Tenor AX Call Paths
Tenor AXM MultiPath Switch (AXM800, AXM1600, AXM2400) Configuration
The Tenor AX VoIP MultiPath Switch Configuration is symmetrical with an equal number of
Phone/FXS and Line/FXO ports. Calls are routed from the Phone/FXS, Line/FXO, or IP Network.
Calls can be routed in any direction between any of the ports.
Below are descriptions of the basic call paths from the FXS (Phone), FXO (Line) and IP; the exact
call path will be determined by the specific Tenor AX configuration you have in your network.
FXS (Phone) Originated Calls. Calls coming from the Phone/FXS interface (i.e.PBX) may be
switched to either the data network as a VoIP call or to the FXO interface, typically for connection to
another circuit switched network such as the PSTN. The routing decision made by the Tenor AX is
based upon your configuration and the dialed number. See

FXO (Line) Originated Calls. A call coming from a Line/FXO interface may be switched to either
the data network as a VoIP call, a Line Circuit, or trunk typically for connection to a termination
device on the user's premises such as a PBX. The routing decision made by the Tenor AX is based
upon your configuration and the dialed number. See
