IAD
incoming call queuing

inductance coupling
It is a transformer model implementing coupling through a space high frequency alternating magnetic field, which is based on the law of electromagnetic induction.
Instant conference
When no conference is reserved, the host can hold an instant conference by calling other subscribers.
Integrated Access Device
An Integrated Access Device is an access node that can simultaneously deliver Class 5 switch voice services, packet voice services, and data services (via LAN ports) over a single WAN link. IADs provide a common platform that enables service providers to deliver voice and data over a single access network reducing the cost of co-located equipment in the Telco central office and allowing service providers to least fewer transport spans.
Integrated Services Digital Network
A network defined in CCITT, providing comprehensive transmission service for the voice, video, and data. The ISDN enables the voice, video, and data transmission on a small number of data channels simultaneously, thus implementing a comprehensive transmission service.
intelligent routing
It is a routing mode in which a call is forwarded to a predefined address due to the registration of a forwarding service (such as call forwarding unconditional, call forwarding busy, call forwarding unreachable, or call forwarding no reply).
Interactive Voice Response
A telecommunications system which uses a prerecorded database of voice messages to present options to a user, typically over telephone lines. User input is retrieved via DTMF tone key presses.
internal call recording
The IVR recording flow helps record a call between internal subscribers, a call when an internal subscriber calls a PSTN subscriber, and a call when a PSTN subscriber directly calls an internal subscriber. With internal call recording, the calls of internal subscribers are monitored.
intra-office prefix
The identical preceding one or multiple digits of the extensions in an office.
IP Contact Center
