Sometimes we receive calls and sometimes we don't. Sometimes it rings once, sometimes three times then stops.
I can make outgoing calls but not always receive calls. Callers report that when they ring the phone either continues to sound as though our phone is working but isn't answered and doesn't go onto our answerphone. Alternatively, they report they just get a noisy crackle.
We don't know whether the fault is with our phone or with the line. Hopefully someone has some suggestions as to how we resolve the problem.
