<div dir="ltr">That's never a good thing. We were isolated for ~ 24 hours a couple of years ago and that's something I never want to repeat. <div><br></div><div>Funny story -- AT&T even called us and said "do you guys know that both your A-Kinks are down"? We replied with the AT&T ticket numbers on the circuits that were down and the SS7 folks said "yeah, we're not allowed to talk to those guys, hopefully they fix it soon". I don't think that escallate button on the ticket does what you think it does....</div><div><br></div><div>It was also a complete pain to try to get them to change routing for us. We had a neighboring company offer to give us a temporary link to their switch -- If memory serves that's a F-Link, but AT&T could never get the routing right.</div><div><br></div><div>Unfortunately, changing SS7 providers wasn't an option. One of the other SS7 providers (to remain nameless) could never actually get their circuits sent to the correct place.</div><div><br></div><div>This is making me think we should look at getting 2 more A-Links, so we have 4 again......</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jan 19, 2022 at 5:20 PM Mike Hammett <<a href="mailto:voiceops@ics-il.net">voiceops@ics-il.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:arial,helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)"><div>The links have since come back.
