3. First Call Resolution (FCR)

The percentage of calls resolved during the initial contact between a caller and an agent, without the need for follow-up or escalations.

4. Average Hold Time

The average time callers spend on hold before being connected to an agent.

5. Abandoned Call Rate

The percentage of calls in which the caller disconnects before reaching an agent.

6. Call Blockage

The percentage of calls that are not connected due to network limitations, busy signals, or other technical issues.

7. Call Transfer Rate

The percentage of calls transferred from one agent or department to another.

10. Occupancy Rate

The percentage of time an agent is actively engaged in call-related work, including talk time, hold time, and post-call work time.

11. Average Speed of Answer (ASA)

Phone Metrics Explained

Phone metrics play a crucial role in measuring the performance and efficiency of a call center or customer support organization. Metrics such as Call Volume and Call Duration provide insights into the amount and complexity of customer interactions, thereby helping to understand staffing and training requirements. First Call Resolution (FCR), Average Hold Time, Abandoned Call Rate, Call Blockage, and Call Transfer Rate all help to identify potential issues with call handling and the overall caller experience. These metrics contribute to shaping and improving procedures or policies resulting in enhanced customer satisfaction. Talk Time, Post-Call Work Time, and Occupancy Rate help to gauge agents’ workload and efficiency, while Average Speed of Answer (ASA), Service Level, Customer Satisfaction (CSAT), and Net Promoter Score (NPS) offer valuable data on customer perception of the organization’s services.

Furthermore, Agent Attrition and Agent Adherence metrics provide information on workforce stability, engagement, and scheduling effectiveness. Lastly, Handle Time delivers a comprehensive understanding of the overall time spent on each call, which aids in optimizing resource allocation and streamlining operational processes. Collectively, these phone metrics are essential for monitoring and improving call center performance to ensure high levels of customer satisfaction and business growth.


In summary, phone metrics continue to be a crucial aspect of any modern business’ strategy, providing invaluable insights into customer engagement, agent performance, and overall operational efficiency. By regularly analyzing and optimizing these metrics, businesses can not only enhance their customer experience but also streamline internal activities and inform future decision-making.

As technology continues to evolve and customer expectations grow, staying informed on the latest phone metrics and best practices is essential for any company looking to maintain a competitive edge in today’s rapidly changing business landscape. Consequently, investing time and resources in understanding and optimizing phone metrics can undoubtedly yield long-term benefits and positively impact a company’s bottom line.



What are phone metrics and why do they matter in business?

Phone metrics provide valuable data on various aspects of your phone system's performance such as call volume, average call duration, missed calls, response time, and caller satisfaction. These insights help businesses make informed decisions about staffing, training, and customer service improvements, ultimately leading to increased efficiency, customer retention, and revenue growth.

Which phone metrics should businesses track to improve customer experience?

Key phone metrics businesses should track include call volume, average handling time, call abandonment rate, first call resolution, and service level. Monitoring these metrics helps businesses identify areas for improvement, which can positively impact customer satisfaction and loyalty.

How can phone metrics help a business identify staffing needs?

By analyzing phone metrics such as call volume, average handling time, and time of day patterns, a business can identify peak and low call times. This information enables management to allocate human resources more effectively, ensuring reduced wait times, increased customer satisfaction, and optimal staffing levels at different times.

How do phone metrics play a role in staff training and performance evaluation?

Phone metrics can reveal gaps in staff training by identifying trends in long call durations, inefficient call resolution rates, or high call abandonment rates.
