Interactive Voice Response or IVR is an automated telephony system that interacts with human callers through the use of voice and touch-tone keypad selections (DTMF tones). It’s also commonly known as a phone tree.
Jitter is the variation in periodicity of a signal or periodic event from its target or true frequency. In telecommunications, jitter further refers to the variation in latency of packets carrying voice or video data over a communications channel.
Latency is the time delay between the initiation of an event and its perception by some observer. In networking and telecommunications, latency is the time between a sender causing a change in a system's state and its reception by an observer. Network latency is often informally used interchangeably with lag.
Live chat is a type of online chat distinguished by its simplicity and user accessibility. Live chat appears in a web browser or in mobile applications, usually via a small pop-up modal through which the visitor can exchange text messages with a chat operator in real time.

Machine learning is an application of artificial intelligence that enables computer programs to learn and improve automatically as they are exposed to new data, without being explicitly programmed.
Masked calling is a technique used in ecommerce to protect buyers' and sellers' personal phone numbers private. It uses a short-lived phone number for each party, allowing them to communicate seamlessly during a specified time period. After the time period has expired, the numbers are recycled and reassigned to other parties on the platform, which helps keep transactions from happening outside the platform.
Masked Phone Numbers are a common pattern to anonymize communication between multiple parties and hide participant phone numbers. Instead of dialing directly from phone to phone, users communicate via a third ('proxy') phone number that forwards a call to the eventual destination.
A Mean Opinion Score (MOS) is a numerical measure of the human-judged overall quality of an event or experience. In telecommunications, a Mean Opinion Score is a ranking of the quality of voice and video sessions.
Most often judged on a scale of 1 (bad) to 5 (excellent), Mean Opinion Scores are the average of a number of other human-scored individual parameters. Although originally Mean Opinion Scores were derived from surveys of expert observers, today a MOS is often produced by an Objective Measurement Method approximating a human ranking.
In a multichannel contact center, companies connect with customers via multiple communications channels – such as email, social media, web chat, and voice. However, just because customers connect via multiple channels does not mean that their experience is seamless.
Natural language processing (NLP) helps computers understand and interpret human language by breaking down the elemental pieces of speech.
Net promoter score, often referred to as NPS, is an important metric that measures how likely customers are to recommend a business. The idea behind NPS is companies who are recommended by their customers are more likely to grow.

North American Area Codes are prefixed to a phone number to assist in routing phone calls in North America. The North American Numbering Plan (NANP) dictates the regional and non-geographic area codes assigned to signatory countries. The United States, Canada, some Caribbean countries, and all US territories are covered by the plan.
In an omnichannel contact center, all communication channels (such as phone, SMS, online chat, and email) are connected and integrated to provide a seamless customer experience. Omnichannel contact centers let agents switch between channels from one user interface, without losing context from customer interactions across all other channels.
An on-premise contact center is a contact center model where all software and hardware required to maintain and operate a call center is located on a customer’s property. Companies using an on-premise system generally employ or contract with specialized IT staff responsible for configuration, upgrades, and upkeep of the contact center.
Order notifications give businesses the ability to inform customers of the status of their order, which could include confirmations, pricing adjustments, delays in fulfillment, or delivery scheduling.
P2P stands for Person-to-Person messaging. In simple terms, this is when two or more people communicate over text messaging. For example, when you send a text message from your phone to another person's phone, that's P2P. This can also include traffic that goes through an API to connect two people.
Packet loss refers to the failure of packets to reach their destination on a network. Packet loss is most often a consequence of network congestion and usually caused by network equipment dropping, ignoring, misdelivering, or discarding packets.

