Always-on Business Connectivity with Ooma AirDial

MultiPath is a patented connectivity feature in Ooma AirDial that continuously sends voice traffic over both the device’s LTE connection and the customer’s wired internet simultaneously. It constantly monitors both links and dynamically uses the best performing connection. If one link degrades or fails, the other immediately carries the traffic without dropping the call — ensuring uninterrupted service for life-safety and business critical devices.

Instead of waiting for a primary link to fail before switching, MultiPath uses active-active redundancy, so calls are never dropped when one connection experiences congestion, packet loss, or downtime. This dual-path approach offers a more reliable and seamless failover than traditional single-link methods.

Ooma AirDial includes a built-in LTE modem with support for major North American carriers. If your primary broadband connection fails, the LTE network becomes the active path for voice traffic — maintaining connectivity for critical systems like alarm panels and elevator phones.

Ooma AirDial is designed to work with LTE networks from all major operators in North America. In areas with weak coverage, Ooma can support resolution options such as alternate carriers and external antenna solutions to improve signal strength.

Ooma AirDial works with T-Mobile for Business, AT&T, Verizon, UScellular, Rogers, Bell.

In most locations, the standard LTE antennas that come with AirDial provide sufficient coverage. However, if your site has a weak cellular signal, external antennas can be deployed to enhance LTE connectivity and ensure consistent failover performance.

Absolutely. Ooma AirDial is a POTS line replacement solution, meaning it connects directly to your existing analog equipment (e.g., fire alarms, elevator emergency phones, fax machines, security systems) using RJ-11 ports — translating analog signals over digital IP or LTE networks.

AirDial includes battery backup that maintains service for up to ~16 hours, and with optional external battery accessories, this can exceed 24 hours. This backup ensures emergency communication systems stay online even when utility power is lost.

Besides MultiPath redundancy and LTE failover, AirDial supports features like remote monitoring and management, alerts for service interruptions, and extended battery backup — all designed to keep mission-critical devices operational and compliant with safety codes.

No. Because AirDial continuously transmits over both wired broadband and LTE, fluctuating conditions on one path don’t interrupt calls. The system automatically maintains the best connectivity path in real time.

Yes. MultiPath connectivity is included as part of the Ooma AirDial platform and applies to all customers to ensure uninterrupted backup and service continuity.
