The CTI OS application architecture employs three tiers:
•
The CIL is the first tier, providing an application-level interface to

Advantages of CTI OS as a CTI Development Interface
CTI OS brings several major advances to developing custom CTI integration
solutions. The CIL provides an object-oriented and event driven application
programming interface (API), while the CTI OS server does all the ‘heavy-lifting’
of the CTI integration: updating call context information, determining which
buttons to enable on softphones, providing easy access to supervisor features, and
automatically recovering from failover scenarios.
