This paper presents the methodology and results of an experimental estimation of the channel width required to transfer traffic from VoIP subscribers connected via VPN technology to IP ATC Asterisk. OpenVPN technology with typical settings (tun interfaces, routed network segments and TCP transport protocol) was used. An updated tool for estimating the volumes of transmitted and received traffic was used, based on data processing from the ipcad sensor — an emulator of the Cisco NetFlow mechanism for linux routers. The operator representation of extracting information about single network sessions is used.
