The voice communications industry is a fascinating environment to work in, but many businesses find themselves struggling to modernize due to a language barrier of sorts, namely due to terminology that can get really technical. Today, let’s explore some more popular telecom terms and define them to help paint a clearer picture.


Otherwise known as Dynamic Host Configuration Protocol, DCHP is a protocol incorporated to ensure fast, automated centralized management of IP address distribution on a network. It can, therefore, be used to streamline voice communications efficiency such as with a cloud-based VoIP solution.


This is a practice in which customers are billed for enhanced features that they did not request, including voicemail, caller ID and call-waiting. Solutions such as DirectNet offer transparent pricing and no-nonsense custom options to ensure this is avoided.

Personal Communications Service (PCS)

A PCS represents any combination of wireless, voice and/or data communications systems sold as a service, incorporating digital technology for improved efficiency. A PCS can also be utilized to deliver other wireless solutions such as remote communications and wireless networking.  


Roaming pertains to the use of a wireless phone outside of the service area as defined by a service provider as your “home network.” When this occurs, rates can climb, and usually, you will incur per minute charges unless a travel data feature is applied to your bill in advance for the duration of your travels.


This is a term used for the unauthorized switching of long-distance services between companies without customer permission. Doing so directly violates customer protection rules such as those implemented by the FCC.

Universal Service

This is a financial mechanism that helps compensate phone companies and other communications-based entities for providing access to their services at respectable rates. It factors in coverage pertaining to rural, insular and high-cost areas as well as to public institutions.


Bandwidth refers to a telecom line’s signal-carrying capacity. Higher numbers represent stronger network stability and faster speeds. The bandwidth is calculated by analyzing the spectrum required to transmit data without distorting or corrupting it. Suppression of bandwidth signals that exceed standardized bands protects against interference.

From slamming to cramming, unified communications to unified messaging, we’ve gone over quite a few key telecom terms over the past few months. Hopefully, some of these definitions have proved useful in developing a deeper understanding of what cloud-based VoIP solutions can achieve for your business.
