The following review was conducted in February 2017.
VTech is a relative newcomer to the SIP business phone scene. They’ve had a long history of making wireless phones, so their release of a wireless DECT SIP phone seemed like a bit of a gimme.
We were lucky enough to be sent several VTech models, including the the VSP600 ErisTerminal® SIP DECT base station, as well as VSP601 cordless headsets and a VSP608 cordless deskset. The VSP608 is interesting, because it only needs a power connection to operate, and not an Ethernet connection.
