What is call volume?
Call volume is a call center metric used to measure the number of inbound calls in a given period. Call center volume is usually measured in different time intervals – hourly, daily, or weekly. Many contact centers categorize call volume into the total number of telephone calls handled by an agent and the total number of calls handled by an automated system (e.g., IVR).
Call center managers put a lot of focus on call volume for several reasons:
- Call volume impacts the agents’ workload, drives call center staffing requirements, and dictates call center expenses.
- This metric helps determine how effective your agents are at working with callers.
- The increase in the current level of your call volume leads to missed calls and a higher call abandonment rate. It has been estimated that call abandonment can cost as much as 40% of lost potential revenues annually.
- Mishandling high call volume results in longer call queues, increased hold times, and your call center’s inability to provide adequate service levels.
What is a high call volume and how to identify it?
Your call center is experiencing high call volume (also called a call volume spike) when the number of your inbound calls is significantly higher than the predicted volume. That basically means the number of incoming calls is more than the actual volume your call center representatives can efficiently handle without compromising your customer satisfaction levels.
Research indicates that the industry standard for high call volume is 10% above the normal level. Yet, that figure can be remarkably higher for smaller or medium-sized businesses due to a lack of available staff.
This dramatic increase in the number of incoming customer calls can be short-term or can last for several hours, days, or even weeks. In addition, call volume usually varies by time of day – e.g., a call center could experience heavy call volume during business hours and light call traffic in the evenings. Other than that, a call center can typically be faced with an increased number of call center inquiries due to one or more of these factors:
- Seasonal spikes: Many businesses experience these spikes annually during holidays or busy periods specific to their industry (such as the Christmas shopping season for retailers).
- Internal issues: Unexpected service outages, website malfunctions, insufficient staff, poorly trained call center operators – that can all lead to increased call volumes.
- Marketing initiatives: Massive promo campaigns or new product launches can also cause high call volume spikes.

How to deal with the high call volume
When call volumes are high, wait times increase, and customer satisfaction drops. Not to mention agents become overwhelmed by a large number of incoming calls and have to work in a stressful environment. This is why high call volume means challenging times for call centers. Here is how businesses can efficiently tackle a high volume of inbound calls utilizing help desk software with a built-in call center such as LiveAgent:
Provide additional service channels
By integrating more channels into your call center software, you can ensure customers interact with your business on their channel of choice while also preventing high call volume. Consider adding a real-time live chat that can also help you adopt a more proactive communication strategy and reduce the number of incoming inquiries altogether.
Develop self-service resources
Creating accurate and comprehensive self-service resources (like a knowledge base and FAQs) can reduce the need for customers to get on the phone in the first place. This is particularly helpful when agents typically receive repetitive questions over and over again. These questions can be answered in your FAQ section, especially if it’s visible and easily accessible on your website.
Optimize your IVR
Along with automatic call distributor (ACD), Interactive Voice Response (IVR) systems can help businesses gain complete control over the flow of inbound calls by efficiently routing them to the most appropriate agents. In times of high call volumes, you can additionally optimize your IVR by directing callers to your self-help resources and allowing them to leave a voicemail. Doing so can reduce the number of calls agents have to answer.
Offer a call-back option
Call volume spikes can also be eliminated by enabling call back solutions that are available with most call center software. In LiveAgent, for instance, when a caller requests a call back, their phone number is kept in a call queue and automatically dialed once the agent can handle their call.
Analyze your call center data
By keeping close tabs on your call center analytics, you can get a better sense of when call volume spikes occur and how each call center agent performs during busy times. Track key call center metrics and KPIs (such as average handle time, average speed of answer, missed calls) and use this historical data to look for any patterns and trends of spikes in call volume. This will help you plan agent scheduling more efficiently and ensure you have enough staff to meet all your call center service needs.

Expert note
Call volume is a critical metric that measures the number of incoming calls to a call center. Analyzing call volume trends can help businesses identify high traffic periods and allocate resources more efficiently.

Call centers require specialized phone systems for effective customer support, with IP, VoIP, and mobile phone systems among the most common types. Call center agents also need other equipment such as computers, headsets with microphones, and call center software for call management and operations. Choosing the right call center phone system involves considering advanced features, processing times, security standards, payment and routing options, as well as support for self-service and multi-channel communications. LiveAgent offers numerous features and integrations for call centers looking to improve their services.
Call center compliance involves following certain rules, such as call center security and PCI compliance. Personal data breaches and internal threats, such as temporary employees or internal hackers, pose significant risks to call centers. External threats are also on the rise. Improving call center security is essential to avoid damage to reputation, penalties, and staff retention. The PCI-DSS standard is important for improving payment data storage. Adhering to PCI compliance entails encrypting sensitive data, implementing access control measures and avoiding certain practices that can compromise security.
Call center supervisors are essential to providing great customer service through traditional phone support. They train agents, oversee daily operations, manage databases, and ensure the company's goals are met. Their duties also include performance evaluation, customer service management, and assisting employees. To be successful, they need strong management, communication, leadership, and problem-solving skills, as well as a desire for self-improvement. Thus, it is important to hire skilled supervisors who possess these traits.
What is Call Center Technology?
Call center technology refers to the tools, both software and hardware, used by call centers for inbound and outbound calls. Cloud-based call centers, omnichannel support, and self-service tools are among the emerging trends in call center technology. Software solutions like LiveAgent offer features like SIP trunking and VoIP services to help businesses improve their communication with customers. The technology works through a private cloud, utilizing voice over internet protocol and intelligent customer routing. Essential components of call center technology include VoIP softphones, IVR, voicemail messages, pre-recorded responses, and call center queue management options.
