It's not just your phones
Most businesses have lines that quietly run something important. These are the ones that catch people out.
One clear plan, in plain English
- A register of every line and what is connected to it
- A risk rating for each line, life-safety items first
- A migration plan in priority order
- Indicative costs for equipment and installation
- The questions to ask your phone provider, alarm company and lift maintainer
