The Ooma AirDial POTS line solution routes communications over network paths that are proactively maintained by managed facilities-based voice network (MFVN) compliant providers. MFVN is a network owned and operated by a voice service provider that delivers traditional telephone service via a loop start analog telephone interface.

Outbound Ooma AirDial traffic is first routed over T-Mobile’s MFVN-compliant LTE cellular data connection. T-Mobile and Ooma AirDial has partnered closely to create a direct ethernet connection to the Ooma MFVN network in a shared data center.

From the data center, traffic is passed to an MFVN-compliant gateway provider with a direct hardwired connection in a shared data center. Our gateway partner then terminates the call to the Public Switched Telephone Network (PSTN).

This set of direct connections is designed so Ooma AirDial communications will not traverse the public internet.

This is a critical feature of the Ooma AirDial architecture that is different from many VoIP solutions of which traffic is handed off to the public internet for one or more legs of the path.
