minutes from your available balance.
Monthly call allowance by plan
Multichannel Expert plan: 100 calling minutes per user/month
Enterprise plan: 300 calling minutes per user/month
How credits work
1 call minute = 4 credits
10 minutes = 40 credits
50 minutes = 200 credits
Check minutes and buy more
In Call settings, review your remaining calling minutes and click Buy additional minutes when needed.
If you have enough credits, confirm the purchase.
If you don't have enough credits, you'll be prompted to buy more credits first.

Troubleshooting
Calling is unavailable or calls fail
Root cause: Provider incident or outage.
Fix: Check Twilio's public status page (status.twilio.com) for ongoing incidents. Extended scenarios include: calls hanging up immediately, calls dialling but not ringing, or the call feature being greyed out.
Blocked numbers: Certain numbers may be blocked due to security or compliance flags (e.g. high-risk prefixes such as 085 numbers in the Netherlands). Verify the number is not flagged as high-risk.
Can't click the phone icon to call a lead
Root cause: The lead doesn't have a phone number, or you don't have a connected/bought number set up.
Fix: Add a phone number to the lead, and confirm your calling setup in Settings → Call settings.
Can't connect another personal number
Root cause: lemlist supports only one connected personal phone number at a time.
Fix: Remove or replace the currently connected personal number before connecting a new one.
Run out of minutes mid-day
Root cause: Your plan allowance is used up.
Fix: Buy additional minutes in Call settings using credits.
Optional: Use Ringover instead of the lemlist dialer
If your team uses Ringover, you can disable the lemlist dialer while keeping lemlist outreach workflows.
Go to Settings → Call settings.
Scroll to Disable lemlist dialer and toggle it on.
This option can be customized at both the user and team levels.
