two separate ring tones.
No ring tone is sent to the called phone. In olden days it needed to be generated inside the master socket when an incoming call was received, and sent to the physical phone down the ring/bell wire. All Openreach current master sockets still generate it.
Most modern phones and dangly filters generate it themselves if it doesn't come down a ring wire, which is why we always recommend disconnecting the ring/bell wire at the master socket on xDSL installations. It acts as an aerial and feeds electromagnetic noise back onto the line, messing up the xDSL.
As I said, when you call a faulty line you will normally still get your ring tone. But if the call does not reach the master or phone because of the fault then there will be no ring tone at the far end. It is the call voltage that triggers the ring tone at the receiving end - the ring tone does not exist as part of the call.
The fault in this case was that a different number had been put on the line, which is where the thread started from. Of course your son could call out, and of course you calling the expected number didn't work. But the number you called was still associated with the physical line in the database so was recognised by the system when you called it and got the ring tone.
As soon as that number was re-ported onto the physical connection all worked fine.
Something went wrong. We know that, you know that. You posted:-
Thank you for that, but the question was "what has happened here"- why was the number changed with no notice?
He tells me that as of 11:30 he is 'back' on the correct number
You have had many explanations. All basically along the same lines but with minor variations.
It's life. It happens. It might have been a routine step, or it might have been a clanger dropped by someone. Are you perfect and never made a mistake that affected someone else?
Talk of breach of contract is simply laughable, and wild derogatory remarks about Openreach engineers in general completely out of order. Criticising Openreach itself if appropriate is another matter, or a specific engineer who you know was responsible for poor work (and not simply doing as ordered by management) would be another matter.
Kindness isn't going to cure the world of all its awfulness but it's a good place to begin. Daisy Ridley.
