What is a VoIP Phone System?

To meet the demands of modern businesses, it’s crucial to have a reliable and advanced communication system. If you’re unsure where to begin, consider implementing a Voice over Internet Protocol (VoIP) phone system, also known as IP Telephony.

VoIP enables voice communication over the internet instead of traditional phone lines. It operates by transmitting digital voice data packets over an IP network like the internet or a local area network (LAN).

So, how does VoIP work? This internet-based system converts voice calls into digital data and transmits them via the network. Compared to conventional telephone systems, VoIP offers cost-effectiveness, efficiency, and a range of features such as call routing, voicemail, call forwarding, conference calling, and integration with 3-party applications.

VoIP solutions can be deployed in various ways, including on-premises setups, hosted/cloud-based services, or hybrid configurations. These options provide flexibility, scalability, and cost savings, making VoIP systems highly popular for businesses of all sizes.

It's Time to Take a Leap to VOIP

In the long run, IP telephony surpasses traditional analog ones in terms of functionality, flexibility, cost, and reliability. That's why businesses today are switching from landline phones to Internet-based phone system. If you're considering upgrading to VoIP or still doubt about the differences between a traditional phone system and VoIP, take a look at this straightforward table:

4 Tips for Painless VoIP Migration

Tip #1: Develop a Migration Plan Ahead

It’s important to develop a comprehensive plan that outlines how quickly you want to make the switch and what approach you prefer.

You can choose between a complete replacement using an All-IP approach or a phased transition where both the traditional phone service and VoIP work together.

Additionally, consider factors such as your budget, company size, and specific operational needs to decide whether to deploy the VoIP phone system on-premises or in the cloud. And ensure you have enough phone lines and handsets to support all employees on the new system.

Tip #2: Make Sure Your Network is Ready for VoIP

It is a no-brainer that IP telephony heavily relies on network.

So confirm that your network has the necessary stability and sufficient bandwidth to support VoIP effectively. Maintaining a stable network is vital for preserving high-quality VoIP calls. Factors such as latency, packet loss, and jitter can significantly affect call quality.

To guarantee a seamless VoIP experience, conduct thorough network assessments and make any required upgrades or optimizations based on the results.

Tip #3: Get the Right Phone Equipment for Your Business

VoIP technology offers a wide range of options for phone equipment and features. From call waiting to call forwarding and voicemail, these features can greatly benefit productivity.

However, it’s important to have compatible phones that can support these capabilities. To ensure a smooth VoIP experience, consult your VoIP service provider for a list of phones and peripheral devices that are compatible and user-friendly. Select phones that offer both compatibility and ease of use to make the most out of your VoIP system.

Tip #4: Maintain an Emergency Phone Plan to Avoid VoIP Issues

Since VoIP relies on internet connectivity, unplanned internet interruptions can potentially impact voice services, making it difficult for employees to effectively communicate with customers, suppliers, partners, and their teams.

Having an emergency phone plan in place or providing alternative network services can be helpful. Consider implementing redundant internet connections or having backup communication methods available to minimize internet disruptions and ensure business continuity during unexpected outages.

Common FAQs About VoIP Phone System

How does VoIP phone system work?


A VoIP (Voice over Internet Protocol) phone system works by converting analog voice signals into digital data packets and transmitting them over IP networks.

When you speak into a VoIP phone or device, your voice is captured and converted into digital data using a codec. This data is divided into packets, sent over the IP network, and then reassembled and converted back into analog signals at the recipient’s VoIP phone or device, allowing them to hear the communication.


Can I keep my existing number with VoIP?


The short answer is yes, you can bring your existing number over with you to Yeastar VoIP phone system. This process is known as number porting or number transfer, and it is super easy to complete. For specific instructions and assistance with the number porting, please contact us.


Is VoIP suitable for small business?


IP telephony is especially fit small and medium-sized businesses. This is because top VoIP companies typically charge per user, per month instead of based on total minutes used. This, along with not having to buy expensive equipment or hire dedicated IT staff, saves you money.

Plus, monthly plans with predictable costs make budgeting easier. You get all the communication tools you need for customers and teams in one service without surprise charges on your bill.

Are VoIP phone systems reliable?


Yes, VoIP phone systems can be reliable when implemented and maintained properly. However, reliability can vary depending on various factors such as the quality of your internet connection, network infrastructure, and the service provider you choose.

To ensure reliability:

  • Internet Connection: A stable and high-speed internet connection is crucial for reliable VoIP service. It’s important to have sufficient bandwidth to handle your call volume and minimize latency or packet loss.
  • Network Infrastructure: A well-configured and properly maintained network infrastructure is essential for ensuring reliable VoIP communication. This includes routers, switches, firewalls, and other network components that support VoIP traffic.
  • Service Provider: Choosing a reputable VoIP service provider with a strong track record in delivering reliable service is crucial. Look for providers that offer robust infrastructure, redundant systems, and good customer support.
  • Quality of Service (QoS): Implementing Quality of Service protocols on your network can prioritize and ensure consistent, high-quality voice traffic over other types of data traffic, enhancing reliability.
  • Redundancy and Backup: Having backup power supplies, redundant internet connections, and alternative communication methods available can help maintain service continuity during outages or disruptions.


What should I consider when choosing a VoIP provider?


  • Do you want to keep existing equipment? Does it support your needs?
    If you are using the traditional PBX and with a limited budget for a complete replacement of the existing equipment, make sure you select a VoIP solution that allows you to take a phased transition. Whether the new VoIP phone system is compatible with your traditional phone system, how to connect them together, how to ensure that the upgrade does not affect business continuity, etc. It’s also important to verify that the VoIP service providers you are considering will support that equipment. This is a stage where direct communication with the VoIP provider is key.
  • What kind of UC capabilities does this VoIP phone system offer?
    IP phone system offers more than just audio calls, so consider the unified communications (UC) features available. UC consolidates various communication channels into one access point. Look for UC features such as unified messaging, instant messaging, presence indicators, corporate directories, video conferencing, and team collaboration tools.
  • Is the IP phone system possible to integrate into other platforms and tools?
    As businesses rely on multiple platforms and tools, the ability of a IP phone system to integrate seamlessly becomes crucial. Look for a VoIP service provider that offers integration with other business-enhancing tools. This integration enables improved efficiency, communication, collaboration, and workflow streamlining.

By considering these factors, you can better evaluate VoIP options and find a solution that meets your specific needs, supports your existing equipment, provides comprehensive unified communications capabilities, and integrates with other essential platforms and tools.
