Behind the Jargon: A VoIP Dictionary

Navigating the world of VoIP can sometimes feel like learning a new language. Here’s a quick glossary of some common VoIP terms to get you started:

Auto Attendant

Think of this as your digital receptionist. It greets callers and directs them to the right department, agent, or group of agents through an automated menu system. This reduces the need for a live operator, speeding up the customer service process.


Short for Direct Inward Dialing. DID allows you to assign individual phone numbers to employees without requiring a physical phone line for each. This makes it easier for outside callers to reach a specific person or department directly, reducing wait times.


This abbreviation stands for Interactive Voice Response. Ever called a business and been asked to “press 1 for sales, 2 for support”? That’s IVR. With it, you can create multi-level menus to guide callers through different options, ensuring they’re directed to the right department, agent, or group of agents.

Number Porting

It’s a process that allows users to retain their existing phone numbers when switching service providers. This way, you can ensure seamless continuity of how your customers can reach your business.

Packet Loss

With VoIP, conversations are split into tiny “packets” of data. Packet loss happens when some of these don’t reach their destination. Such packet loss can result in poor call quality, including stuttering, interruption, or dropped calls.


Short for Private Branch Exchange. This is a private phone network within your company. It lets your employees call each other on internal lines, saving on costs. Users of the PBX phone system can communicate within their company and with the outside world using different communication channels like Voice over IP, ISDN, or analog.


Public Switched Telephone Network is the traditional telephone network that uses copper wires to carry analog voice data. It’s the standard phone system that has been used around the world for over a century and is also known as the landline telephone system. VoIP is a modern, flexible alternative to PSTN.


That is, Session Initiation Protocol. It’s a signaling protocol used for initiating, maintaining, modifying, and terminating real-time sessions that include voice, video, and messaging applications. It’s a key component of IP telephony.

SIP Trunking

It’s a method of sending voice and other unified communications services over the internet. It replaces traditional phone lines and allows for simultaneous call management, providing significant cost savings and operational flexibility.


(Session Initiation Protocol Application Layer Gateway): This is a feature in many routers that helps SIP traffic get through your network’s firewall. However, it can sometimes interfere with the proper functioning of SIP traffic, and so it’s often recommended to be disabled in settings where VoIP services are being used.


From your old landline phones to modern VoIP systems, this is the general term for all technology involved in transmitting voice communication.

Toll-Free Number

 A phone number that can be called with no or minimal cost to the caller. Instead of the caller, the entity that owns the toll-free number (you) bears the calling costs. Toll-free numbers can be used for both inbound and outbound calls.
