Telephone problem with Caller Display - ADSL filter related

A few days ago the Caller Display feature ceased working on my phone line - I tracked down the cause of the problem to the ADSL filter that's built into the faceplate on my master socket.

This is the type of faceplate that I have:

http://www.ebay.co.uk/itm/221287926906?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2648

With the faulty faceplate in place the phone would no longer display the incoming phone number - I unplugged the faceplate and plugged a separate ADSL Filter into the master socket and all was well - the incoming phone numbers were displaying again.

Today I got a replacement faceplate (exact same type as the original pictured above) - this worked ......... but then failed a few hours later! I've now unplugged the new faceplate and plugged back in my old separate ADSL Filter for now.

So, two possibilities:

a) The new faceplate was simply faulty, or:
b) There is something wrong with my phone line (or my router or phone?) which is damaging the filter in the faceplate. But what would cause that? And why did the separate filter work fine for a few days (and is still working now?).

All I have plugged into the phone line is my single cordless phone and my router (a BT Voyager 2110).

Should I perhaps get a different type of faceplate (maybe one that's more resilient?) - if so, any recommendations please? Naturally it must be compatible with my master socket as the one above is.

Thanks!

    Not all ADSL filters are equal - read this here.

    The face plate is obviously (to me) filtering out the CLI signal. The replacement which worked probably burned in over a few hours to the point that it no longer worked. Possibly your phone line is wired with reverse polarity but that is a nearly random guess.

    I have this one http://www.telephone-wiring.co.uk/vdsl-bt-infinity-i-plate-665-p.asp which works with CLI.
    You might as well ask the Wizard of Oz to give you a big number as pay a Credit Referencing Agency for a so-called 'credit-score'
  • Thanks for that and the faceplate info, will investigate further.

    Forgot to mention, you still need the old pre ADSL lower frontplate to work with that one.
