    Phone systems of the world are different. if in the US, some phones won't work 100% if the polarity is reversed. .uk systems are just plain weird.

    There can be cabling problems that can affect incoming ringing. High line resistance, corroded connections etc.

    The usual test, is to test with a known good phone. In the US, we can disconnect the premise wiring and test at the NID (Network Interface Device).

    Thank you for both you on your replies. At first, the telephone was working quite well. It rings on all incoming call. But after some days it stops working. There may be fault in ringer circuit because I also observe that neither it rings nor its new call indicator flashes on incoming call while rest is ok.

    As already mentioned, without telling us your location we can't really offer advice.

    Is this a private, semi private or multi party telephone line?

    Maybe the ringing detector part of its circuit got zapped?
    Did the weather produce lightning between when it worked and when it stopped working?
