There’s a wealth of information for buyers looking at business IP phone systems, and it can get confusing to understand the different options available. To start learning more about the basics of IP phones, business IP phone systems, and VoIP, read through this helpful article.

What is an IP Phone?

IP phones, also known as VoIP phones, look similar in appearance to traditional desk phones but are far more advanced. Like small computers, all the on-board features are applications, and the user can customize the display and buttons.

IP phones are wired using Ethernet cables and connect to an IP-based phone system. In contrast, traditional desk phones use an analog cable and typically connect to analog or legacy digital phone systems. IP phones are powerful because they use an Internet protocol called SIP (Session Initiation Protocol) to send and receive audio.

How to Switch to VoIP

  1. Prepare your network infrastructure: Unified Communications (UC) solutions can be utilized with Voice over Internet Protocol (VoIP) systems and bring many benefits to businesses, including reduced IT costs and the ability to integrate business processes such as chat, presence, screen, and video sharing, CRM and support functions, and more. However, the role of networking is crucial during migration to VoIP/UC.

  1. Test if your internet connection is strong enough for VoIP: If you’re considering a VoIP phone system for your business or organization, you’re probably well aware of the many benefits a VoIP phone system has to offer. Bandwidth is a series of essential aspects of your VoIP phone system setup that is critical for success. To help you determine how much bandwidth you will need to support a new phone system, users can use the following equation:
  • G711 – A standard VoIP call protocol requires approximately 64kbps.
  • Using G711, you can have approximately 12 concurrent calls for each 1Mbps of bandwidth.
  • So, if your company needs to support 120 concurrent calls, you’d need a 10Mbp service.

  1. Find the right VoIP provider: Now that you understand what VoIP is, the next step is to figure out your business requirements. To do that, however, you will have to start by identifying your organization’s business communications needs.

Once you have identified your operational needs, you can start to look for VoIP providers that can meet your requirements. There are different types of VoIP providers in the marketplace that generally fall under three categories: VoIP-only providers, VoIP with cloud phone system providers, and VoIP as part of unified communications solution providers. The third option addresses the most common business communications needs while improving efficiency by combining solutions in one platform.

“Sangoma’s UC platforms can be augmented with a range of hardware and accessories designed to provide the tightest possible integration with our phone system software. Customers no longer have to purchase software, system appliances, phones, and other hardware from separate sources. With Sangoma, customers can expect a complete custom solution, all from one vendor.”

  1. Know the key features your VoIP provider is offering: Even if a VoIP provider meets all your business communications requirements, you must ensure the provider’s reliability and security features. Securing a network is never a trivial task and requires ongoing attention as threats evolve.

It is essential to understand the protection features of a business phone system. Toll fraud is a costly lesson to learn and can cost businesses a lot of money over a short period. 

A sound business phone system should:

  • Limit the amount of call traffic a hacker can create
  • Lockdown extensions from specific IP addresses or subnet ranges
  • Change the default port for SIP.
