Call Center Phone Systems: Find the Right Virtual Solution


In today's customer-centric business world, efficiently managing customer interactions is very important. This is where call center phone systems come into play. These specialized telecommunication systems are designed to handle the high volume of inbound and outbound calls that businesses receive, ensuring smooth and efficient customer service operations. From seamlessly routing calls to providing interactive self-service options, call center phone systems are packed with features like Automatic Call Distribution (ACD), Interactive Voice Response (IVR), and advanced analytics, all working together to enhance customer satisfaction and optimize business performance. While looking to outsource your telecalling operations to a BPO call center, placing importance on technology is equally important as their telecalling operations. Call center technology offers a wide range of benefits, like:

  • Streamlining operations by automating repetitive tasks.
  • Enhances data management by providing tools to organize and analyze customer data.
  • Ensures personalized service by analysis of lead scales.
  • Maintains quality through consistent call recording and monitoring.
  • Otimizes costs by automating tasks and improving agent efficiency.
  • Supports multichannel interactions, vital for competitiveness and customer satisfaction.

Squadstack is a tech-first telecalling partner that provides you with trained telecallers, virtual call center phone systems, and an excellent tech stack to drive connectivity and boost sales. Our AI-integrated agent interface helps our agents with system-driven outreach and FAQs to equip them with resources that ensure a satisfactory experience for your leads.

Call Center Phone Systems: Leverage the Tech-First Approach

Leveraging our advance call center technologies, which include an analytics dashboard, can help you identify lead behavior for personalized marketing campaigns. Let’s take a closer look at our call center technology stack below on the page:

Dialer Technology

Dialers automate the repetitive task of dialing phone numbers and handle busy lines. This frees up the agents to focus on productive conversations with potential customers. Dialer technology is essential for call center operations as it enables organizations to optimize agent productivity, improve customer interactions, and effectively achieve business objectives.

Let’s take a look at how our call center phone system technology works:

Auto Dialer

Our auto dialer streamlines telecalling by eliminating the search process. It automatically contacts potential customers, freeing agents from time-consuming tasks, self-selection, and phone calls. This simplifies work, increases agent productivity in a call center, and allows time to be spent interacting with customers instead of using the phone. Our automatic dialers eliminate the burden of making calls, allowing employees to focus on providing quality service and achieving business goals.

Parallel Dialer

Our parallel dialing feature offers efficiency and scalability in call center operations. With the ability to simultaneously dial multiple leads per agent, we maximize outreach potential and optimize agent productivity.

In a 1:2 pacing ratio, two leads are dialed per agent, ensuring that the first to answer is seamlessly connected while disconnecting the others. This innovative approach to dialing enables call centers to reach more prospects in less time, driving higher contact rates and improving overall campaign performance.

Predictive Dialer

A predictive dialer streamlines outbound calling by leveraging predictive algorithms to initiate calls based on predicted agent availability.

As agents complete calls and become available, the system automatically places calls to ensure a continuous flow of conversations. With a 1:2 pacing ratio, the phone system initiates twice as many calls as available agents, maximizing connection opportunities and optimizing resource utilization in a call center.

By intelligently managing call volumes and agent availability, our predictive dialer enhances operational efficiency, increases contact rates, and drives better outcomes for our clients.

WEBRTC (Web Real-Time Communication)

WebRTC (Web Real-Time Communication) is a technology that enables direct real-time communication between web browsers or applications. It’s essentially a set of technologies that web browsers and even mobile apps can use to communicate directly with each other in real-time without needing to rely on additional software or plugins.

With WebRTC, we've streamlined our calling stack by eliminating mobile phones and enabling all calls through computers. Integrating predictive dialers has enhanced efficiency. This technology empowers seamless, browser-based communication, making it ideal for various call center operations. As demand grows, we'll adapt and innovate, leveraging WebRTC's flexibility to meet evolving needs in communication and beyond.

How to Manage Call Center Phone Systems

ACD (Automatic Call Distributor)

ACD (Automatic Call Distributor) phone systems are designed to handle incoming calls efficiently. They employ sophisticated algorithms to route calls based on various factors, including caller information, IVR selections, agent availability, and skills required for specific call types.

By distributing calls to the most appropriate agents or departments, ACD systems minimize wait times, reduce call abandonment rates, and ensure that customers are quickly connected to the right person to address their needs.

