Network requirements
Router A and Router B are both connected to an IP network and a PSTN.
■
Telephone A attached to Router A can make calls to Telephone B attached to
Router B over the IP network or the PSTN.
Usually, Telephone A makes calls to Telephone B over the IP network. In the
■
case that the IP network is unavailable, Telephone A selects the PSTN via the
bound FXO voice subscriber line to call Telephone B.

Configuration idea
There is one-to-one binding between FXS and FXO voice subscriber lines.
■
When the IP network is available, the VoIP entity is preferably used to make
■
calls over the IP network.
When the IP network is unavailable, the POTS entity is used to make calls via
■
the bound FXO voice subscriber line.
Configuration procedure
Router A and Router B are both reachable
■
The configuration of interface IP addresses is omitted.
