Should I reach out to each company's NOC if they're still sending traffic over the tandem? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com From: "Mike Hammett" <voiceops@ics-il.net> To: "Mike Hammett" <voiceops@ics-il.net> Cc: "voiceops" <voiceops@voiceops.org> Sent: Friday, November 14, 2025 7:50 AM Subject: Re: [VoiceOps] Migration from TDM and Tandems to PSTN-Connect Everything so far seems to be working, which it should, and that makes me glad. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Mike Hammett via VoiceOps" To: "voiceops" Sent: Thursday, November 13, 2025 12:13:27 PM Subject: [VoiceOps] Migration from TDM and Tandems to PSTN-Connect Tomorrow is the LERG effective date for our migration from TDM to using Sinch's PSTN-Connect. We have verified calls flow via testing with our consultant (Award) and Sinch. Given that this is pretty monumental and there doesn't appear to be as easy a "backing out" as there is with the Internet, what are the things I should triple-check? What are the things I should be watching? What are the tests I should be doing to ensure everything is 100%? Also with a LERG effective date, is that at midnight local time, or some other time when calls start flowing differently? When do I switch my Metaswitch to passing calls via Sinch instead of the tandem? I have asked Sinch and my consultants similar questions, just as a kind of sanity check. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com _______________________________________________ VoiceOps mailing list -- VoiceOps@voiceops.org https://lists.voiceops.org/postorius/lists/voiceops.voiceops.org/ To unsubscribe send an email to voiceops-leave@voiceops.org
