The 10 Best Virtual Office Phone Number Apps in 2025

Virtual phone numbers aren’t tied to a specific device like a landline or mobile phone. Instead, they operate through the cloud and forward calls to an existing number you already use. This setup is often referred to as cloud telephony.

Unlike landlines that require you to stay in one place or smartphones that depend on being physically present, virtual numbers offer more flexibility. You can take calls from anywhere, on any device and without being tied to a fixed location.

So, how to get a virtual business phone number? 

Let’s take a look at 10 of the top virtual phone number providers available. We’ll review what they offer, how they compare, and which might fit your business best.

How to Pick the Right Virtual Office Phone Number Provider?

With so many options available, choosing the best virtual office phone number app can feel overwhelming. Here are the key aspects to consider when deciding which solution is right for your business:

1. Features That Match Your Needs

Start by listing the features that matter most to your team, like call recording, voicemail transcription, IVR, or integrations. Don’t overpay for bells and whistles you won’t use, but also make sure the essentials are covered.

2. Global Number Availability

If you plan to reach customers in different regions, check for local, toll-free, or international number support. A good provider should offer numbers in the countries you want to expand into, without breaking your budget.

3. User Experience & Support

A clunky dashboard or unreliable support can derail even the best phone system. Look for a platform with intuitive UX, a mobile app, and responsive support, especially if you don’t have an in-house IT team.

CloudTalk’s features, like call routing, analytics, and integrations, are super helpful for streamlining customer communication. Plus, the support team is always responsive and goes above and beyond to assist. It’s a game-changer for any business!

4. CRM & Workflow Integrations

If your business uses tools like Salesforce, HubSpot, or Zendesk, make sure your phone system integrates seamlessly. This can save tons of time and help you deliver a better customer experience.

5. Scalability and Pricing

Think long-term. Will the app grow with your team? Review pricing tiers and add-on costs for extra numbers, features, or agents. Transparent pricing is key, especially for startups or growing companies.

Best For:

Mid-market to enterprise teams with in-house technical resources that need programmable caller ID masking and custom VoIP workflows.

Powering Customer-Focused Communication

The right virtual phone number app offers flexibility, professionalism, and customer experience. As teams go remote and expectations rise, having a system that supports smart routing, CRM integration, and real-time insights is key.

Whether you’re a solo founder or scaling globally, choosing the best virtual office phone number can streamline operations and elevate your brand.
