Still struggling with messy call data reports?

If you’re evaluating unified communications software, you know how limited reporting and short data retention can leave your telecom spend and productivity in the dark.

But in reality, missing crucial insights from old call data makes it tough to control costs or confidently answer audit and compliance queries.

That’s exactly the pain ISI targets, with Infortel Select designed to bring unlimited call data retention, deep analytics, and easy multi-platform integration together—so your team can finally see the full telecom picture, not just glimpses. I’ve spent time digging into how ISI approaches call data with features like customizable dashboards, cradle-to-grave analytics, and secure, compliant storage to solve these problems with far less effort.

In this review, I’ll break down how you can finally eliminate hidden telecom costs and gain reliable, actionable reporting that goes beyond your UC platform’s basics.

You’ll find a full ISI review—from core features and practical use cases to transparent pricing, implementation requirements, and how ISI stacks up against other alternatives—so you can make the right call for your organization.

You’ll walk away with the features you need to compare, the pitfalls you can avoid, and clear next steps for your software decision.

Let’s dive into the analysis.

ISI Overview

Based in Schaumburg, Illinois, ISI has focused on telecom management since 1977. I find their mission is refreshingly straightforward: helping businesses measure, analyze, and optimize the costs tied to unified communications.

They specialize in call detail reporting for diverse industries like healthcare, lodging, and professional services. To me, what’s key is their focus on enhancing native UC platforms, which often have surprisingly poor built-in reporting capabilities.

Now owned by Valent Capital, their cloud-based Infortel Select platform shows a clear modernization strategy. I will explore its practical impact through this ISI review.

Unlike broader TEM tools like Calero-MDSL, which can feel overwhelming, ISI doesn’t try to manage all your tech spend. I find they offer specialized analytics for modern UC platforms, a much more practical approach.

They work with a wide range of organizations, from mid-market firms to large enterprises that must track detailed call data for tough compliance requirements or for precise, department-level cost allocation.

From my perspective, their strategy is laser-focused on solving the frustrating data gaps inherent in platforms like Microsoft Teams and Cisco, prioritizing unlimited data retention and compliance—a major pain point I hear about often.

Now let’s examine their capabilities.

ISI Features

Are you struggling with limited call data and poor reporting?

ISI features within their Infortel Select solution can help you gain deep insights into your unified communications. Here are the five main ISI features that transform your telecom data.

1. Enhanced Search & Reporting

Tired of basic, unhelpful call reports?

Native UC platforms often offer only surface-level data, which makes it hard to pinpoint actual call patterns. This leaves you guessing about performance.

Infortel Select provides access to over 50 call detail fields and offers customizable dashboards and pre-defined reports. From my testing, the custom report designer truly shines, allowing for granular analysis. This feature means you can scrutinize call data at a minute level, identifying crucial trends.

So you can finally get the detailed insights you need to make informed decisions about call management.

2. Unlimited Data Retention

Worried about losing historical call data?

Many platforms delete call data after a short period, which hinders long-term analysis and compliance efforts. This creates compliance headaches for your team.

ISI offers indefinite data retention, which is crucial for historical record-keeping and meeting compliance needs. What I love about this feature is that no valuable call data is ever lost, regardless of how old it is. This ensures you always have the necessary information for audits or trend analysis.

This means you’ll always have access to complete historical call records, which is vital for long-term strategic planning.

3. Call Accounting & Cost Allocation

Can’t pinpoint where telecom costs are going?

Without precise allocation, it’s hard to know which departments or projects are driving your telecom expenses. This often leads to uncontrolled spending.

This feature gives you a precise understanding of telecom usage and helps allocate costs across departments or cost centers. Here’s what I found: granular cost breakdowns facilitate informed business decisions, helping you reduce unnecessary spend. You can assign variable usage, fixed charges, and one-time fees.

The result is your business can accurately track and manage telecom expenses, which could lead to significant savings.

4. Employee Productivity & Performance Monitoring

Struggling to assess team call performance?

It’s tough to identify high and low performers when you lack clear data on call volumes and handling. This makes optimizing your workforce difficult.

Infortel Select provides metrics to measure and monitor employee productivity related to call activities. This is where ISI shines, helping you identify high and low performers with ease. You can track inbound, outbound, and internal call volumes.

So you can optimize staffing levels and improve overall workforce efficiency with data-driven insights.

5. Caller Experience & Queue Analytics

Are callers waiting too long in queues?

Poor visibility into call queues can lead to long wait times and abandoned calls, hurting customer satisfaction. This negatively impacts your customer service.

The solution offers a “Cradle-to-Grave” view of the caller’s journey, providing insights into queue performance. What I appreciate is its ability to reveal wait times, abandoned call rates, and agent availability, without a full contact center solution. This visibility helps optimize your call center operations.

This means you can significantly improve customer satisfaction by identifying and resolving bottlenecks in your call handling.

These ISI features within Infortel Select work together to create a comprehensive UC analytics platform that transforms raw call data into actionable business intelligence.

ISI Pricing

Confused about what you’ll actually pay monthly?

ISI pricing is primarily custom, requiring you to contact sales for a tailored quote based on your specific needs, though some initial figures are available.

1. Pricing Model & Cost Factors

Their custom pricing approach.

ISI’s pricing for Infortel Select is not one-size-fits-all, largely depending on your user count, desired features, and deployment (cloud vs. on-premise). What drives the total ISI pricing are factors like specific analytics needs and integration requirements across various UC platforms.

