Postpaid and prepaid subscribers are both served in one VPN context.
Main purpose of VPN is to manage telephone costs for companies. VPN offers near to 100 features of which private numbering plan, call diversion, outgoing call screening, personal/business calls, unique number and hunting are only a few examples.
VPN supports integration to different type of access networks which enables VPN functionality to mobile, PBX and VoLTE users.
