Cloud PBX and Virtual Business Phone Providers

Compare Six Business Phone Providers

Phone service from a Cloud based PBX service.

Nextiva, RingCentral, Grasshopper, Quo, Talkroute, and UniTel Voice offer different approaches to business calling. This guide compares options for offices, remote employees, entrepreneurs and small teams.

Start with the way your business handles calls. An office replacing a PBX may need desk phones, extensions, call queues and centralized administration. A solo business owner may simply need a separate business number, professional greetings and calls delivered to an existing smartphone.

Provider information reviewed: . Prices and features can change.

These are not six identical services. Nextiva and RingCentral belong on the shortlist for office phone system requirements. Grasshopper, Quo, Talkroute and UniTel Voice offer alternatives for businesses focused on mobile calling, shared conversations or professional call routing.

Cloud Phone Systems for Offices and Growing Teams

Compare these providers when your requirements extend beyond a second business number to employee calling, office call handling and a broader communications platform.

Business phone and customer communications

Nextiva

Consider for: teams that want business calling, video, messaging and room to add customer communication tools.

  • Engage adds customer-to-team SMS, toll-free numbers and minutes, and advanced reporting.
  • Scale adds features such as skills-based routing, blended inbound and outbound calling, and AI summaries.
  • XBert AI Receptionist is offered as an add-on.

Unified business communications

RingCentral RingEX

Consider for: businesses comparing calling, meetings, messaging, app integrations and multi-site administration. On-premise Avaya/Mitel PBX cloud integrations.

RingEX is RingCentral's current business communications platform name. It brings calling and collaboration together across desktop and mobile applications, with support for compatible desk phones.

Features to compare

  • Business calling with unlimited external calls within the United States and Canada.
  • Auto-attendant, meetings and team messaging capabilities.
  • Integrations with business applications and CRM platforms.
  • Advanced and Ultra packages add administrative and analytics capabilities for more complex organizations.
  • Optional products include AI Receptionist and enhanced call queue and business texting tools.

Pricing: compare the current Core, Advanced and Ultra offers on RingCentral's website. Annual payment, selected package and add-ons affect the total cost. Use certified professionals for PBX integrations.

Check before choosing: confirm which integrations, analytics and call handling features are included in your quoted package. Do not assume every advertised AI or customer engagement feature is part of the base plan.

Virtual and App-Based Phone Services for Small Businesses

Compare these services when your priorities are a separate business number, professional call handling or customer conversations shared across a small team.

Entrepreneurs and mobile businesses

Grasshopper

Consider for: solo business owners and small teams that want a professional business number without building an office phone installation.

Grasshopper focuses on separating business communications from personal calls and making a small business easier to reach. Compare its current plans against the number of people, phone numbers and extensions you need.

What to compare

  • Business number and extension requirements.
  • How employees receive calls while working remotely.
  • Voicemail and business messaging requirements.
  • Monthly versus annual billing and current trial terms.

Pricing: view Grasshopper's current plan selector for True Solo, Solo Plus and Small Business pricing, included numbers and extensions.

Check before choosing: compare your required call handling and collaboration features with the selected plan. A mobile-focused virtual phone service should not automatically be treated as a replacement for every office PBX function.

Confirm any charges for additional numbers, messaging registration or usage beyond your plan's allowances.
