Chapter 1: Overview
Tenor AXE Enterprise VoIP Gateway (AXE0800, AXE1600, AXE2400) Configuration
The AXE Enterprise VoIP Gateway is mainly intended for applications interfacing between the PBX
and the VoIP network, but it also includes two FXO ports for autoswitching PSTN back-up and 911
service provision. The number of VoIP ports is equal to the number of FXS ports. Calls can be
routed in any direction between any of the ports.
See Figure 1-9 for an example of a call originating from a PBX.
