Enterprise business phone service for today’s organizations

Cloud-based systems are an excellent choice for enterprise business phone service because they use Voice Over Internet Protocol (VoIP) technology. VoIP allows you to make and receive calls over the internet, rather than through traditional phone providers.


In the last decade, millions of businesses have made the switch to VoIP because of the numerous benefits such technology provides. Enterprise VoIP solutions deliver integrated communications for the modern business world. Business VoIP systems are generally more affordable, easier to set up, and more flexible. But the main reason why companies switch to a business VoIP solution is to take advantage of the many advanced features these systems provide to a modern global enterprise.


Here are things to know about choosing the best business phone service for your organization.

The benefits of cloud VoIP phones for enterprises

Hosted cloud VoIP systems are more affordable to deploy than on-premises solutions, which often have extensive hardware costs and installation requirements. Because hosted cloud phones are maintained and managed by your VoIP provider, you don’t need a dedicated IT department with specialized knowledge and expertise.


Considering switching your enterprise business phone service? Here are a few reasons to choose a cloud phone system over a traditional, on-premises PBX system:

  • Affordable plans at predictable rates

  • Reduced equipment costs and contracts

  • Fast, easy phone system deployment

  • Comprehensive business phone features like call recording, caller ID, call routing, and more

  • Integration with third-party software

  • Simple to scale and provision new users

  • Port existing business phone number(s) over

  • Make calls from any device

  • No IT expertise needed

  • Make and receive calls using your existing internet connection

Additionally, moving your phone system to the cloud as part of a comprehensive UCaaS solution can provide additional enterprise business benefits. Unified communications enable you and your team to connect via phone, video conferencing, or chat on one streamlined platform so you can collaborate and communicate with customers via their preferred channel.

Why cloud VoIP phones are superior to traditional landline phones

Not only can a cloud phone system compete with traditional phone technology, it’s often better since it was developed for business in the age of the internet. Additionally, VoIP business phone systems come pre-stocked with additional unified communications tools (think video conferencing, chat, and SMS), modern features (caller ID, call recording, and more), and also integrate with your core enterprise applications, improving productivity.


Here are a few reasons why business VoIP phones are superior to traditional landline options for your enterprise business phone service:


VoIP Landlines
HD voice quality Standard voice quality
Conduct calls from almost any device Calling limited to traditional desktop phones
Low, predictable pricing Higher costs, particularly for advanced systems

Transitioning from legacy PBX to an enterprise phone system is a multistep process. Our onboarding team can help make the transition easier, but here is an overview of the process that most firms will follow:


  1. Inventory & assess – Start by taking an inventory of existing hardware, existing business phone lines, number of employees, business locations, etc. You will also want to assess current bandwidth availability, and estimate how the transition to VoIP will affect connectivity speeds and bandwidth usage. It’s helpful to have a clear idea of what the current network looks like, and what needs the firm will have when transitioning to enterprise VoIP.
  2. Collaborate & estimate – On the enterprise level, a transition to a VoIP business line will likely require collaboration between several departments in the firm. To make the transition as smooth as possible, fully evaluate LAN or WAN reliability, bandwidth availability, network performance, and any other relevant factors, before migrating to enterprise VoIP.
  3. Contact sales – Once a firm’s current telephony network has been inventoried and assessed, it’s time to contact Zoom Phone Sales to purchase your business lines. For enterprise clients, we recommend contacting sales directly for help putting together a personalized transition plan for their business phone system.
  4. Port numbers – Next, the firm will need to begin the porting process to migrate existing phone numbers to the new VoIP provider. Zoom Phone Professional Services can help with this process, but typically the firm will need to contact their existing provider to begin porting their business lines.
  5. Procure hardware – In many cases, the next step will be to procure IP-enabled telephone hardware for your business phone system. Depending on the desired setup, this could include new desktop office phones, conference phones, or simple headsets for VoIP calls over office computers. For lower upfront costs, firms may consider utilizing Zoom Phone Hardware as a Service.
  6. Configure & customize – Working together with in-house IT and Zoom Phone’s support team, firms can move on to configure and customize their new business VoIP system. This includes configuring physical hardware and network components, as well as customizing virtual features of Zoom Phone.
  7. Schedule cutover – Once the new system is configured properly, you can schedule a cutover day for the full transition to business VoIP. Depending on the size of your organization and network requirements, this may take place immediately, or in a multi-phase process.
