Thanks in advance for any advice 🙂
Have you checked the landline for dial tone and ok then check for line noise
Have just done the quiet line test using a spare corded phone. Everything is silent. No crackles or popping noises.
BT checked my line after BT speed test showed ‘Slow Connection’. They’ve said that there is a fault on the network and an engineer has been booked for tomorrow to try to rectify the problem.
