PPTP
Point-to-Point Tunnelling Protocol (PPTP) is a network protocol
that enables the secure transfer of data from a remote client to
a private enterprise server by creating a virtual private network
(VPN) across TCP/IP-based data networks. PPTP supports
on-demand, multi-protocol, virtual private networking over
public networks, such as the Internet. This IP Phone has
built-in PPTP Client which allows connection to a PPTP based
Virtual Private Network (VPN), such as VPN Broadband Router
or IP-PBX with PPTP function built-in.
