The VoIP Gateway allows to interconnect the IP telephony world, with the conventional telephony networks, particularly with PSTN (Public Switched Telephone Network), ISDN (Integrated Services Digital Network), GSM and trunking networks.

It also works as a Call Center, allowing a group of IP-operators deal with calls from different places at the same time and manage multiconferences, diffusions, wire tipping and more functionalities.

All the conversations can also be recorder in a hard disk with 'wav' format.
