What is computer telephony integration?
Computer telephony integration (CTI) is the link between a contact centre’s phone system and the software agents use. Without it, the phone and the computer are separate: an agent answers a call, asks for an account number, types it in and waits for the record to load. With CTI, the two work as one. The call arrives, the system recognises the caller, and their record is already on screen.
CTI started as a way to connect traditional office phone systems to desktop computers. Today it’s usually part of a cloud contact centre as a service (CCaaS) platform, connecting telephony with the CRM, ticketing, billing and other business systems.
What CTI does
Common CTI features include:
- Screen pops. The caller’s record opens automatically when the call connects, using their phone number or details captured in the IVR.
- Click-to-dial. Agents call a customer by clicking a number in the CRM rather than typing it, which saves time and avoids misdials on outbound calls.
- Softphone controls. Answer, hold, mute, transfer and conference from the agent desktop, without a physical handset.
- Call data passing. Information collected by the IVR or by a previous agent travels with the call, so a warm transfer doesn’t mean starting again.
- Automatic logging. Call time, duration, outcome and links to the call recording are written to the customer record.
- Agent state integration. The phone system knows when an agent is in a call, in after-call work or available, and routes accordingly.
Why CTI matters
CTI saves seconds on every call, and in a contact centre those seconds add up. Removing manual lookups reduces average handle time. Having the full history on screen helps agents resolve issues first time, improving first contact resolution. Customers notice too: being greeted by name, and not having to repeat their account number to every person they speak to, is a basic part of good customer experience.
CTI also improves data quality. When calls are logged automatically, reporting and analytics are based on what actually happened rather than on agents remembering to fill in notes.
Building towards a single customer view
CTI is one of the foundations of a single customer view. When phone calls, emails, chats and account data all link to one record, any agent can see the customer’s whole relationship with the organisation. That matters most when the customer is in a difficult situation, such as a vulnerable customer during an outage, and the agent needs to understand their circumstances quickly.
Things to check
When evaluating CTI, look at which systems it connects to out of the box, how much configuration is needed to match calls to records reliably, how it handles customers who call from unknown numbers, and whether data flows both ways so the CRM is updated as well as read.
