What is CTI software?

Software that links telephone systems with computer applications, usually a CRM, so calls trigger screen-pops, click-to-dial and automatic call logging.

Which CRMs support CTI?

Salesforce Open CTI, Microsoft Dynamics 365 Channel Integration, HubSpot, Zendesk and Zoho all expose CTI frameworks.

How much does CTI software cost?

Integration layers and CCaaS seats are usually priced per agent per month; most vendors quote enterprise pricing on request.

What should I check before buying?

CRM compatibility, logging accuracy, recording compliance, routing needs and total per-agent cost.

Best CTI Software in 2026

Computer telephony integration (CTI) software connects your phone system to your CRM so agents see caller records on screen, dial with one click and log every call automatically. The right tool depends on your CRM, your existing telephony and whether you need a full contact center or just an integration layer.

Buyer's Guide

How to Choose CTI Software

Everything you need to know before choosing a cti software solution — features, pricing, evaluation criteria, and answers to common questions.

Start with your CRM and phone system

List the CRM (Salesforce, Dynamics 365, HubSpot, Zendesk) and the telephony platform you already run. Some CTI tools are integration layers on top of existing phones; others are full cloud contact centers with CTI built in.

Check screen-pop and logging depth

Confirm caller matching rules, automatic activity logging, call recording links and disposition codes write back to the right CRM objects without manual entry.

Review routing and analytics

If you need skills-based routing, IVR, queues and real-time dashboards, a CCaaS platform is the better fit than a lightweight connector.

Validate compliance and reliability

Check call recording consent controls, PCI pause-and-resume, data residency and uptime SLAs before rollout.
