* Microsoft Teams Phone requires a base Microsoft 365 subscription (Business Basic $6/user/mo or higher) — not included in these figures. Teams Phone Standard has no PSTN minutes; pair with a Calling Plan or Operator Connect. Common area phones require a Teams Shared Devices license (~$2.50/user/mo) plus Phone Standard.
* RingCentral, 8x8, Zoom Phone, Cisco Webex, and Dialpad include PSTN calling in their base plans. Common area estimates use the same per-user rate as a proxy — actual CA licensing varies by provider.
* International calling estimates reflect the lowest available add-on or plan upgrade. Per-minute rates vary by destination. Request formal quotes for specific country requirements.
* Volume discounts (typically 10–35%) are available at 100+ users on most platforms. Month-to-month rates are approximately 20–33% higher than annual.
