Integrated Services Digital Network (ISDN) is a circuit used for digital transmissions of voice, data and other network services. They are utilised over the Public Switched Telephone Network (PSTN). The common circuits are ISDN2 and ISDN30. In 2015, BT announced that they would be phasing out ISDN solutions and switching the network off entirely. This means existing ISDN capacity is being ceased and new orders will be not be accepted. Come 2025, the whole ISDN copper network and all associated solutions will no longer be supported.

Intelligent Cloud Queuing (ICQ) is a call queueing software that automatically answers the call and then holds callers in order until a handler is available to answer. Features can include callers hearing their position in the queue or informative messages as well as the facility to request a call-back once they are at the front of the line.

Interactive Voice Response (IVR) is the ability for a computer or digital setup to interact with individuals e.g. inbound callers may transition through a telephone system to meet an appropriate destination. This may be a mix of voice and Dual-Tone Multi-Frequency (DTMF) inputs.

International Mobile Equipment Identity (IMEI) is a unique identity number assigned to a GSM device that can be recognised and blocked by the network to which it is connected. It is useful for fraud prevention and to bar access using a stolen phone. 

Internet of Things (IOT): refers to the billions of devices worldwide that are connected to the internet to receive and transmit data. IOT SIM cards can be supplied for GSM (Global System for Mobile communications – the internationally used standard platform for mobile phones) units if required for lift/alarm lines and other analogue services.
