The only true way to mitigate is to have the ability to switch the traffic to an alternate carrier using the toll-free mgmt system (sms800). You¹d also have to keep your routing up to date on both carriers (which is usually a PIA) unless you are using the carrier as simple transport, and your company is doing all the routing/heavy lifting. If you¹re not already a RespOrg, switching the carrier on your number(s) is not an option for you. There are companies that offer this service (managing toll-free numbers independently), Custom Toll-Free (shameless promotion as they are a subsidiary of my company), and ATL Communications are two such companies. -Chris Message: 1 Date: Thu, 3 Sep 2015 15:14:06 -0700 From: Jim Witherell <jawitherell@yahoo.com> To: "Outages@outages.org" <Outages@outages.org> Cc: outages <outages@outages.org> Subject: Re: [outages] Anybody else having trouble with Centurylink toll-free #s?

Anyone have some research references on toll free outage mitigation or 'carrier redundancy"? My experience is the carrier is the single point of failure and you are absolutely 100% reliant on them. Ways to mitigate that? Whenever asked (and I just was), I say out hands are tied. I think that's true. Agree?? Sent from Yahoo Mail on Android
