Landline Not Working

Just moved over to vodafone and they are supposed to have ported my landline number over, however, my number is not working and there is no obvious way to contact anyone to get it resolved.

Not a great start for a new customer.

Thanks Jayach, I think you have identified the problem. The DECT base uses the middle 2 pins of the 6 available (say 3 and 4); the VF supplied DSL cable uses 2 and 5. So they are making no connection at all! I will investigate the solution you suggest.

(This must be a widespread issue I woul think!)

Looks like I can buy a DSL cable with 4-pin RJ11 connectors at both ends. Do you think that would do it?

Personally I would so no. The wiring will still not match.

Why can you not use a "VoIP adapter", as I suggested. Were you not supplied with one?

As all new installs use digital voice. there should be one supplied.

If you haven't got one ask on live chat. https://www.vodafone.co.uk/bbservcd

The adapter should include a ring capacitor which is required by some phones, the cable won't. IMG_20220329_011218.jpg

Where did you get the info that a DSL cable can be used, it used to say that on the diagram on the box, but I thought it had changed.

No, I didn't get an adaptor. The guy who did the fibre installation told me to use the DSL cable supplied, but he left before the broadband service was activated so wasn't there to check anything worked. I will ask for an adaptor. 

(I agree a 4-wire cable probably won't work)

Yet a 4 wire modem lead worked fine for me 🤔

The THG3000 TEL sockets only have 2 physical connector pins, unless those pins connect to the correct 2 pins in the DECT base (polarity isn't important) it won't work. 

I suspect some DECT bases that have 4 physical pins have the pins paired so they will match up either way. (probably didn't explain that very well, but I know what I was trying to say)

Another thought. If a cable is described as a 4 wire DSL cable, as DSL only uses 2 wires would the pairs in the cable be shorted out so that it would work irrespective of the actual pair used in the socket?

i.e. a 4 wire DSL cable is not the same as a 4 wire RJ11 cable.

Or am I overthinking it?

The one I'm looking at on Amazon says it is 4-wire straight through:

ASNQ High Speed Broadband RJ11 to RJ11 Cable for Landline Telephone, Router, Modem to RJ11 Phone Socket or Microfilter - ADSL Cable 2m with OFC Wires and PVC Cover - Internet DSL Cable - Flat White 2m https://amzn.eu/d/8cfixhL

If you're shopping on Amazon, you may as well get the adapter from there:

That would not be compliant. The inner and outer pairs should always be seperate. 

Are vodafone only supplying single pair cables these days?
