SIP creds on the Ohio BYOC trunk group got rotated via the admin console. Architect v2024.3.1 is running the show. Console shows SIP 401 Unauthorized on the REGISTER attempts right after the push. Bandwidth carrier side is green, logs show the auth header matching the new secret. Outbound routing still points to the old trunk object ID somehow. Priority swap to the secondary Twilio trunk works, so it’s definitely the Ohio pool choking on the auth handshake. Curl request to the trunk config endpoint returns the updated credentials, but the SIP stack isn’t picking it up.
