We have a VoIP PBX that we and our associates use for internal conversations,
and it uses one of our several VPNs, which makes the conversations totally private.
It also makes it possible for us to call (or be called) via an Internet connection anywhere in the world, without incurring cellular or toll-call charges.
The phones themselves can be either physical desktop ones or software ones such as Linphone./>

We have designed and provided wireless backup and wireless Internet access solutions spanning many kilometres,
and have delivered wireless networking to conferences of hundreds of people.
E.g. We were the technical design consultant for a multi-relay 5.8 GHz wireless link to provide fast Internet access to the residents of an isolated NZ South Island valley. No surprise that it worked first-time.
The main use of the 6.5 km link shown was for doing frequent back-ups of a client's server to a machine in our CBD office. It was needed because only ADSL-based internet access was available where the server was located. The maximum ADSL upload speed is 2 Mbit/s and the 5.8 GHz wireless link provided 130 Mbit/s.
For one 200 metre WiFi link there wasn't direct RLOS (radio line-of-sight) but a metal roof near the midpont worked more than well-enough as a reflector.
