  Analog Voice Over IP Gateway
The objective of the 'Analog VoIP Gateway' project is to enable the standard telephony equipment connected to FXS (POTS), FXO (PBX connection) and E&M (Trunk connection) interfaces to be bridged with the remote equipment using the Internet. With this, we will be able to provide a gateway between the PSTN networks and the Internet.
