If the carrier-issued telephone number is in the relational database, this indicates that the carrier-issued telephone number is registered for trixNet service. Since both the caller and call recipient are using trixNet registered network devices (e.g., via their registered carrier-issued telephone numbers), the call may be established for free over a (trixNet) carrier-independent network. As such, a peer-to-peer connection may be requested in step 810. In exemplary embodiments, the mapped address is determined. The address may then be returned to the call management system 112, which requests establishment of the peer-to-peer connection.

The peer-to-peer connection between the two addresses (of the caller and call recipient) may be tested in step 812 in order to ensure availability and quality. In one embodiment, the system monitoring module 212 of the data center system 104 may check the quality and availability of the IP network 106. In other embodiments, the fallback module 316 of the call management system 112 may check the quality or availability of the IP network 106.

If in step 814, the peer-to-peer connection exceeds the acceptable specification established by user (or their administrator), then the VoIP call may be established in step 816. However, if the acceptable specifications are not exceeded, then the call is routed via the standard third-party route chosen by the user (or their administrator) in step 808.
