What This Quantified Business Impact Looks Like

Cost Savings from Replacing Legacy Phone Solutions

The most immediate ROI driver comes from eliminating expensive traditional telephony infrastructure. You can achieve substantial savings by consolidating multiple vendor relationships and deprecating hardware-intensive systems.

Enterprise Cost Elimination:

  • Hardware savings: Eliminate PBX equipment, reducing power and cooling costs by up to 90%
  • Licensing consolidation: Replace multiple telephony vendors with unified Microsoft 365 licensing
  • Usage cost reduction: Significantly reduce long-distance charges and international calling fees
  • Infrastructure footprint: One telecommunications company reduced telephony infrastructure by 90% in data centers

SMB Cost Optimization:

  • PBX replacement: Avoid $30,000 one-time hardware replacement costs
  • Mobile reimbursement reduction: Cut monthly mobile costs from $50 to $5 per user for non-mobile employees
  • Simplified billing: Single vendor relationship vs. multiple telecom providers

Real-World Example: ScottMadden consulting firm achieved $90,000 annual savings ($7,500 monthly) after implementing Teams Phone, while enhancing data security through Microsoft E5 licensing integration.

Reduced IT Management Burden

Teams Phone dramatically simplifies telephony administration by integrating with existing Microsoft 365 management workflows, eliminating specialized skills requirements and reducing support overhead.

Enterprise IT Efficiency:

  • Unified administration: Single Microsoft 365 Admin Center for all communications

  • Reduced vendor management: Eliminate multiple telecom provider relationships

One financial services company noted: “The benefits around being able to manage the security all within the Microsoft Teams and 365 platform. Being able to keep it all within one platform has been beneficial from the legal and client standpoint.”

Enhanced User Productivity and Collaboration

Teams Phone integration eliminates communication friction, enabling seamless transitions between voice calls, video meetings, chat, and file sharing within a unified platform.

Quantified Time Savings:

  • Highly mobile users: Save 1.6 hours per week on average
  • Standard users: Save 15 minutes per week on average
  • Productivity recapture: 50% of saved time is repurposed productively

Workflow Integration Benefits:

  • Click-to-call functionality: Direct calling from any Teams interface
  • Seamless device switching: Transfer calls between desktop, mobile, and desk phones
  • Integrated presence: Automatic status updates across all communication channels
  • Unified history: Single location for all communication records

Teams Phone vs. Traditional PBX: TCO Analysis

The total cost of ownership comparison reveals significant advantages for Teams Phone across multiple cost categories.

Traditional PBX Annual Costs:

  • Hardware purchase/lease: $28 per user per month
  • Maintenance contracts: Substantial ongoing expenses
  • Long-distance/international: $10 per user per month
  • Specialized IT management: 3 FTEs @ $150,000 annual salary

Teams Phone Annual Costs:
