Best Computer Telephony Integration Software in 2026

Computer telephony integration software brings phone activity into the customer-service tools and systems used around a call. Compared on CRM integrations, supported phone systems, and deployment, the entries also differ in features such as click-to-dial, screen pop, browser extensions, and in-call controls. Free-plan availability and paid-from pricing offer additional points to consider. Think about how calls are made in your workflow and what agents need to see or control while speaking, then check compatibility with your phone systems. KalliopeCTI, TAPIMaster, and Jet Interactive are among the options shown, along with XPhone Connect and ICTContact.
