Posted on: September 28, 2017

Voice Over Internet Protocol is a field of ever-growing and upgrading technology. Every few months, new features, accessories uses and benefits are created for resellers, wholesale agents and end user customers. V1 VoIP wants you to stay up to date with the latest in the VoIP industry. Here is our list of some of the most currently common used VoIP terms used in voice communication.

If there is a term you need more information about or want to add to your portfolio of VoIP service offerings, contact a member of the V1 VoIP team. We are more than happy to answer your questions and more broadly define what these terms are and what they can do for your business.

ASR – stands for Answer / Seizure Ratio. It is the number of successfully answered calls divided by the number of attempted calls.

Asynchronous Communication – The transfer of data not synchronized by a clock signal; the process requires both a start- and end- bit to identify the packet’s source and destination.

ATA – stands for Analogue Telephone Adaptor. ATAs are hardware devices used to connect a PSTN telephone to the Internet. VoIP gateways and modems perform similar functions.

Bandwidth – The maximum amount of data that can be uploaded/downloaded over a single line over a fixed duration (i.e. bits per second). You’ll need this to operate VoIP.

Broadband – High speed internet via cable TV, DSL, or telecom.

Clipping – When sections of a conversation — the beginning or end of words — drop-off.

Codec – The compression-decompression process; it compacts data into a smaller format for lighter transmission, then unpacks it again at the destination.

Echo-Path Delay – The duration between a transmitted signal and its reflection.

Echo-Path Loss – The difference in signal strength between a transmitted signal and its reflection.

Frame mutes – The frequency of clipping during a conversation, expressed as a percentile.

Full Duplex – A form of communication in which both ends may send and receive data simultaneously.

Interactive Voice Response – commonly called an IVR, it’s a platform that translates a caller’s touch-tones and voice commands into computer information for access over the phone or vice versa. For example, a voice menu that requires a caller to punch in a pin or select an option.

IP – stands for Internet Protocol, which dictates how data packets are transmitted over the internet.

IP Address – An Internet Protocol Address is a unique identifier machines use to connect to the Internet. Both fixed and dynamic IP addresses exist, ranging from to IP mapping is the process of geographically locating a device based on its IP address.

Jitter – A temporary transmission flux caused by early or delayed data packets.

Latency – The delay between the initiation and transfer of data.

Packet – A group of datum containing both a destination and source. Packet loss occurs due to latency or switching overload, at which point the data never reaches its destination.

POTS stands for Plain Old Telephone Service, you know, those old school landlines. Traditional phone service over the Public Switched Telephone Network or PSTN.

Router – A network device that stores and forwards packets.

Sampling – A method used to measure and encode analogue signals into a digital format.

SIP – stands for Session Initiating Protocol, which is a standard for initiating, maintaining, and terminating interactive user sessions like video calling, instant messaging, or VoIP.
