What is a VoIP Phone System?
Voice over Internet Protocol (VoIP) makes it easier for companies to handle calls over the internet than traditional landlines. With a VoIP phone system, companies can easily manage calls on any smartphone, computer, and desk phone.
Common components of business VoIP include softphone apps, physical desk phones, and an auto-attendant. Business phone systems offer advanced functions, such as:
- Call Routing: Automatically direct incoming calls based on criteria like phone number, agent capabilities, or the time of day.
- Call Analytics: Measure real-time phone call volume for VoIP calls, auto attendants, or locations.
- Call Recording: Silently record any phone call made through your telephone system without any adapters.
- Voicemail Transcription: When you can’t answer an incoming call, get an email or text message with an accurate voicemail transcript.
- Business Text Messaging: Exchange SMS text messages with customers and team members from your desktop or mobile app — perfect for a quick check-in.
- Video Conferencing: Host video meetings with your team, including chat and business conference calls for clients.
- Admin Management: Add employees to your VoIP phone system and streamline your handset setup with pre-configured VoIP desk phones.
Small business VoIP phone systems are surprisingly affordable. Why? Advanced features use digital signals instead of the analog public-switched telephone network (PSTN). Pricing for Nextiva’s VoIP phone system is straightforward and offers the best value for small businesses.

Traditional vs. VoIP Phone Systems
Does your business phone system
belong in the past?
Desktop & mobile apps
The Nextiva desktop app, Android, and iOS app, streamline business communications over any internet connection. Voice, chat, and team messaging in one mobile app.
Can your analog phone system do that?
HD call quality
Get crystal-clear phone call quality, so your voice is heard clearly the first time, even over Wi-Fi. HD Voice technology is included with your VoIP phone system.
Traditional phone systems are prone to interference, making calls sound fuzzy or muffled.
Text messaging
Exchange text messages texts from your mobile phone or office phone system. Send and receive unlimited texts from any of your business phone numbers with Nextiva.
Traditional phone system landlines can’t get SMS messages without costly add-ons.
Call queues
Accept more incoming calls than agents available. Inbound callers can wait on hold, request a callback, reach a voicemail, or forward to an answering service.
Landline phone systems need complicated on-premises PBX hardware for call center functionality.
Customization
Every company has unique business needs that extend to your cloud-based phone system. Tailor each feature around the way you work, wherever your team works.
Analog-based phone lines are limited to where they’re installed, making them cost-prohibitive to scale.
Call flows
The bedrock of a modern VoIP phone system is how it handles incoming calls. Nextiva makes building call flows effortless for anyone.
Traditional phones lack smart call routing without IP PBX hardware and technical configuration.

Common questions about VoIP phone systems
Can I use VoIP with existing phones?
Yes, you can use VoIP with existing analog phones, but you’ll need an adapter known as an ATA. Generally, upgrading to IP phones is best for optimal reliability and call quality. VoIP phone pricing from Nextiva is as low as $90, and manufacturer rebates may still apply.
Can I transfer my phone numbers?
Yes, you can transfer your business phone numbers, also known as porting. In addition, you can choose which numbers you want to reserve for your company during your initial phone system setup.
VoIP works with any phone number you own, including local, cell, and toll-free numbers. We’ll even provide you with a temporary number with your caller ID as you transition.
How much does a VoIP phone system cost?
With all the vast capabilities of a cloud-based VoIP provider, you might feel it’s too expensive. Business VoIP from Nextiva costs $18.95–$32.95 per user monthly. You get unlimited calling minutes and won’t be locked into an internet service agreement.
Additionally, Nextiva provides volume discounts for larger organizations, so be sure to ask your sales representative. Also, you’ll save up to 90% on international calls compared to PSTN traditional phone systems.
How many different phone systems are there?
There are four types of VoIP phone systems to consider for your business:
- Cloud-based VoIP phone system (Unified Communications)

With a phone system hosted in the cloud, you never have to worry about technical setup, costly routers, or ever outgrowing it. With VoIP, there’s limitless customization available — from the apps to the hardware to the customer experience.
Whether you work from Microsoft Outlook or Salesforce CRM, you can place voice calls on your terms with cloud VoIP technology. Nextiva provides a full-featured VoIP phone system alongside its productivity software, call center, and SIP trunking products.
