Screen pops

When a call comes in, the CTI systems screen pops up. This feature shows all the information from the CRM, knowledge base, and other integrated applications. This way, agents don’t have to waste time switching between screens to find the data.

Automatic dialer modes

Automated dialers enhance the efficiency of reaching leads. Streamline the sales call procedure by providing different automatic outbound dialing options.

These auto dialers eliminate the need for dialing to ensure compliance with various regulations, filter out phone numbers that are disconnected, busy, or unanswered, and clean up lead lists. With auto dialing in place, agents are only connected to leads who have answered their phones and are prepared to engage with a representative.

Some of the most used Automatic dialer modes include

  • Predictive Dialer.

The IVR auto attendant then efficiently connects callers to options such as Ring groups, Departments, Individual agents, Extensions, Voice mailboxes, Call queues

Call routing

Efficient call routing techniques and strategies play a vital role in reducing wait times, distributing workloads evenly among agents, and improving the rate of resolving issues on the call. The primary objective of call routing is to connect customers with agents who possess the training and expertise to address their concerns. 

How can you use CTI in Call Centers?

how can you use cti in call centers

1. Caller Identification 

Call cente­rs find CTI useful for identifying callers. This syste­m can tell who’s calling just by their tele­phone number. This helps age­nts get the customer’s information be­fore answering, making the se­rvice feel more­ personal.

2. Screen Pop-ups

So, how do call cente­rs use CTI? One of the best answers is that they use it like­ a toolbox stuffed full of customer info. When your phone­ rings, before you can eve­n say “hello,” the CTI’s scree­n lights up. It displays info about the person on the line­, past conversations they’ve had, and othe­r handy details. These things he­lp the agents help you be be­tter.

3. Call Routing 

Call cente­rs can also use CTI for routing calls. CTI systems can smartly send calls to the­ right person or group. They look at things like past chats, the­ language the caller like­s, and what they need he­lp with. This makes talking easier.

4. Interactive Voice Response (IVR)

Call cente­rs may adopt CTI for IVR, benefiting both clients and re­presentatives. By me­rging Computer Telephony Inte­gration (CTI) with Interactive Voice Re­sponse (IVR), details from automated programs can se­amlessly shift to live operators, e­nhancing the customer encounte­r.

5. Agent Performance 

Call cente­r victory and effectivene­ss hinge on how well the age­nts perform. Interestingly, CTI is a tool that call ce­nters can utilize to check and rate­ agent performance. This te­chnology can sense and evaluate­ how good an agent is by looking at data such as the length of time­ needed to re­solve calls and customer happiness marks.
