What is VoIP Number Software for Business?
VoIP (Voice over Internet Protocol) number software lets businesses assign virtual phone numbers and route calls over the internet rather than traditional copper lines. Unlike legacy PBX (Private Branch Exchange) systems that require on-site hardware, VoIP platforms run in the cloud — and if you’re evaluating VoIP phones for business, your team can call from a laptop, mobile, or browser with no physical setup required.
FreJun takes under 2 minutes to set up. No credit card required for the trial, no hardware to install. Just connect your CRM and your team can start making calls immediately.

How Do You Simplify Business Calls with VoIP Numbers?
Simplifying business calls with VoIP starts with centralizing your numbers, devices, and call data in one place. When your team can call from any device, see call history in the CRM, and get transcripts automatically, the manual overhead disappears. The right VoIP number software for business handles all of this without requiring IT involvement or hardware purchases.
“After working with 500+ sales teams over 8 years, the single biggest friction point we see is not the calling itself but the logging. Reps spend 15 to 20 minutes per day manually updating CRM records after calls. When you remove that with automatic call logging and transcription, connect rates go up because reps spend that time actually dialing instead of typing.”
— Subhash Kalluri, Co-Founder and CEO, FreJun
Cloud-based VoIP numbers are easy to assign, manage, and scale. Whether it’s one line for a solo founder or a dozen numbers across sales and support teams, everything stays centralized with intuitive controls. Users can make and receive calls from any device, with instant access to transcripts, notes, and CRM data. The platform handles compliance and call quality automatically, so your team focuses on conversations rather than configuration.
How to Set Up VoIP Number Software for Your Business
Setting up VoIP number software takes less time than most teams expect. Here are the core steps that apply across most platforms, including FreJun.
- Choose your plan and sign up: Select a plan based on your team size and required features. Most platforms, including FreJun, offer a free trial so you can test before committing.
- Assign virtual numbers: Pick local, toll-free, or international numbers for each team member or department. FreJun lets you do this from the dashboard in under a minute.
- Connect your CRM: Integrate with your existing CRM (Salesforce, HubSpot, Zoho, or others) so calls log automatically without manual entry.
- Configure call routing: Set up IVR menus, call queues, or direct routing rules so incoming calls reach the right person every time.
- Enable call recording and transcription: Turn on automatic recording and AI transcription so every conversation is captured and searchable.
- Train your team: Most VoIP platforms have browser extensions or mobile apps, so onboarding takes under 30 minutes per rep.

We recommend FreJun over other platforms on this list when your team needs AI automation and CRM sync working together out of the box. The combination of auto-dialing, transcription, and direct CRM logging is hard to match at this price point.
Pricing: Standard: from $14.49 per user, per month. Professional: from $16.69 per user, per month.

2. RingCentral
Why Choose RingCentral?
RingCentral is a strong choice for large enterprises that need voice, video, and messaging unified under one platform. It handles advanced call distribution, call forwarding, and analytics at scale, and it connects with tools like Microsoft Teams and Salesforce, so large teams can keep their existing workflows intact.
That said, RingCentral’s pricing starts at $30 per user per month, which makes it harder to justify for smaller teams. If you’re running a team of under 20 reps, the cost-to-feature ratio tips in favor of lighter platforms like FreJun or Nextiva. For global enterprises with complex routing needs, though, RingCentral is hard to beat.
Key Features:
- Unified communication for voice, video, and chat in one interface.
- AI-powered analytics to track and improve customer interactions.
- Call recording and voicemail transcription for documentation and compliance.
- Mobile and desktop apps for calling from anywhere.
- 99.999% uptime SLA with 24/7 customer support.
Pricing: Basic plan starts at $30/user/month.
G2 Rating: 4.0/5
Best For: Large enterprises needing unified voice, video, and messaging at scale.
3. Grasshopper
Why Choose Grasshopper?
Grasshopper is a virtual phone system built for small businesses and solopreneurs who need a professional business line without the complexity of a full VoIP platform. It handles call forwarding, voicemail, and auto-attendant well, so a one-person team can project the same phone presence as a larger company.
The biggest limitation is that Grasshopper lacks the AI features and CRM integrations that growing teams need. It’s a solid starting point, but most teams outgrow it once they hit 5 or more reps and need call analytics or CRM sync.
Key Features:
- Virtual phone numbers with local, toll-free, and vanity options.
- Auto-attendant for professional call routing and greetings.
- Call forwarding to mobile and desktop devices.
- Voicemail transcription for quick message review.
- Simple pricing with unlimited extensions.
Pricing: Starts at $14/month.
G2 Rating: 4.0/5
Best For: Startups and solopreneurs needing a simple virtual business line.
4. Nextiva
Why Choose Nextiva?
Nextiva is a strong fit for growing businesses that need voice, email, and chat in one place without the enterprise price tag of RingCentral. Its analytics and automation tools give managers real insight into customer interactions, while affordable pricing plans make it accessible for teams scaling from 10 to 100 users.
Nextiva’s onboarding is straightforward, and the platform’s reliability is well-documented. The biggest trade-off is that its AI features are less mature than FreJun’s, so teams that prioritize call transcription and sentiment analysis may find it limiting.
