The legacy phone models are deprecated for the following reasons:

  • Security—since legacy phone models are not updated with critical software fixes, we have limited ability to protect customers when security issues arise.
  • New feature implementation—legacy phone usage slows down implementation of newer features.
  • Sustaining—no development support or regression testing is currently being done for these older phones.


Products Affected Version
Cisco Unified Communications Manager 11.5(x)
Cisco Business Edition 6000 11.5(x)
