The Orchid V4 low cost router (LCR) sits between your telephone and the phone socket. Once programmed, the Orchid V4 will route your outgoing calls via low cost phone companies such as 18185.co.uk, saving you money on local, national and especially international calls. You’ll need to understand a bit about programming the Orchid V4 but it can all be done from your phone. Instructions included. Powered from the phone line or you can add an optional (not included) 6v power supply. These units aren’t made anymore but still do what they were designed for - saving you loadsa ££££ on phone calls. I have four of these - message if you want more than one.