Key Features:
- Unified communication for voice, email, and chat.
- AI-powered analytics to track and improve customer interactions.
- Call recording and voicemail transcription for documentation.
- Mobile and desktop apps for calling from anywhere.
- Reliable uptime with 24/7 customer support.
Pricing: Basic plan starts at $20/user/month.
G2 Rating: 4.5/5
Best For: Growing businesses needing a scalable, affordable communication platform.
5. Cisco Webex
Why Choose Cisco Webex?
Cisco Webex Calling is the go-to choice for enterprises in regulated industries where security and compliance are non-negotiable. It integrates with the full Webex suite, giving teams a unified experience across voice, video, and collaboration tools, while enterprise-grade encryption and PSTN (Public Switched Telephone Network) connectivity cover global reach.
The most common feedback from teams using Webex is that the security features are excellent but the interface takes longer to learn than lighter platforms. If your team is in finance, healthcare, or government, or a legal practice — VoIP for law firms is a particularly strong use case — the compliance features justify the learning curve.
Key Features:
- HD voice and video communication with enterprise-grade quality.
- End-to-end encryption and compliance features for regulated industries.
- Integration with Webex Teams for enhanced collaboration.
- Global reach with PSTN connectivity across major markets.
- Scalable plans built for large enterprise deployments.
Pricing: Basic plan starts at $15.30/user/month.
G2 Rating: 4.5/5
Best For: Enterprises in regulated industries that need secure VoIP with full collaboration tools.
6. 8×8
Why Choose 8×8?
8×8 is the strongest option on this list for businesses with international calling needs. It offers unlimited calls to over 40 countries, which makes it a practical choice for teams with customers or offices spread across multiple regions. The platform combines VoIP, video conferencing, and team messaging in one interface, with AI-powered analytics built in.
The biggest trade-off with 8×8 is pricing. At $24 per user per month for the base plan, it’s more expensive than FreJun or Zoom Phone. But if your team makes frequent international calls, the unlimited calling model pays for itself quickly compared to per-minute billing.
Key Features:
- Unlimited international calling to over 40 countries.
- AI-powered analytics to improve customer engagement.
- HD video conferencing with screen sharing.
- Scalable plans for small businesses and global enterprises.
- End-to-end encryption across all communication channels.
Pricing: Flexible plans starting at $24/user/month.
G2 Rating: 4.0/5
Best For: Businesses with global operations needing unlimited international VoIP calling.
7. Vonage Business Communications
Why Choose Vonage?
Vonage Business Communications is the right choice for tech-savvy teams that need to build custom calling workflows. Its extensive API library lets developers connect Vonage to almost any internal system, while built-in features like IVR (Interactive Voice Response), call queuing, and a virtual receptionist handle day-to-day call management. It integrates directly with Salesforce, HubSpot, and other major CRMs.
The most common challenge teams report with Vonage is that the API flexibility requires developer time to set up properly. If your team doesn’t have engineering resources, you’ll get more value from a platform like FreJun that comes pre-integrated with major CRMs out of the box.
Key Features:
- Extensive API support for building custom communication workflows.
- Advanced IVR and call routing for professional customer management.
- Direct integration with Salesforce, HubSpot, and other CRMs.
- Scalable plans for growing teams.
- 24/7 customer support with detailed documentation.
Pricing: Mobile Plan starts at $19.99/user/month.
G2 Rating: 4.3/5
Best For: Tech-savvy businesses that need custom VoIP workflows and API-level control.
8. Ooma Office
Why Choose Ooma?
Ooma Office is the most budget-friendly option on this list for small businesses that need reliable calling without a long-term contract. Its virtual receptionist handles automated call routing, and the setup is simple enough that most teams are live within an hour. There are no hidden fees and no hardware requirements beyond a standard internet connection.
The trade-off is that Ooma lacks the AI features and deep CRM integrations that growing teams need. It’s a practical choice while your team is small, but most businesses switch to a more capable platform once they hit consistent call volume and need analytics.
Key Features:
- Virtual receptionist for automated call handling and routing.
- Call blocking and routing to manage incoming calls efficiently.
- Mobile app for managing calls from anywhere.
- Simple pricing with no contracts or hidden fees.
- Built-in failover for reliable call quality.
Pricing: $20/user/month.
G2 Rating: 4.6/5
Best For: Budget-conscious small businesses that need a reliable VoIP system without contracts.
9. Zoom Phone
Why Choose Zoom Phone?
Zoom Phone is the natural choice for teams already using Zoom Meetings as their primary video platform. It adds high-quality VoIP calling to the Zoom ecosystem, so your team can switch between voice and video without changing apps. Global PSTN coverage means international calls work reliably, and the $10 per user per month starting price makes it one of the most affordable options on this list.
The biggest limitation is that Zoom Phone works best when your whole team is already in the Zoom ecosystem. If you’re using a different video platform or need deep CRM automation, a platform like FreJun will give you more calling-specific features at a comparable price.
Key Features:
- Enterprise-grade PSTN connectivity with global reach.