Here's a breakdown of how ACD works:

ACD Call Center Phone System Handles Incoming Calls
Image: The ACD (Automatic Call Distributor) Call Center Phone System Handles Incoming Calls
  • Routes incoming calls: An ACD system acts like a traffic controller, receiving inbound calls and directing them to the most suitable available agents.
  • Uses predefined rules: These rules can consider factors like caller ID, dialed number, time of day, and caller selections from Interactive Voice Response (IVR) systems.
  • Prioritizes available agents: It checks for available agents and assigns calls to them based on these priorities. If no agents are free, callers might be placed in a queue.

Interactive Voice Response (IVR)

In telecalling, Interactive Voice Response (IVR) acts as an automated receptionist that interacts with callers using pre-recorded messages and touch-tone inputs (pressing numbers on their keypad) or voice recognition.

IVR saves money by handling basic calls 24/7, freeing call center agents for complex issues, and improving customer self-service options. Here’s how it works:

  • Greets & Guides: IVR welcomes callers with a message and offers a menu of options, typically voiced instructions with corresponding numbers to press.
  • Collects Input: Callers navigate the menu using touch tones or voice recognition, selecting options relevant to their needs.
  • Routes or Informs: Based on the chosen option, IVR can route callers to specific agents, deliver pre-recorded information, or direct them to self-service channels.

Omnichannel Outreach

An omnichannel outreach strategy is a comprehensive approach that integrates multiple communication channels—voice, email, chat, social media, and SMS—into a unified platform.

This strategy ensures a seamless customer experience across all online and offline touchpoints. Unlike multichannel strategies that use communication channels independently, omnichannel outreach merges these channels to provide a cohesive customer journey.

By leveraging social media, mobile applications, email, and website data, businesses can actively engage prospective customers and boost sales, leads, and profits.

Advantages of Omnichannel Outreach

Implementing an effective omnichannel strategy involves understanding customer behavior, identifying the most effective channels, and leveraging customer data for insights. Let’s look at the advantages of omnichannel outreach:

  • Wider Reach & Profits: Engage customers on more channels to boost conversions and revenue.
  • Data-Driven Decisions: Track customer journeys and preferences to optimize outreach strategies.
  • Stronger Brand: Maintain a consistent presence across channels for better brand awareness and loyalty.
  • Happier Customers: Seamless interactions lead to higher satisfaction and retention.
  • Competitive Advantage: Stand out with superior customer experiences.

Quality Assurance

Quality Assurance (QA) is a procedure that helps ensure that customer interactions are consistent with corporate objectives and goals. Quality assurance helps to detect inefficiencies in customer support, improve the customer experience, and standardize customer communication methods.

SquadStack's telecalling platform incorporates an AI-powered system for ongoing quality monitoring, a critical aspect of ensuring call excellence. The Automated Quality Check (AQC) engine streamlines quality assessment, eliminating manual processes and offering scalability. It's estimated to deliver 3-5 times more cost efficiency than conventional methods. Providing real-time audits, pinpointing areas for enhancement, and flagging irregularities, the AQC engine is highly adaptable and reduces the human effort that goes into Quality assurance.

Benefits of QA

Quality of service is a critical factor in a call center and directly impacts your company's brand reputation. Let’s look at the benefits of having an efficient QA process:

  • Boosts Customer Satisfaction: QA ensures calls meet quality standards, leading to better customer experiences. Call center agents follow best practices for resolving issues politely and efficiently, resulting in happier customers.
  • Improves Agent Performance: Through call reviews and feedback, QA identifies areas where agents can improve. This can involve better product knowledge, more vital communication skills, or following specific procedures. By addressing these areas, agents become more effective and confident.
  • Enhances Efficiency and Reduces Costs: Effective QA helps identify coaching needs and areas for improvement in call center processes. This can lead to fewer repeat calls, faster resolution times, and, ultimately, lower operational costs.

Conversion Stack

The conversion stack implemented by SquadStack plays a pivotal role in achieving enhanced conversions while ensuring a reasonable Customer Acquisition Cost (CAC). Once sufficient data is gathered for analysis, SquadStack's conversion stack comes into play. It comprises various components:

