Claims
| # | Claim | Status | Confidence | Verified |
|---|---|---|---|---|
| 1 | An estate standardised on Cisco 6800 series phones running Enterprise firmware faces hardware replacement rather than firmware conversion, so a migration business case built only on licence costs will understate the true cost. Transitioning from Unified CM to Webex Calling — Deployment Guide · Derived from Inventory existing devices and clients, Desk Phones | inference | 0.60 | 2026-09-04 |
| 2 | Cisco 6800 series IP phones cannot be upgraded from Enterprise firmware to Multiplatform firmware, so a 6800 running Enterprise firmware on Unified CM must be replaced rather than converted. Transitioning from Unified CM to Webex Calling — Deployment Guide · Inventory existing devices and clients, Desk Phones | fact | 0.90 | 2026-09-04 |
| 3 | Cisco 7800 and 8800 series phones must be converted from Enterprise firmware to Multiplatform firmware before they can register to Webex Calling. | fact | 0.90 | 2026-09-04 |
| 4 | Older 8800 series units with hardware version VID 14 or earlier will register with Webex Calling but may show performance issues arising from hardware limitations. Transitioning from Unified CM to Webex Calling — Deployment Guide · Note, Desk Phones | fact | 0.90 | 2026-09-04 |
