Technology of Location Hiding by Spoofing the Mobile Operator IP Address

This paper discusses the issues of hiding geolocation when sending messages on social networks, holding teleconferences, and sending emails. Single-board computers were used to form the experimental setup. One was equipped with an access point and a SIP server, and the other was running a SIP client. The system was tested with different audio codecs. We also checked the substitution of geo-location when working in social networks. In addition, the issues of choosing the optimal codec for SIP clients and the key length are considered.