  • Prioritization of Leads: SquadStack segments leads into 3-4 buckets based on past conversion patterns derived from metadata analysis.
  • Callback Requests Prioritization: Leads requesting callbacks are given precedence.
  • Lead Time to Action Prioritization: If there's a correlation between Time to Action and conversion, leads are prioritized accordingly to minimize Time to Action.
  • Mapping Top Agents to Top Leads: SquadStack identifies top-performing agents based on qualifications, conversions, quality, and productivity metrics and matches them with leads in the top buckets.
  • Agent Performance Monitoring: SquadStack regularly assesses agent performance, including refresher training and feedback sessions. Agents failing to meet standards may have their lead allocations restricted or removed from the campaign.
  • Follow-up Cadence: Leads receive multiple follow-ups with appropriate intervals to ensure a positive lead experience. To maintain acceptable CAC or improve Gross Margin (GM) for success-based customers, SquadStack employs additional strategies.
  • Identifying Low Conversion Leads: SquadStack identifies leads with low conversion rates or those showing no positive outcomes despite significant attempts.
  • Alternative Outreach Channels: Cheaper outreach channels like WhatsApp or IVR are introduced by SquadStack to nurture paused leads.
  • Reduced Calling Cadence: SquadStack implements a reduced calling frequency for paused leads.
  • Smart Reactivation: Leads are reactivated by SquadStack based on previous attempts and outcomes, optimizing re-engagement efforts.

Implementing these strategies ensures that SquadStack's conversion stack efficiently prioritizes leads, allocates agents effectively, and optimizes follow-up processes, leading to improved conversions while maintaining cost-effectiveness.

Workflow Builder

With our Workflow Builder at SquadStack, we allow flexibility to the operations teams. For instance, they can configure workflows to initiate outreach via various channels, such as WhatsApp or IVR, depending on lead characteristics. Following the initial outreach, the system dynamically progresses leads based on responses received, ensuring a seamless journey through subsequent touchpoints within the workflow.

For example, a lead responds to a WhatsApp message with a specific action, such as pressing a key in an IVR menu. In that case, the system automatically directs them to the next relevant step in the workflow. Moreover, in cases where initial contact attempts fail to connect with the lead, our system intelligently reschedules follow-up attempts for optimal outreach effectiveness.

One of the key features of our Workflow Builder is its adaptability to varying lead availability and preferences. Operations teams can input parameters such as time intervals for follow-up attempts and delays between outreach channels, ensuring that outreach efforts are synchronized with lead availability. Furthermore, these parameters can be adjusted based on lead data, allowing for personalized outreach tailored to specific lead profiles.

For example, suppose a lead is identified as an office-goer with availability typically around early morning or evening due to work commitments. In that case, the system can be configured to schedule outreach during these times. Conversely, outreach efforts can be timed accordingly for a homemaker lead who is more likely to be available during daytime hours.

Script Builder

In our app, agents are presented with a guided script flow designed to facilitate efficient interactions with leads. This script flow is highly customizable, allowing us to configure standard elements such as greetings, introductions, and questions to capture essential details from the lead. Additionally, we have the flexibility to specify whether specific information captured during the interaction should be included in the customer report.

The script comprises various "form elements" or questions agents must navigate during the conversation. These questions can take different formats, including multiple-choice, single-choice, or text-based responses. Moreover, our system incorporates validations to ensure the proper sequencing of questions. For instance, the greeting question must always precede other questions in the script for the script to be published and used effectively.

In addition to the scripted flow, agents are equipped with supplementary resources to assist them during calls. Our operations team curates and adds these resources, such as battle cards, tutorials, and FAQs, to the system. By providing agents access to these resources, we empower them to address lead inquiries more effectively and confidently handle various scenarios.

Post-Call Surveys

Post-call surveys in call centers are structured feedback mechanisms designed to evaluate customer satisfaction and gather insights immediately following a customer interaction with a call center agent. Let’s look at the advantages of post-call surveys:

  • Immediate feedback for prompt issue resolution
  • Enhance customer satisfaction and loyalty
  • Identify areas for improvement in agent performance and processes
  • Promote data-driven decision-making
  • Foster customer engagement and empathy
  • Drive continuous improvement efforts for better service delivery and retention.

Call Transfer

The Live Call transfer feature facilitates seamless transfer of calls between a Sales Executive (SE), a lead, and a Customer Support Expert (CSR). During a call between the SE and the lead, the SE offers the option of transferring to a CSR for further assistance. If the lead agrees, the SE initiates the transfer process by putting the lead on hold and clicking the "Call CSR" button.

This prompts a connection attempt, which may take up to 60-90 seconds. Once connected, the SE verbally briefs the CSR on the context before transferring the call. After connecting the CSR to the lead, the SE advises the lead to accept the incoming call from the CSR and ends the current call. The SE then proceeds to the next screen on the app, adds any necessary comments, and submits the mission. In case of an unsuccessful connection with a CSR, the SE is prompted to schedule a callback. If the lead declines the transfer, the SE can proceed to schedule a callback directly. This feature streamlines the process of transferring calls while ensuring effective communication between the SE, lead, and CSR.
