VoIP hardware is developing fast - this is where you ask all those “how do I make my SIP Telephone, Adapter or Asterisk box work with my voip provider?” questions.

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?

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

The box contained apart from the eternet cable to connect to the router and the power plug

1.a cable RJ11 (M) to RJ11 (M) that I have used to connect the OBi110 to the base of the DECT Phone
2. a cable very RJ11 (M) to US PSTN that I have no use for

and I have purchase separately this cable that goes from the Telco Line port on the OBi 110 to the BT wall socket

What I wonder is could I have used the some old cable that initially connected the DECT Phone to the BT Wall Socket to plug in the OBI Telco Line port ?
