Every Line Type We Classify
We identify what device each phone number connects to — not just "unknown line #4".
Most buildings overpay by $40-80/line/month
POTS lines average $85/month. Cellular replacers like Ooma AirDial run $35-45/month.
For a 20-line building, that's $800-$1,000/month in savings.
