configuring IPX-600 to do the PSTN call:
a. Configure the FXO gateway to register to IPX-600. If the FXO gateway registered to IPX-600
with the registered number as 0, then, any extension IP Phone can dial 0# to first connect to
the gateway, and then dial the desired PSTN number. This is a two-stage dialing.
b. If you want to configure a one-stage dialing, a call route with destination IP address pointed to
the FXO gateway must be added in the “
Call Route
” list. The following figure shows the
example configuration. In this way, the FXO gateway does not need to register to IPX-600.
