As a customer-centric business owner, your top priority should be to provide your customers with quality customer service by connecting them to knowledgeable agents with the skills and tools to resolve the issue quickly.

But even your best agents can’t do that if an inefficient, outdated business phone system is slowing them down and causing frustrating miscommunications with customers.

Without call center software, your agents will constantly miss calls, lose valuable time to manual dialing and routine tasks, and face angry customers tired of being kept on hold and having to repeat themselves to multiple agents.

To fix this, you need to upgrade to virtual call center software.

Here, we’ll cover how top virtual call center software and advanced call management features improve agent productivity, streamline customer communication, and drastically improve first call resolution rates.

What is a Virtual Call Center Software?

A virtual call center software is a cloud-based business communication platform allowing customer service agents, sales representatives, and other team members to work remotely as opposed to in a physical call center.

Team members can work with each other and with customers across different time zones, locations, and devices within the software’s unified digital interface.

Thanks to flexibility-focused software features like real-time data syncing, support ticket notifications, and integrations with CRM tools, agents all have access to the same information regardless of when and where they’re working.


How Does a Virtual Call Center Work?

Virtual call centers work by using Voice Over Internet Protocol (VoIP) technology to make/receive telephone calls over the Internet as opposed to the standard PSTN network.

Because VoIP calls take place virtually, users aren’t bound to a traditional landline/desk phone. In addition to desk phones, VoIP users can make/receive calls from devices like desktop computers, smartphones, laptops, and even tablets, allowing for even greater flexibility for any call canter (not to mention major savings on hardware.)

With a virtual call center, agents no longer have to work in a singular location.

The majority of virtual call centers today are cloud-based, meaning the software is hosted on the provider’s server as opposed to onsite. With cloud-based hosting, your business doesn’t need to worry about maintenance, updates, and hardware installation. The provider handles all of that.

On-premise call center software is also available, as an alternative to virtual call center software.

On-premise solutions require a dedicated in-house IT team, enough physical space for the hardware, and mean that your business is responsible for all the hardware maintenance, installation, and accompanying costs. (The good news is that most providers offer paid installation/support plans for on-premise software.)

To get an even better sense of what sets virtual call center software apart from traditional business phone systems, let’s look at what these platforms can do.


Best Virtual Call Center Software Providers

In determining which providers to include in our list of virtual call center software, we considered factors such as:

  • Onboarding support, new customer training, and customer support
  • Available native communication channels
  • Transparency of pricing structure and inclusion of a free trial
  • Ability to integrate with third-party apps, especially CRM systems
  • AI and Automation capabilities
  • Ease of call flow design and editing

The below table shows a brief overview of the top contact center solution providers, what they cost, who should use them, and which of their features stand out.

Cloudtalk call center

CloudTalk is an inbound/outbound support and sales call center solution trusted by over 2,500 current users.

One of the best of CloudTalk’s over 50 advanced calling features is its Real-Time Customer Card tool, which provides caller details like one-click access to recordings of past calls, current and past orders, previous and open support tickets, omnichannel communication history, and notes/comments from previous call center agents. Users can also update the Customer Card or create new support tickets from the card interface during a phone call.

All Customer Card data is available without the need to integrate existing CRM software, though CloudTalk also has a robust set of third-party integrations like Salesforce, Zapier, Zendesk Sell, and Pipedrive.

Features like contact tagging make creating customer groups easy. For example, users can create a contact category for top clients, according to age demographics, by location, or by the urgency of their current support request. Mandatory call tagging, which requires all agents to sort calls into a contact group after every call, is also available.

CloudTalk’s Smart Dialer feature eliminates the need for users to manually add prospects to call lists. Instead, it scans a website the user selects, creates a queued list of phone numbers, and lets users make automated outbound calls with one click. Before they start calling the numbers in the queue, agents can re-order the list and select which phone number they want to make the call from, allowing for local presence. Users can pause the call queue at any time, adjust dialing speed, and automatically reschedule calls that went to voicemail or that weren’t answered.

Five9 call center software

Five9 is an inbound/outbound digital-first cloud omnichannel contact and call center solution. It is designed to improve caller insights at every stage of the customer journey.

It is especially known for its Engagement Workflow, which allows for omnichannel communication and escalation across channels like voice, email, chat, SMS, and social media.

The Engagement Workflow is also designed to offer a high level of customer self-service through the use of Artificial Intelligence (AI) capabilities like Natural Language Processing (NLP) and automation to interpret user intent and provide relevant solutions. Customers can schedule/reschedule appointments, receive shipping updates, take customer surveys, pay bills, and receive outage notifications via a virtual agent, without ever needing to connect to a live one.

Its unique Agent Assist tool not only offers real-time call transcription but also provides live agent coaching and pulls relevant information from the agent knowledge base in real-time, allowing the help desk to better assist the caller. Once the call is finished, Agent Assist automatically generates a Call Summary and uploads it into the company CRM system or customer database.

