Congested peering between ATT and Level 3

We use a cloud based phone system and after the recent power events here in Northern California my users are reporting issues with the phone system. After some investigation I narrowed the culprit down to the peering point inside of the ATT network before entering the level 3 network. We have a failover terrestrial microwave WAN circuit and our failover ISP has no congested peers along the way to the level 3 network. I know that manually cutting over to the failover line would resolve the issue. Should I try working with ATT to get the peering issue resolved (or just wait for that to happen on its own)? Or should I just force our router to use our failover line? Or both? Thanks.
