Three reasons why Microsoft's native phone system fails enterprise businesses
Microsoft 365 doesn't include calling.
Microsoft charges an additional $8–12 per user per month just to make
phone calls inside Teams. For 100 users, that's $9,600–$14,400 every year—on top of the M365 subscription you're already paying.
There's a better way.
Microsoft's admin experience is fragmented across Teams Admin Center, M365 Admin Center, Azure Portal, and PowerShell scripts.
Building a call flow requires coding knowledge. Managing desk phones requires hunting across four portals.
When issues arise, you wait on support tickets. Your IT team deserves a real tool.
Microsoft Teams has experienced 112+ documented outages since August 2023—one significant disruption every 4–5 days on average.
When Teams goes down, every business running Microsoft Teams Phone goes dark.
• January 2024: 7-hour outage
• November 2024: 2-day outage
• June 2025: 12–18 hour global disruption
PanTerra Teams App is purpose-built for businesses that want to consolidate communications inside Microsoft Teams without inheriting a single point of failure. Your team uses one familiar interface. Your IT team manages one unified admin portal. And when Microsoft has an outage, your customers never know.
