IP PBXs promises true convergence
between headquarters and remote offices with one network.
What about integrating those assorted telephony
devices, such as fax machines, analog phones, cordless
phones, intercoms, paging systems, and even legacy
PBXs into the IP based phone system? The branch office
may require local connectivity to the PSTN for
local off-net calls and 911.
The Tenor VoIP MultiPath Switch combines FXS ports and FXO ports with
Intelligent Call Routing to offer 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 within a total IP PBX environment or where
existing traditional PBXs need to be integrated into
the IP network.
