IP PBXs promise true convergence ... headquarters and remote offices on one network. But, what about integrating those assorted telephony devices, such as fax machines, analog phones, cordless phones, intercoms and paging systems, and even legacy PBXs, into the IP-based phone system? The branch office will also require local connectivity to the PSTN for local off-net calls and 911.

The Tenor VoIP MultiPath Switch, with its combination of FXS ports and FXO ports with intelligent call routing, offers the complete branch office solution. The Tenor also provides survivability for the branch office, assuring that the office is never without phone service. The Tenor can be configured to operate with an all-IP PBX environment, or where existing traditional PBXs need to be integrated into the IP network.