- Direct integration with Zoom Meetings for unified voice and video.
- Voicemail transcription and call recording for documentation.
- Scalable plans for businesses of any size.
- Security features to protect sensitive call data.
Pricing: Starts at $10/user/month.
G2 Rating: 4.5/5
Best For: Teams already using Zoom for video who want to add VoIP calling in the same platform.
Which VoIP Number Software Should You Choose for Your Business?
The right VoIP number software for business depends on your team size, calling volume, and how much you need AI and CRM automation. Here’s a direct breakdown to help you decide without second-guessing.
If your team makes high-volume outbound calls and needs every call logged automatically in your CRM, FreJun is the strongest choice. The auto-dialer, AI transcription, and direct CRM sync work together in a way that no other platform on this list matches at the $14.49 price point. Most teams that switch to FreJun from a legacy system see measurable improvements in daily call volume within the first two weeks.
If you’re a solo founder or a team of two or three people, Grasshopper or Zoom Phone give you a professional business line without paying for features you won’t use yet. Both are easy to set up and affordable enough to start with before upgrading.
For enterprises with strict security requirements, Cisco Webex is the right call. For global teams making frequent international calls, 8×8’s unlimited calling model saves money over per-minute billing. The biggest mistake most teams make is choosing a platform based on brand recognition alone rather than matching features to their actual workflow, exploring the right VoIP business solutions upfront saves time and switching costs later. VoIP number software for business works best when it fits how your team already operates, not the other way around.

Frequently Asked Questions About VoIP Number Software for Business
What is a VoIP number and how does it work?
A VoIP number is a virtual phone number that routes calls over the internet rather than traditional copper phone lines. When you dial out or receive a call, the audio is converted into data packets, transmitted over your internet connection, and reassembled at the other end. Because there’s no physical line required, you can use the same number from a laptop, mobile phone, or browser. FreJun provides cloud-based VoIP numbers that work reliably for business calls even on mobile data connections.
Why should I use a VoIP number instead of a regular phone line?
VoIP numbers cost significantly less than traditional landlines, since you’re not paying for physical infrastructure or per-minute rates on most plans. They’re also more flexible: your team can call from any device, from any location, while keeping the same business number. VoIP platforms like FreJun add features that landlines can’t match, such as CRM sync, call recording, and AI transcription, so your team gets more value from every call rather than just a dial tone.
Can I use a VoIP number to support multiple departments?
Yes, and this is one of the strongest use cases for VoIP. With FreJun, you can assign separate VoIP numbers or extensions to sales, support, and operations teams, all managed from a single dashboard. Each team gets its own call routing rules, voicemail, and analytics, so managers can track performance by department without mixing data. You can add or remove numbers as your team grows without any hardware changes.
Are VoIP numbers reliable for daily business use?
Modern VoIP platforms are highly reliable when running on a stable internet connection. Most enterprise-grade providers, including FreJun, RingCentral, and Nextiva, publish uptime SLAs of 99.9% or higher. Call quality depends on your internet bandwidth, but most business broadband connections handle VoIP calls without any issues. FreJun also includes smart call routing so that if one connection path has quality issues, calls are automatically rerouted to maintain audio clarity.
Is it possible to get a local or international VoIP number?
Yes. Most VoIP platforms on this list offer both local and international virtual numbers. FreJun provides local numbers for specific cities or regions as well as international numbers, so your business can have a local presence in any market without a physical office. This is particularly useful for sales teams calling into new geographies, since local numbers typically see higher answer rates than international or unknown numbers.
Will a VoIP number integrate with my existing CRM?
Yes, and CRM integration is one of the key reasons businesses switch to VoIP. FreJun integrates directly with Salesforce, HubSpot, Zoho, Pipedrive, Leadsquared, and other major CRMs, including Microsoft Dynamics 365 VoIP calling so every call is logged automatically without manual entry. RingCentral and Vonage also offer strong CRM integrations, though Vonage requires more developer setup for custom workflows. When evaluating platforms, check whether the integration is native or requires a third-party connector, since native integrations are more reliable.
Is setting up a VoIP number complicated?
Not with modern cloud-based platforms. FreJun’s setup takes under 2 minutes: sign up, choose your number, connect your CRM, and your team is ready to call. There’s no hardware to install and no IT team required. Grasshopper and Ooma Office are similarly straightforward for small teams. The platforms that require more setup time are those with deep API customization, like Vonage, where the flexibility comes with additional configuration work upfront.
How much does VoIP number software cost for a small business?
VoIP number software for business typically ranges from $10 to $30 per user per month for standard plans. Zoom Phone starts at $10 per user per month, FreJun at $14.49, Grasshopper at $14 flat for the whole account, and RingCentral at $30 per user per month. For a team of 5 reps, you’re looking at $50 to $150 per month total, which is significantly less than a traditional phone system with hardware and maintenance costs. Most platforms offer free trials so you can test before committing.
You’ve now seen exactly how the top VoIP number software platforms compare on price, features, and fit. The gap between evaluating and actually improving your team’s call performance is usually just one conversation. Most teams that book a FreJun demo are live and calling within a week.