Five9’s Outbound Dialer integrates with top CRM tools, screens out unanswered calls, do not call phone numbers, and hang-ups to increase agent talk time by up to 300% per hour. In addition to TCPA compliance, the Dialer offers predictive, power, progressive, and preview dialing.

Talkdesk CX Cloud is a call center solution with a 97% CSAT score designed for end-to-end customer experiences.

The new Talkdesk Workspace is a unified and highly personalized interface that shows all an agent’s CX apps, integrations, and current data in one dashboard, eliminating the need to switch between tabs and applications constantly. It also includes a language selector and notification stream, alerting team members to relevant and important events or updates. Users can access the Workspace in their preferred web browser, on a mobile device, or via a downloadable softphone application.

The Workspace is enhanced by Talkdesk’s over 80 AppConnect partnerships. Designed to bypass the lengthy third-party app integration process, AppConnect provides one-click access to pre-integrated agent productivity tools, automation, and more. This allows for a high level of scalability and customization and ensures agents can access any app with a single click from their Workspace.

Additionally, Talkdesk integrates with over 60 third-party communication and collaboration tools, including Slack, Microsoft Teams, Salesforce, Microsoft Dynamics, Zendesk, Zoom, and more.

The 8×8 Speech Analytics interface


8×8 is a cloud contact center solution that, unlike many systems on this list, has its own Native CRM system in addition to third-party CRM integrations.

Agents can view order and interaction history, include attachments, schedule follow-ups, categorize support requests and contacts, and much more from a singular interface. Even if teams still want to use an existing CRM system, they can do so directly from Avaya’s dashboard by importing third-party data into the Avaya native CRM application.

Another excellent feature is 8×8’s Quality Management tool, which makes it easy for new or struggling agents to learn from top-performing reps.

Admins and managers can highlight and share effective interaction moments from call transcripts using the Conversation Highlighter, or offer suggestions to under-performing reps by tagging specific moments in interaction recordings. Search by agent or customer name, transaction codes, call length, and even custom fields to locate calls quickly. Managers can also create their own Call Evaluation Templates.

The Quality Management tool is especially effective thanks to 8×8’s Speech Analytics, which provides annotated call transcripts and lets admins search audio data.

Speech Analytics also has an emotion detection capacity, which analyzes both speaker tone and text-based sentiment to get an even deeper understanding of caller sentiment. It also states what percentage of the cell resulted in Overtalk, where both the caller and the agent are speaking simultaneously (and therefore without clarity.) The Speech Center helps to identify common categories, phrases, and topics within interactions, allowing for easy, drilled-down data.

Aircall call center software

Aircall is a call center software provider known for its user-friendly interface and refreshingly simple setup process.

One of its top features is its “Live Feed” feature, which is especially helpful for small businesses with few agents but a higher call volume. The Live Feed makes it easy to optimize available agent time by providing a complete view of current call center activity. Users can see the number of calls in the queue, the current average speed of answer, the number of calls missed in the past half hour, which customer has the longest current wait time, and current agent status/availability.

Another standout feature is Aircall’s After Call Work tool, which lets agents using an outbound dialer add notes, tag/categorize calls, comment on the interaction, or assign any follow-up calls before it begins dialing the next number. The time for After Call Work is automatically built into any call lasting more than 5 seconds and can be adjusted to last anywhere from 30 seconds to five minutes.

Each user has an individual PBX number or extension for smoother call management, while shared inboxes and shared contacts make assigning work to other agents and collaboration on tasks simple.

It also offers numerous third-party app integrations in its App Marketplace, including Salesforce, Zendesk, HubSpot CRM, Microsoft Teams, HelpScout, and more.

Essential Virtual Call Center Software Features

Features like unlimited calling in the United States and Canada, call queuing, and call hold are all standard for both standard small business phone systems and call centers.

However, certain capabilities that are more like “added bonuses” for VoIP telephony are essential for larger virtual contact centers that have to manage high daily call volumes and an enormous amount of customer data.

Below, we’ve outlined the virtual call center software features that users can’t do without.



Interactive Voice Response (IVR) and Automatic Call Distribution (ACD) allow inbound callers to respond to pre-recorded prompts by speaking their answers or using their phone’s dial tones to enter a response.

IVR provides a high level of customer self-service by offering solutions to common problems or by letting customers complete actions like bill paying, leaving a voicemail message for a particular agent, or getting shipping/order updates without ever having to speak to a live agent.

Admins can create their own unique, fully customizable call path to ensure that callers reach the agent most qualified to help them based on their needs, allowing for higher first call resolution rates and improved customer satisfaction.


Automation and AI

Artificial Intelligence (AI) and automation, like IVR, help keep agents free from basic, repetitive customer service or sales tasks so they can respond to more urgent issues in real-time.

