How the ZIRO Platform Simplifies Cisco CUCM to Teams Phone Migration

Why Everyone’s Moving Away from PBX Systems?

PBX systems have been the backbone of enterprise telephony for decades. However, in 2025, for a growing number of businesses, these systems have become a liability.  

And for all the right reasons as: 

• They’re expensive to maintain, with ongoing carrier contracts and aging hardware 
• Support is complex and slow, requiring senior IT engineers to handle even basic tasks 
• They lack mobility and flexibility, making it harder to support hybrid workforces 

Therefore, this migration is the right, wise, and strategic next step. 

Migration Is Risky, Error-Prone, and Takes Too Much Time 

This is what we hear all the time. 

The truth is, most migrations fail, take way longer than expected, or consume more budget than was allocated because they rely on manual processes to: 

•  Assign and validate licenses 
• Apply the correct voice policies 
• Configure dial plans 
• Provision and activate phone numbers  

Doing all this manually isn’t just inefficient. It’s where the errors happen. 

And more often than not, it demands PowerShell skills or deep familiarity with Microsoft Teams Admin Center. Skills that most helpdesk staff or voice admins aren’t expected to have. 

You’re not alone in this. Every IT team faces the same challenge. 

But here’s the thing: you have a choice. You can keep doing what everyone else is doing and hope for the best. Or you can work smarter by choosing a platform that automates the entire migration process for you.  

How Can I Automate Microsoft Teams Phone Migration Without PowerShell? 

The answer lies in ZIRO’s automation platform.  

It automates 80% of the migration process, and most teams are able to complete the voice migration from PBX to Teams Phone in under weeks.  

Which features help ZIRO’s clients speed up the voice migration process? 

Based on countless enterprise migrations, these are the features that consistently save time and eliminate errors. 

• Automatic categorization of phone numbers by type, eliminating tedious manual sorting 
• Intelligent migration of E.164 numbers, ensuring global consistency without regex headaches 
• Automated translation of CUCM Hunt Lists, compressing weeks of dial plan work into minutes 

Which Day 2 Migration Features does ZIRO Platform Provide?  

A successful migration is only half the story.  

The real challenge starts on Day 2, when Teams Phone management shifts to your IT operations and helpdesk.  

Without the right automation, most organizations slip back into manual processes that cause errors and system drift over time. 

ZIRO Platform was designed to prevent exactly that, with features such as: 

• Automated MACDs so routine changes don’t require senior engineers or PowerShell 
• License governance tools to ensure entitlements stay aligned and compliant 
• Number management and tracking to simplify DID assignment and reallocation 
• Policy enforcement and reporting for misconfigured policies so  

Issues can be resolved before they affect users 

With these features, Teams Phone remains easy to manage and stable long after cutover.  

Does ZIRO Provide Customer Support?

For organizations that want more than just the platform, ZIRO also offers managed services to take the pressure off IT teams. These services include:

• Incident management for Teams Phone 
• Call utilization analytics and adoption insights 
• Endpoint support and problem management 
• MACD support on demand (for organizations that prefer ZIRO to handle changes directly) 

With tiered service options (Basic, Plus, Premium), you can scale coverage as your needs change. And because ZIRO’s managed services come with zero lock-in, you’re free to scale up or down anytime without rigid contracts.
