# CTI Support

## Description

IMPORTANT: MiTAI support is for legacy use only and is not permitted for new installations.

The Mitel Open Integration Gateway (Mitel OIG) is a web server that provides each Mitel OIG application a single point of access to web services available within a MiVoice Business communication system, including for call control and CTI applications. The Mitel OIG provides a service-oriented architecture. A Mitel OIG application opens a communication session with a Mitel OIG by logging in (that is, sending a service operation or request to the Mitel OIG). After the Mitel OIG application is authenticated and authorized, the application can use this one communication session to access all Mitel OIG web services the application is authorized to use on the MiVoice Business system.

The Mitel OIG allows applications to submit requests using web service operations. The Mitel OIG processes each request and provides a response. Some requests result in a state change in the Mitel communication system and the Mitel OIG then initiates an event for the application. The Mitel OIG supports the following web services:

- Session Management service – Open communication session with Mitel OIG for services.

- Call Control service – Control and monitor CTI behavior in a Mitel communication system.

- Data Access service – Register for MiVoice Business configuration data change notifications and read MiVoice Business configuration data.

Software developers are required to join the Mitel Solutions Alliance (MSA) developer partner program, at one of the Developer Advanced membership levels, in order to develop or modify Mitel OIG or MiTAI-based applications. For additional information or to join MSA, see http://www.mitel.com/msa, then select Access Developer Resources.

For more information on Mitel OIG configuration, see the Mitel OIG Installation and Maintenance Guide.
