Why your call center phone system is your brand's frontline

Call centers remain the primary touchpoint between your business and customers. Bad customer experiences can permanently damage your company's reputation, while exceptional service creates loyal advocates who fuel sustainable growth.

"Prior to using Aircall, we had to manually choose to record each call, so if the team member forgot to hit record, we didn't have it, and then they'd have to call the person back to say, 'I'm so sorry I didn't write this down right.' So it would make us look unprofessional. Now if there's an issue, we could just pull up the call recording."

Erica Davis, Founder and CEO of Annie Admin

Your call center phone system effectively becomes the face of your company, making feature selection critical for success.

Basic vs. advanced call center features and how Aircall delivers them

1. Interactive Voice Response (IVR): A core call center phone system feature

Simplify call routing

An IVR system creates an electronic voice menu that guides callers to the right agent based on their specific needs. Modern IVR goes beyond basic "press 1 for sales" options—it uses caller data and smart routing to minimize friction.

The real power of IVR becomes apparent as your call center scales. These systems can handle higher call volumes, support more agents or departments, and manage traffic spikes without hurting performance. When integrated with CRM systems, IVR delivers even more value by providing agents with customer context before the conversation begins.

The result? Higher customer satisfaction, reduced wait times, and agents who can focus on complex conversations rather than call triage.

Interactive Voice Response (IVR) is a call center feature that lets callers interact with a voice menu system using their keypad or voice input. It automatically directs them to the right department or agent based on their selections.

A must-have call center feature, IVR handles higher call volumes efficiently, supports multiple departments, and integrates with CRMs to provide agents with caller context upfront. This reduces wait times and enhances customer satisfaction.

How Aircall customers use this feature:

Aircall’s IVR helps businesses scale support across teams and departments. It integrates with CRMs to streamline call flow and enhance personalization. Customers use it to decrease average wait times by up to 25%.

2. Skill-based routing: Essential in modern call center phone systems

Connect customers with the right expertise

Smart call routing automatically matches incoming calls with the most qualified available agent. This feature analyzes caller information, agent skills, and current availability to ensure every conversation starts on the right foot.

Skill-based routing becomes increasingly important for growing teams and large businesses, where misrouting can create long delays and significantly impact customer experience. Some advanced systems integrate IVR with routing algorithms, creating a seamless experience where callers reach subject matter experts without multiple transfers.

Skill-based routing is a call center feature that ensures each caller is matched with the most qualified available agent based on skillset and availability.

This advanced call routing reduces misdirected calls and long wait times, especially in large or growing teams. Combined with IVR, it improves first-call resolution and overall service quality.

How Aircall customers use this feature:

Aircall’s skill-based routing helps reduce transfers by up to 40% by matching callers with specialized agents. This leads to better resolution times and increased customer satisfaction.

3. Call recording

Capture every important detail

5. Desktop notifications

Never miss critical communications

Real-time desktop notifications keep agents informed about incoming calls, transfers, and important system updates. These pop-up alerts ensure seamless communication flow, especially in busy call center environments where agents juggle multiple tasks.

Desktop notifications become most useful when integrated with CRM or helpdesk systems, giving agents caller context and ticket details instead of just basic alerts. Smart notification systems filter alerts by priority, reducing noise while highlighting urgent customer needs.

"Something that our sales team likes is the Power Dialer. They can call a list of contacts one after the other, which helps streamline our sales process and has increased the number of calls one person makes in a day by 100%"
