Companies with multiple offices typically
maintain separate long distance services for each location.
The best way to perform this long distance consolidation
is by routing voice calls from remote offices to the
headquarter's low-cost LD trunks over existing IP data
links. This allows the calls to be routed without incremental
costs that would cut into the savings achieved through
consolidation. The use of VoIP also allows calls between
offices to bypass the PSTN – making them virtually free.
Quintum’s Tenor VoIP MultiPath Switch provides the complete
solution for implementing such VoIP-based long distance
consolidation.
