Chapter 1: Overview
IP Network Calls. Calls coming from the IP network data can be routed to the Line/FXO or Phone/
FXS interfaces. The Tenor will route calls based upon the dialed number. If the number is config-
ured as a local phone number, the call will be sent to a Phone/FXS circuit for termination, otherwise
the call is considered a “Hop-Off call” and the Tenor sends it out through a Line/FXO interface, typ-
ically connected to the PSTN. See Figure 1-6 for an example of a call originated from the IP net-
work.
