8 Best Line2 Alternatives: AI, Pricing and Features

Line2 gives you a second phone number on your mobile, which works well for one person. Once a team shares numbers, needs CRM logging, or wants calls answered after hours, it runs out of road.

The best Line2 alternative depends on what you're growing into. Google Voice and Grasshopper suit solo owners on a budget. Quo suits small teams that work from their phones.

Aircall is the pick when you want AI Voice Agents answering calls alongside your team, with 250+ integrations and calls, texts, and WhatsApp on one number.

What is Line2, and why do teams switch?

Line2 is a second phone line app from J2 Web Services. It adds a business number to your mobile, so you can keep work and personal calls apart without a second device. Plans cost roughly $10 to $17 a month per line, depending on plan and billing.

That works for one person. Teams usually switch when they need:

• Someone, or something, to answer every call. Line2 rings your phone. It can't answer for you when you're busy or offline.

• Shared numbers. A support or sales line that rings several people, with routing and queues.

• CRM logging. Calls and notes saved to HubSpot, Salesforce, or your helpdesk without copy and paste.

• More channels. WhatsApp and SMS handled alongside calls, on the same number.

• Reporting. Call volume, missed calls, and response times for the whole team.

What should you look for in a Line2 alternative?

Start with what made Line2 feel small, then check each tool against these points:

1. AI call answering: can an AI agent answer, resolve, or route calls when nobody is free? Aircall's AI receptionist and AI Voice Agents do this on every plan.

2. Team features: shared numbers, IVR phone menus, call routing, and business hours.

3. Integrations: native connections to the CRM and helpdesk you already use. Aircall offers 250+ integrations.

4. Channels: calls, SMS, and WhatsApp, ideally on one number.

5. Pricing model: per seat, per minute, or per conversation, and what the AI costs on top.

6. Number porting: whether you can bring your existing number with you.

How do you switch from Line2 without losing your number?

Most providers, Aircall included, let you port an existing number, so customers keep calling the same one.

1. Check eligibility. Ask your new provider to confirm the number can be ported.

2. Get your account details. Collect your Line2 account information and the name on the account.

3. Keep Line2 active. Don't cancel until the port completes, or you could lose the number.

4. Submit the port request with your new provider and set up routing and AI answering while you wait.

5. Test, then cancel. Make test calls on the new system before closing your Line2 account.
