Why Companies Are Moving from CUCM to Webex Calling
Cisco’s cloud calling platform, Webex Calling, gives CUCM customers a clear modernization path — without leaving the Cisco ecosystem. With built-in Customer Experience features, simplified IT operations, and Cisco’s own self-service migration tools in Control Hub, the transition is more accessible than ever.
But moving to the cloud also means adapting to a new reporting reality. Native Webex Control Hub analytics have significant limitations — and that’s where ISI Analytics fills the gap.
The Webex Calling Advantage
Stay with Cisco
Leverage existing Cisco expertise and vendor relationships while moving to the cloud.
Free Migration Tools
Cisco provides self-service migration tools built into Control Hub at no additional cost, including automated firmware migration licensing.
CX Without the Contact Center
Webex Customer Experience Essentials delivers contact center-like capabilities — without the complexity or cost of UCCX.
Unified Cloud Platform
Voice, video, messaging, and collaboration in one cloud-native solution managed from Control Hub.
Hybrid Flexibility
Cisco's Flex Plan lets you run CUCM and Webex Calling simultaneously under one subscription for phased migrations at your own pace.
Reuse Your Phones
Cisco IP Phone 7800 and 8800 series can be converted to Webex Calling via automated MPP firmware migration.
Customer Experience Features Without the Contact Center Complexity
Moving to Webex Calling unlocks Customer Experience capabilities that previously required a full UCCX deployment. Webex Calling Professional includes basic Auto Attendants and Call Queues. Adding Customer Experience Basic (included free) gives you Voice Queues with skills-based routing and agent management. Stepping up to CX Essentials adds real-time agent monitoring, supervisor whisper/barge, screen pop, and historical analytics.
For organizations migrating from CUCM + Hunt Groups or CUCM + UCCX, Webex CX Essentials provides the core contact center capabilities most teams actually need — without the infrastructure overhead.

Where Webex Control Hub Reporting Falls Short
Webex Calling is a powerful platform — but its native reporting in Control Hub has real limitations that affect day-to-day operations.
- Short data retention. Standard retention is just 3 months (13 months with Pro Pack).
- No role-based access. Everyone sees the same data. There’s no clean way to give users a view that’s scoped to their responsibility.
- No drill-down. Dashboards are static. When a metric looks off, you can’t click into it to investigate.
- Limited call queue reporting. Webex provides essentially one primary call queue report, built for high-level summaries.
- Slow report generation. Reports routinely take 10–15 minutes to generate, sometimes longer.
- No report preview. You can’t validate field selections before running a report. Building a useful report becomes trial-and-error — run, wait 10 minutes, adjust, repeat.
- Rigid, predefined reports. Detail reports can’t be easily tailored to specific use cases. Customization options are narrow, and non-technical users need training to get value out of it.
- No cradle-to-grave call journey visibility. You can’t follow a single call end-to-end across auto attendants, queues, transfers, and final outcome.
- No hybrid visibility during migration. Control Hub can’t combine Webex Calling data with CUCM data, creating a reporting gap in mixed environments.
- No proactive alerting. No notifications for 911 calls, threshold breaches, or anomalous patterns.
ISI Analytics: Enterprise-Grade Reporting for Webex Calling
Extended Data Retention
Keep call data for 13+ months — compared to Control Hub's 3-month standard. Meet compliance requirements without needing the Pro Pack premium, and enable meaningful year-over-year trend analysis. ISI offers unlimited data retention options for organizations with long-term regulatory needs.
Cradle-to-Grave Call Journey Tracking
See the complete path of every call — from auto attendant entry through queue routing, transfers, holds, and final disposition. Identify exactly where callers drop off, spot problematic routing patterns, and measure the full caller experience end-to-end. This visibility simply doesn't exist in native Control Hub reporting.
Hybrid & Multi-Platform Reporting During Migration
ISI is the only analytics platform that lets you report on CUCM and Webex Calling simultaneously — critical during phased migrations. Maintain a single pane of glass across mixed environments, with no reporting gaps as you transition users and devices. Post-migration, ISI seamlessly shifts to Webex Calling as your primary data source. ISI also supports Microsoft Teams and Avaya, so your reporting consolidation extends across your entire UC estate.
Routing Events vs. Performance Metrics
Webex Control Hub reports on routing events — transfers, forwards, conferences, hold actions. Technically accurate, but it forces every manager and supervisor to reconstruct what actually happened on each call and decide whether the result was good or bad.
ISI translates those same events into the performance metrics operations teams already measure on: answered calls, abandoned calls, wait time, service level, and call handling outcomes. The data is structured, immediately interpretable, and aligned with how organizations actually evaluate performance.
Webex shows you activity. ISI delivers answers.
What Else You Get with ISI Analytics for Webex Calling
Webex Customer Experience Integration
Enhance CX Basic and CX Essentials reporting. Extend agent productivity metrics beyond native dashboards with a unified view across Voice Queues and call queue analytics.
Intuitive, Role-Based Dashboards
Purpose-built views for agents, supervisors, department managers, and executives — each scoped to what they're responsible for. No training required, with customizable widgets and report templates.
Drill Down From Any Metric

Reports That Run in Seconds, Including Live Preview
Skip the 10–15 minute Control Hub wait. ISI reports return in seconds, and the report builder previews fields and filters before you run, so you can validate the output without trial-and-error rebuilds.
