Why does my landline crackle?
The most basic method is provided as a set of switches or a scrolling dial at the side of the handset. More recent telephones will offer a digital alternative, where you can select the exact level of volume from your cordless phone or wired base unit.
Using a cordless phone means that you’re able to make phone calls in any part of the house, and you’re never restricted by the wiring that you’d need to take into consideration on a wired telephone. It tends to be the case that a cordless phone is more advanced than a traditional wired phone, but one problem that can arise from owning a cordless phone is that a poor signal between the phone and the base unit can cause unwanted noises.
If you plug another phone into the wiring of the phone you’re having problems with, you should be able to establish whether the fault is caused by your handset or the wiring in your home. There may be an issue with the connection coming from your local exchange or the signal being sent from your landline provider. If you check with other homes in the area and your landline provider, you should be able to rule out these two possibilities.
More often than not, the reason for a crackling noise in your cordless phone is due to interference from other electronic devices or a poor signal between your phone and the base unit. If you’re using more than one cordless phone in your household, it could even be the case that they’re interfering with each other despite often being the same make and model.