A SIP trunk is a virtual version of an analog phone line, eliminating the physical connection to a phone company. Using SIP trunks, a SIP provider can connect multiple channels to your PBX, allowing you to instantly provision global voice connectivity for your Voice over IP (VoIP) infrastructure.
SMS stands for Short Message Service and is another name for a text message. An SMS is generally sent from one mobile device to another over the cellular network. SMS is a text-only standard first formalized in 1985 in the Global System for Mobile Communications (GSM) standards.
As the infrastructures for SMS communications and the internet are mostly divided, SMS APIs are often used to 'bridge the gap' between telecommunications carrier networks and the wider web. SMS APIs are used to allow web applications to easily send and receive text messages through logic written for standard web frameworks.
The character limit for a single SMS message is 160 characters, however most modern phones and networks support concatenation and segment and rebuild messages up to 1600 characters. Messages not using GSM-7 encoding are limited to 67 characters.
SMS Delivery is a measure of the percentage of outgoing SMS and MMS messages which are received at their intended destination. While sometimes referring to the status of a single message, SMS delivery usually is a rate of delivered versus intended messages and summarized as an 'SMS Delivery Rate.'
An SMS Gateway enables a computer to send and receive SMS text messages to and from a SMS capable device over the global telecomunications network (normally to a mobile phone). The SMS Gateway translates the message sent, and makes it compatible for delivery over the network to be able to reach the recipient.
SMS Notifications are out-of-band text messages sent in response to events or transactions which occur somewhere else. While often used as a marketing tool to increase the percentage of returning visitors, SMS notifications are very useful for organization and public safety purposes as well.
An SMS tracker is software that uncovers detailed information about the delivery and content of text and picture messages. It allows anyone to analyze an individual message or group of messages to see delivery patterns, encoding details, and error conditions.
Sticky Sender is a valuable feature for SMS or Voice marketing where all outbound customer contact comes from a single number. This 'sticky' or 'unchanging' number increases customer familiarity and trust. With a two-way Voice or SMS system, it also allows customers to contact businesses and organizations through the very same number.
A String Identifier (SID) is a unique key that is used to identify specific resources.

TOTP stands for Time-based One-time Passwords and is a common form of Two-factor Authentication. Unique numeric passwords are generated with an algorithm that uses the current time as an input. The time-based passwords expire and therefore offer increased security for 2FA. TOTP is also known as a soft token.
TwiML, or the Twilio Markup Language, is an XML based language which instructs Twilio on how to handle various events such as incoming and outgoing calls, SMS messages and MMS messages. When building a Twilio application you will use TwiML when communicating your desired actions to Twilio.
UCS-2 is a character encoding standard in which characters are represented by a fixed-length 16 bits (2 bytes). It is used as a fallback on many GSM networks when a message cannot be encoded using GSM-7 or when a language requires more than 128 characters to be rendered.
Unicode is an international character encoding standard that provides a unique number for every character across languages and scripts, making almost all characters accessible across platforms, programs, and devices.
UTF-8 is a variable-width character encoding standard that uses between one and four eight-bit bytes to represent all valid Unicode code points.
A virtual phone number is a standard telephone number that is not locked down to a specific phone. A virtual number can route a voice call or text message to any phone or workflow. With virtual numbers powered by an API, complex software workflows can be built that are triggered by calls and texts.
Virtual SMS enables you to send and recieve SMS text messages over the internet without having to use a physical phone. This is especially useful when you want to use software to communicate with telephone networks that would be impossible on a physical phone, e.g. Uber notifying a customer that their car is outside or to have local phone numbers in different countries.
A voice API is a tool for software developers to make and receive phone calls with a simple, easy to understand API. Behind the scenes, a voice API bridges the Public Switched Telephone Network (PSTN) and applications connected to the internet. By using a voice API, software developers can program voice calling into their applications without specialized telecommunications knowledge and hardware.
It is especially useful for scenarios where you want to track or control the transaction between two users, for example in a marketplace. Examples of peer-to-peer marketplaces that use Twilio as a Voice Proxy are Uber, Lyft, Airbnb, Postmates and Instacart.
There are two main options to build a Voice Proxy solution:
Voice trace is a voice quality troubleshooting feature that captures the media stream for calls and stores them for Twilio Support to use in their investigations.
