Quotable quotes
This problem generally happens when the Land line phone wire is in
contact with the other phone wires. May be, sometimes, our neighbour
is having a phone line connected to the same junction box or it is in
close contact with any other wire while on its route to the Exchange,
which is unavoidable, but can be rectified if contacted through the Exchange,
may be with some personal attention. There is one more thing to detect
is owing to network connection also. Other solution could be Cordless
phone, which would be more ideal. I understand there is a latest feature
of "do not disturb mode". It can also be explored.
