Ooma AirDial alternative: per-line pricing versus per-device pricing
AirDial is a capable product. The question worth asking is what it costs to keep twelve analog lines alive for the next five years, and that answer comes down to how the service is priced.
The short answer
Ooma AirDial is priced per analog line plus a monthly hardware charge per unit, with each unit covering up to 4 lines. LineBridge is a fully managed solution: a published per-device hardware rate of $40 per month for up to 2 lines, $70 for an eight-line device on a wired circuit, and $90 with 5G/LTE transport, with the SIM and cellular connectivity, phone numbers and voice platform, and 24/7 monitoring and management stacked on top as one flat invoice. It is not a bare hardware lease. Both platforms keep elevator phones, fire panels, fax, and alarm dialers on real analog dial tone. The practical difference shows up as line count grows: per-line pricing keeps climbing, per-device pricing does not.

What each approach costs by line count
Monthly service only, excluding one-time setup and install charges.
| Analog lines | Ooma AirDial (indicative) | LineBridge (published) | Difference per year |
|---|---|---|---|
| 2 | $95/mo | $78/mo | $203 |
| 4 | $175/mo | $122/mo | $634 |
| 8 | $350/mo | $138/mo | $2,539 |
| 16 | $699/mo | $276/mo | $5,078 |
| 40 | $1,748/mo | $690/mo | $12,696 |
AirDial figures use rates commonly quoted by resellers in 2026 – roughly $39.95 per line per month plus $15 per month for each unit covering up to 4 lines, and reflect the full managed service. Ooma does not publish AirDial pricing, so confirm current rates directly with them. LineBridge figures are the fully managed all-in monthly rate – the device, SIM and connectivity, phone numbers, and 24/7 monitoring combined – on wired transport; sites needing 5G/LTE primary transport are $90 per device.
