999 mystery...?
A mystery to me at least......Police received a 999 call from the next door neighbours land line telephone last night.....the thing is the property is empty....8-o
No sign of a break in. Could it be "spoofed"? Lawrence. |

More likely 112. Lose wiring shorting out in the breeze, (pulse dialling) or even a rodent nibbling through a cable.
One of the reasons 999 was chosen was to avoid this, so 112 was asking for more false calls, and it is an acknowledged problem. |
Re: 999 mystery...?
The CLI could have been spoofed as is the case with most scam calls. Or it could have been a 112 call generated as a result of a line fault. The proverbial "JCB through a cable" could generate hundreds of these calls. The cure IIRC was to run a timer after the digit 2 was received and if further digits arrived before the timer expired the call was assumed to be false and released. 112 would be fine in an all tone dialling environment, but I believe it was a condition of BT's licence that they continued to support loop disconnect dialling, something vintage telephone users are grateful for!
Emergency calls used to be "manually held" which meant that the call could not be cleared until it was released by the operator, so police arriving at the premises could speak over the connection and confirm where the call came from. There was no CLI in those days so the operator would ask the caller for their number. A second operator would then dial that number and confirm the line was busy. They'd then used the "Trunk Offer" or TKO facility to listen in on the call. TKO's original use was to enable the operator to offer a trunk call to a busy line. |
Re: 999 mystery...?
Thanks for the reply, never heard of 112 before so that explanation is a possibility.
EDIT: Post crossed. Lawrence. |
Re: 999 mystery...?
I understand that a lot of people in the UK attempt to call 911 in an emergency. They've probably watched too many American police dramas on TV.
112 is part of the GSM spec, but is also applied to landlines in the EU. No political discussion about that please. |
Re: 999 mystery...?
Just to say that 999 was an assumption on my part, a Police Officer turned up at our house this morning saying that they had received an emergency call that had been traced to next door's landline last night and had I heard anything or did I have an entrance key for that property, to which I replied no and also informed them that the last time I had seen our next door neighbour was when they took him away in an ambulance which would have been before all the virus lockdown stuff kicked in.

Like others I would suspect wind or rodents may be the cause, by shorting the wires 3 or 4 times in quick succession. John. |

And didn't they interrupt your call to tell you to contact the hospital where your loved one is dangerously ill? I thought it was still the case that the caller can not clear down a 999/112 call. |
Re: 999 mystery...?
It's difficult to imagine why anybody would go to the trouble of spoofing the caller ID in these circumstances. If someone wants to make an anonymous nuisance emergency call there are much easier ways of doing it.

Re: 999 mystery...?
Calls in the UK are generally controlled by the calling party, it is they who can clear the call. To avoid a Called Sub Held (CSH) condition where the called party clears, but the caller doesn't, such a call was force released after six minutes. This timer has been drastically reduced to prevent fraud.
Calls to operators are under the control of the operator and until the operator clears you won't get away. Originally called "manual hold". |
Re: 999 mystery...?
I was going to work one morning as a passenger with my locked mobile in my pocket when I heard voices from it! Picked it out my pocket and I was talking to the emergency services! They suggested that I locked my phone while it was being carried but didn't believe they had been rang from a locked phone!

Re: 999 mystery...?
It's also possible that the telephone companies records are wrong. It does happen. We had the police arrive at our house, saying they had received an emergency call, but no-one spoke. They were quite insistent that we had called them, from our number. We hadn't. Only when they quoted the number, which wasn't ours, did we realise what the issue must have been.
We never found out how the error occurred, but suspect that NTL had allocated the number to us when we were going to switch to them, but never updated their records after we cancelled because they were worse than useless at everything. |

Re: 999 mystery...?
If you're referring to phone tapping, TKO wasn't used for that.
Back on topic please. |
Re: 999 mystery...?
Just for the record, no, in any organised or authorised sense, that's not what I was referring to.

Time to pull the plug on this thread.
