Couple things to keep in mind – Consider handling 112 and 999 if your service might be used internationally. Also – not sure where the current regulation is on this, but the requirements around 911 suggest handling all sorts of additional dialing patterns, e.g., 1010xxx911, et al. Much of this is legacy, but be aware. /Ed From: VoiceOps <[email protected]> on behalf of Carlos Alvarez <[email protected]> Date: Tuesday, March 24, 2020 at 11:20 AM To: "[email protected]" <[email protected]> Subject: Re: [VoiceOps] Three Digit Numbers We're in the US, and yes 811 is the underground utility line, but I don't think any of our carriers will pass it. I don't recall the details on who does what, but carriers like Intelliquent, Bandwidth, and thinQ all do 911 testing on 711/811. Yeah, I just tried 811 to Intelliquent and it read back my phone number. On Tue, Mar 24, 2020 at 8:14 AM Mike Hammett <[email protected]<mailto:[email protected]>> wrote: What country is this? I believe 811 is supposed to be a USA-wide number to call for locating utilities for digging projects. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ________________________________ From: "Carlos Alvarez" <[email protected]<mailto:[email protected]>> To: [email protected]<mailto:[email protected]> Sent: Tuesday, March 24, 2020 10:10:37 AM Subject: Re: [VoiceOps] Three Digit Numbers We don't handle any others in a traditional way. Well, 611 is actually in place, to our support line, but it has never once been used. 811 and 711 are used for 911 testing without a real 911 call, as carriers mostly use those for automated systems that return your 911 info.

Obviously there's 911 and that has a whole routing ecosystem. What about 811? 311? X11? What other special numbers are people handling? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com _______________________________________________ VoiceOps mailing list [email protected]<mailto:[email protected]> https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list [email protected]<mailto:[email protected]> https://puck.nether.net/mailman/listinfo/voiceops
