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.

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.

What is IVR?

Interactive Voice Response (IVR) is a telephony menu system that automates a company’s customer support through the identification, segmentation, and routing of callers. It allows the company to make pre-recorded or customized messages, prompts, and messages, as well as prioritize calls based on value.

What is auto attendant?

Auto-attendant (AA) is a voice menu system that transfers callers without going through a telephone operator or receptionist. It usually provides a dial-by-name directory for callers to find a user on the phone system, as well as a simple menu system. AA can also route calls to mobile phones, VoIP virtual telephones, and land-lines.
