Re: [VoiceOps] False 911 calls and old abandoned DID

D'oh! Guilty (and ignorant) as charged. Thank you Mike (and others) for enlightening me :) Bloody classic really - I've always know it worked that way because I used to "tap out" free calls home to Mum to pick me up when I was a lad and needed a ride home. This was before the times of

Re: [VoiceOps] False 911 calls and old abandoned DID

Thank you for indulging me and sharing this! While I fully believe this *can* happen and *has* happened I suspect it doesn’t actually happen as often as it becomes a plausible answer and then the line is fixed or disabled or it just stops happening with no known root cause or follow up. I am

No, it's really just 1-9 clicks, or 10 clicks for 0. I've got a rotary dial on the desk next to me. On 1/21/21 6:42 PM, Pete Mundy wrote: So close! But on the PoTS equipment I'm familiar with (others can chime in and correct me if I'm wrong on a larger scale) the numbers are reversed (well

My understanding was that it was chosen cause it was easy to remember (especially for kids), simple to dial, and didn’t conflict with any service or area code with no consideration for pulse shortness. -- Fred direct/sms +1 (336) 439-3733 > On Jan 21, 2021, at 6:59 PM, Carlos Alvarez wrote:

Island time is chill, yo. New Yorkers and Southern Californians got to do things like NOW! Two pulses, one pulse, three pulses would be Los Angeles. I mean, I can test dial something right here at home if you want, I have the means. Yes, it works. https://imgur.com/5m2Fe5b On Thu, Jan 21,

Re: [VoiceOps] False 911 calls and old abandoned DID

I think another possibility for the why 911 vs another random number is when you introduce dialing plans into the mix. Because of the ambiguity avoidance around 9xx, there’s probably a lot of stuff out there that runs a call without further waiting for digits once those are in the mix. Lots

Re: [VoiceOps] False 911 calls and old abandoned DID

That would be odd one of the reasons that big cities in the US got area codes like 212 was because it was shorter to dial with fewer pulses needed. Hawaii got stuck with 808 On Thu, Jan 21, 2021 at 3:43 PM Pete Mundy wrote: > > So close! But on the PoTS equipment I'm familiar with

So close! But on the PoTS equipment I'm familiar with (others can chime in and correct me if I'm wrong on a larger scale) the numbers are reversed (well for all except 5 :) Basically it counts down from 10. 1 pulse is digit '9', 4 pulses is digit '6', 10 pulses is digit '0'. So do dial 911

Re: [VoiceOps] False 911 calls and old abandoned DID

Thanks for sharing. 25+ years, most of which was hands on in the field with analog lines, PBX, low voltage cable, etc. and I never came across or heard of this happening. I fully understand how it is technically possible ( I have even demonstrated pulse dialing with a key on a 66 block with

Re: [VoiceOps] False 911 calls and old abandoned DID

Some of my equipment will show a notice, hinting at a possible issue, when "MORE THAN 10 DIAL PULSES WERE RECEIVED".  A couple years ago, the responsibility of our switching gear was being transitioned to me as the previous guy was retiring.  During that period of time, I noticed a station in

Re: [VoiceOps] [External] Re: False 911 calls and old abandoned DID

IME it's not so much that the literal digits 9, 1, 1 are pulse dialed, but some switches are configured so that a bunch of repeated on/off hook sequences will be treated as an emergency call. I think the idea is, if someone is severely incapacitated, their attempts to pick up the phone will be

Re: [VoiceOps] False 911 calls and old abandoned DID

I've definitely had this happen to me. I lived in a house with old copper that was poorly installed, but no actual service on it. Because I didn't need it, I never gave it any attention...until the second time cops showed up at the door thinking someone was being killed. To be clear, this phone

Re: [VoiceOps] False 911 calls and old abandoned DID

Interesting, here in AZ we just had rain for the first time in a long time. And yeah, Qwest has always left 911-only dialtone in place, which I think they are required to do. On Thu, Jan 21, 2021 at 1:08 PM Dan Mostert wrote: > We’ve run into similar circumstances before with ported in

That does raise the question of if they have other dial tone not managed by Carlos that may have initiated the calls though. Brandon Svec > On Jan 21, 2021, at 12:08 PM, Dan Mostert wrote: > >  > We’ve run into similar circumstances before with ported in numbers. The > losing carrier,

Re: [VoiceOps] False 911 calls and old abandoned DID

That sounds unbelievable. Do you really have evidence that a damaged cable somehow pulse dialed 911? I think the issue is something upstream like what data the PSAP is getting has been spoofed or is just inadvertently incorrect, for example. Brandon Svec > On Jan 21, 2021, at 12:08 PM, Dan

If the only thing tying them to the number is the CNAM, just go update the CNAM maliciously to Qwest? On Thu, Jan 21, 2021 at 3:01 PM Carlos Alvarez wrote: > We have a customer who has received two calls from the police because > "they" called 911, but they did not. The CLID shown is NOT one

Re: [VoiceOps] False 911 calls and old abandoned DID

We’ve run into similar circumstances before with ported in numbers. The losing carrier, either on purpose under the idea of “left in place dial-tone”, or laziness, leaves a copper PSTN line configured as the customer still. They also don’t maintain their aging copper, so particularly when the

[VoiceOps] False 911 calls and old abandoned DID

We have a customer who has received two calls from the police because "they" called 911, but they did not. The CLID shown is NOT one of theirs, but they think it might have been theirs many years ago. The CNAM on that number is their company name. Nobody answers the number, and it's with Qwest.
