Background
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.
