Possible example of usage
In this case, the vSPi allows you from anywhere (home office)
use a hardware VoIP phone connected directly to the PBX
or computer via a secure encrypted VPN connection.
Based on this you will be able to use all functons and features
whether branch office exchanges without restrictions,
including call recording as well as others application
or data services available from a computer.
Of course for a VPN connection via vSPi
you do not need to have a static (public) IP address.
