I have not purchased a retail OBi110 unit myself, I'm guessing it came with a power adaptor, a single RJ11 to RJ11 cable and the OBi110 adator itself?Trustever wrote:the DECT Phone links to the OBI using the cable included in the box, the OBI using the Telco Port connect to the wall socket using a Generic RJ11 (M) to BT (M) Socket Cable
If so, the cable supplied with the OBi110 an RJ11 to RJ11 is not for connecting a phone to the OBi110, it's supplied to connect the OBi110 to a US PSTN line. Annoying for us UK customers!
You need to use the cable supplied with your DECT phone and plug it into the adaptor I linked to above, this in turn plugs into the back of the OBi110 phone port. It contains a ring capacitor that is required here in the UK to make the phone ring.
The RJ11 to RJ11 connects to the telco port and you need a RJ11 to BT adaptor to connect it to the BT PSTN line as shown here: http://www.dcdi.co.uk/product/356/adapt ... wwodkLoAhQ