Call center automation can, for example, automatically log call details such as call length, caller contact information, or even schedule a follow-up call so the agent doesn’t have to. It can also automatically dial phone numbers or trigger pre-determined workflows when certain conditions are met.

AI bots can collect customer information, like their phone or account numbers, the reason for their call, and even determine customer sentiment (mood/satisfaction levels) through Natural Language Processing (NLP.)


Third-Party Integrations

Customer Relationship Management (CRM) integration is essential for any contact center.

It enables CTI screen pops that provide key client/caller information while agents are on a call or preparing for one, lets agents take notes and make changes to stored caller data, and automatically syncs any new post-call information to both the CRM system and call center solution.

Other popular integrations can include video calling solutions, team chat messaging and other team collaboration tools, project management apps, and more.


Call Routing and Call Forwarding

Call forwarding protects agent privacy and increases the likelihood that a caller will be connected to the agent by automatically sending calls to additional phone numbers if there’s no answer at the agent’s primary phone number.

Callers will not need to dial another number to be transferred. Instead, they are automatically transferred.

A common call forwarding path is, for example:


Office Phone → Smartphone → Home Phone → Additional Agent → Shared Voicemail


Call routing helps decide how inbound calls are distributed among agents. This keeps things fair and prevents certain agents from becoming overworked.

There are numerous routing methods, including skills-based, which transfers callers to agents based on the skillsets they have to best assist the caller, and most-idle routing, which transfers inbound callers to the agent that has gone the longest without receiving a phone call.


Outbound Dialer Modes

Call centers don’t just receive incoming calls — they make outbound calls, too.

Automated outbound call center dialing modes speed up lead list penetration and prevent agents from losing time on disconnected numbers, unanswered calls, or voice mailboxes. These dialers automatically dial the next phone number on the list while an agent is finishing up their previous call to prevent excessive downtime, and will only transfer the call to the live agent when there’s another person connected and ready to talk on the end of the line. Dialing speeds and modes can be adjusted, as well.


Analytics and Reporting

Quality virtual call center analytics offer both real-time and historical data regarding KPIs and other metrics.

Reports can be entirely customized or built using a premade report template and can be run manually or automatically at a set time.

Common call center analytics to evaluate include:

  • First call resolution rate
  • Daily call volume
  • Number of calls per agent/group/department
  • Percentage of calls that went to voicemail
  • Call abandonment rate and call transfer rate
  • Average call length
  • Popular call tags
  • CSAT (Customer Satisfaction) score
  • Cost per call


The Benefits of Virtual Call Center Software

The most well-known benefit of virtual call center software is the cost savings it offers when compared to a traditional business phone system/call center.

A recent 8×8 study found that switching to virtual call center software can cut transaction costs by an astounding 75%.

But there are many more benefits to call center software than just savings.

They include:

  • Providing a higher level of customer self-service
  • Increased agent productivity
  • Increased first call resolution rates
  • Ease of installation and ease of use
  • Increased employee flexibility and satisfaction, meaning lower turnover rates
  • Deeper insights and analytics into call center agent performance and customer preferences, trends, etc.
  • Third-party software integration means you can access all preferred business communication/collaboration tools from a single interface
  • Higher CSAT rates


Choosing the Right Virtual Call Center Software

Though all the contact center software we’ve mentioned here are among the best, that doesn’t mean that all of them are a good fit for your business.

When evaluating which call center technology to use, be sure to consider factors like:

  • Ease of length of transition to new software
  • Types of new user training available (one-on-one, virtual classes, etc.)
  • Option for a dedicated customer success/tech support manager or support teams
  • Whether or not the solution integrates with your required third-party software
  • Included communication channels
  • Maximum concurrent call volume, call limits, the minimum number of users required per plan
  • Which features are included in the plan you’re considering, and which ones must be added on for an extra fee


Virtual Call Center Software FAQs

Common equipment needed for a virtual call center includes:

  • Desktop computers, mobile devices, hard phones (BYOD supported)
  • Agent headsets
  • Internet connection (DSL/Cable preferred)
  • Bandwidth between 90-156 kbps 

Virtual call center software costs an average of $50.00/user per month to $300.00/user per month and up. 

Costs will vary by the features and provider selected. 

Top factors influencing call center software costs include: 

  • Choosing cloud-based or on-premise software
  • Number of agents 
  • Whether you opt for a monthly or annual payment plan
  • The number of add-on features you select
  • Hardware costs 

Virtual call center software allows agents to work remotely from the location of their choice while remaining connected within the software's interface.

For example, virtual call center team members can:

  • Make and receive calls to customers
  • Collaborate with one another
  • Schedule shifts
  • Access/edit IVR menus, call queues, call routing strategies, call scripts
  • Write call notes and update support ticket status
  • Monitor agents during calls
