I do not understand yet to voip, only conventional telephony. I want to install 2 or more extensions for analog lines, right on LAN network. They would be connected in an ATA (or other) and the LAN. By be used to receive or make calls, the conversation would be recorded in the designated computer (which will not make or receive calls, only record). It is possible? What hardware and software to be used (VRS / Axon)? CAATI
