4.2.4.2. Configuring the PSTN (FXO) Gateway
This method allows you to enable a user to make IP-to-PSTN voice calls without
using a VoIP service provider or their gateways. The architecture is based on a
'personal' IP-to-PSTN gateway (PIPG) deployed at the residence or business of a
user, where both PSTN and Internet service are assumed to exist. This method
enables the bridging of a voice call between an Internet endpoint, such as a soft
phone, and a user's PSTN line.
Here Line can be configured with a regular VoIP account and can be used in the
same way as the Phone 1 of any CRA Model. This VoIP account can be configured
to support PSTN gateway calls exclusively.
