Business phone systems are multi-line telephone services that allow business employees to communicate both internally and externally. Typically, these systems are meant for businesses that handle a large volume of calls, and thus may require integration between multiple types of devices to assist in managing the load.

Business phone systems are for any size business that wants the functionality and features of a centralized and integrated phone system as opposed to dealing with individual lines provided by the phone company, which could be costly.

When selecting a business phone system, take care to consider the specific array of features that can be tailored to a given business’s needs. These can include maximum user numbers, custom hold music, conference calling, smart phone integration, and voicemail-to-email to name a few. If choosing VoIP, take into consideration if you want to host the system on-premises or have it hosted by the service provider.

When purchasing a business phone system, first verify a given company’s time in business to ensure it is historically reliable. If reported up-time is less than 99.9%, then another company should be considered. Furthermore, in the case of an outage, make certain that the systems are in place to handle such an event. 24-hour phone support, for instance, is a must. By addressing these questions first, there’s less likely to be disappointment later.

How We Compare Business Phone Systems

This is the core of the business phone service. Major players feature a huge variety of phone, web-based, mobile, and cloud applications and integrations. We initially look at the options for phone set up. This incudes whether or not the company allow you to set up toll-free numbers for your customers to call, if they allow for vanity numbers like 1-800-FLOWERS, and if they allow you to set up international numbers that are forwarded domestically enabling those outside the country to call without incurring international rates. We'll also consider the myriad calling features a company offers. This includes variations of phone, video, SMS, mobile, and fax options. Administrative controls refers to the system's ability to record call logs and conversations. Finally, we'll also look at whether the provider offers live receptionists as a service.

  • Auto Attendant: Allows callers to be automatically transferred to an extension without the intervention of an operator
  • Interactive Voice Response: Allows customers to interact with a company’s host system via a telephone keypad or by speech recognition to complete certain tasks

Systems

30%

Systems refer to the global characteristics relevant to a given company's business phone package. This typically includes the type of connection: Voice Over Internet Protocol (VoIP) uses hardware and software to enable the businesses' employees to talk with each other and the outside world using the internet as the transition medium, Analog uses traditional landlines and is far less prevalent these days. It also includes how the VoIP Public Branch Exchange (PBX) is hosted. Some VoIP services are hosted with the switching equipment on premises in a configuration known as SIP Trunking. This is a process that leverages a company’s existing on-premise PBX but then connects to internet lines rather than traditional landlines. The other, far more popular method of VoIP hosting is cloud-based. Finally, sometimes providers offer a Uptime Percentage Guarantee. Expressed as a percentage, this is often a company guarantees that you can expect the system to be functioning and not out due to internet failure. The industry standard is 99.99%.

Customer Questions & Answers

What is VoIP?

Voice over Internet Protocol (also called Voice over IP, VoIP and IP telephony), is a group of technologies that deliver voice communications and multimedia over your internet connection. Essentially, it uses your high-speed internet connection for your phone service instead of a landline.

What is a PBX?

A Private Branch Exchange (PBX) is a company’s multi-line telephone system for internal and external calls. Traditionally, this would be done either via a system lock-in or a vendor lock-in, but has moved towards delivering phone calls through Internet Protocol. This cancels out the need for constraining the amount of outside telephone lines and internal devices or extensions, resulting in a virtually limitless system.

What is SIP Trunking?

An SIP trunk is a direct connection between a company and an internet telephony service provider. This configuration is easier to maintain and provides services, notably long-distance, at substantial savings over traditional telephony. SIP trunks can also carry instant messages, multimedia conferences, user presence information, Enhanced 9-1-1 (E9-1-1) emergency calls, and other real-time communications services.

What is CTI?

Computer Telephony Integration (CTI) is a common name for a technology that permits computer systems to interact with telephones and other forms of communication, such as email, text messaging, web messaging, live chat, and fax. With CTI, actual telephones are unnecessary, as users make and receive calls directly from their computers.