From my cost analysis, this means your costs are directly tied to your specific operational scale and features.

2. Value Assessment & ROI

How does this investment pay off?

What I found regarding pricing is that while you don’t get upfront rates, the custom quote ensures you only pay for what your business truly needs. This helps you avoid overspending on unused features, leading to stronger ROI by optimizing telecom expenses and improving productivity.

Budget-wise, this personalized approach allows you to justify the expense against tangible operational improvements.

3. Budget Planning & Implementation

Prepare for the full investment.

Beyond the core subscription, consider the time and potential costs for setup, especially with complex integrations across disparate UC systems. From my research, you should budget for implementation services to ensure a smooth deployment and maximize the solution’s value from day one.

This means you can plan your total cost of ownership more accurately, helping your finance team with forecasting.

My Take: ISI’s pricing strategy focuses on delivering tailored solutions for UC analytics, making it ideal for businesses of all sizes that need precise cost allocation and performance insights.

The overall ISI pricing reflects customized value for complex telecom environments.

Steep learning curve concerns emerge.

While overwhelmingly positive, older ISI reviews sometimes mention the “user interface can be overwhelming from all the choices.” What stands out in user feedback is how extensive functionality might imply a learning curve, especially for those new to telecom analytics tools.

This suggests you might need some time to explore the full range of features.

The overall ISI reviews reflect credible patterns of user satisfaction, with powerful features and significant ROI standing out.

Best ISI Alternatives

Unsure which UC analytics platform to choose?

The best ISI alternatives include several strong options, each better suited for different business situations, budget considerations, and specific unified communications needs.

1. Calero-MDSL

Need full-spectrum technology expense management?

Calero-MDSL excels when your primary need is end-to-end Technology Expense Management (TEM) for all IT and telecom spend, beyond just call data. From my competitive analysis, Calero offers a broader suite for holistic financial management, though it’s typically geared towards larger enterprises with custom pricing.

Choose Calero if your priority is comprehensive financial oversight across all technology services, not just call analytics.

2. Management of Things (MoT)

Looking for automated network expense control?

MoT provides a SaaS solution focused on automating workflows for network service and asset management, identifying billing errors. What I found comparing options is that MoT emphasizes automated expense management and asset control across your network, while ISI focuses more on deep call analytics.

Consider this alternative when your focus is on broad network operations and expense optimization, rather than just call performance.

3. WinCall (by TeleManagement Technologies)

Still running traditional, on-premise PBX systems?

WinCall is a sophisticated call accounting software ideal for established, on-premise PBX environments where a proven, traditional system is preferred. From my analysis, WinCall suits legacy on-premise telecom setups better, whereas ISI’s cloud-native Infortel Select shines with modern UC platforms and advanced analytics.

Choose WinCall if your environment is primarily on-premise and you require a well-established, traditional call accounting system.

4. @Comm’s CommView Plus

Want broad-based, near real-time call accounting?

CommView Plus offers a browser-based call accounting and reporting solution integrating with various PBX/VoIP systems for near real-time data. Alternative-wise, CommView Plus offers solid broad-based call accounting, especially if you value immediate data from diverse systems over ISI’s deeper UC-specific analytics and compliance features.

Choose CommView Plus for a flexible, general-purpose call accounting solution with strong real-time data capabilities.

The best ISI alternatives depend on your specific unified communications environment and expense management priorities.

ISI Setup

Concerned about complicated software setup and training?

For an ISI review, understanding the deployment process is key. This section analyzes ISI’s implementation, helping you set realistic expectations for time, resources, and potential challenges your business might encounter.

1. Setup Complexity & Timeline

This isn’t always a ‘set it and forget it’ solution.

ISI setup complexity varies with deployment choice; cloud options offload more administrative burden, while on-site installations require more internal IT involvement. From my implementation analysis, the process is designed to be streamlined with ISI’s guidance, reducing customer burden.

You’ll need to plan for data transfer methods and configuration, particularly for automated updates and secure FTP.

2. Technical Requirements & Integration

Expect some technical collaboration with your IT team.

For remote support and data transfer, ISI typically requires remote access and potentially SFTP setup, though they can provide necessary software or hardware. What I found about deployment is that ISI works with your existing infrastructure, leveraging Microsoft Azure for robust security and performance.

Plan for IT readiness regarding network configurations, port openings, and the necessary security protocols for data transmission.

3. Training & Change Management

Successful adoption hinges on proper user engagement.

ISI offers comprehensive training, including web-based sessions and dedicated Customer Account Coordinators (CACs) to guide your team. From my analysis, the UI can be overwhelming for some users initially due to extensive choices, so targeted training is vital.

Invest in these training resources and consider additional specialized sessions to ensure all users confidently leverage the system’s full capabilities.

4. Support & Success Factors

Vendor support is a critical part of your journey.

ISI provides support through a National Technical Assistance Center (TAC) and a dedicated CAC, offering a single point of contact from implementation through ongoing reporting. What I found about deployment is that their ISO 9001 certification underscores their commitment to quality and proactive issue resolution.

Factor in leveraging their remote diagnostics and consistent communication with your CAC for a smoother, more successful deployment and ongoing operation.

Overall, successful ISI setup requires collaborative planning and leveraging vendor support to navigate its capabilities, ensuring your business maximizes its investment effectively.
