ANI

Automatic Number Identification

Identifies who is calling the recipient of the call. With Click‐to‐Call this feature is used to provide a more meaningful caller ID than an eStara‐specific caller number.

CORS

Cross Origin Resource Sharing defines ways for a web server to allow its resources to be accessed by a web page from a different domain.

Customer, Customer Account, or Account

This is an organization that has subscribed to one or more Live Help services such as Call or Chat. Such an organization will make use of one or more of our rules engines to present call and chat invites on their consumer‐facing websites.

E.164

E.164 is an ITU‐T recommendation that defines the international public telecommunication numbering plan used in the PSTN and some other data networks. It also defines the format of telephone numbers. E.164 numbers can have a maximum of fifteen digits and are usually written with a + prefix. To actually dial such numbers from a normal fixed line phone, the appropriate international call prefix must be used.

End User, Visitor, or Consumer

This represents the end user who visits the web site(s) of the customer account and optionally clicks on a call or chat invite when he or she requires assistance.

HTTP

Hypertext Transfer Protocol

Application protocol that is the foundation for data communication for the World Wide Web.

JSON

JavaScript Object Notation

A text‐based open standard for data interchange that is more lightweight than XML for serializing and transmitting data between a server and a web application.

JSONP

JSON with Padding

This is a complement to the base JSON data format.

It provides a way of requesting data from a server in a different domain, which is usually prohibited by web browsers because of the same origin policy. It can be used instead of CORS for web browsers that don’t support CORS.

Long Polling

A variation of the traditional polling technique that allows emulation of an information push from a server to a client. With long polling, the client requests information from the server in a similar way to a normal poll. However, if the server does not have any information available for the client, instead of sending an empty response, the server holds the request and waits for some information to be available. Once the information becomes available, or after a suitable timeout, a complete response is sent to the client.

REST

Representational State Transfer

This is a style of software architecture for distributed systems. It has emerged as a key web service design model that has increasingly displaced other design models such as SOAP and WSDL.

RESTful Web Service

A web service implemented using HTTP and the principles of REST.

SIP

Session Initiation Protocol

IP network protocol mainly used for VoIP (Voice Over IP) telephony.
