Hey all,
Seeing some weirdness on trunk US-East-01 - intermittent 401 Unauthorized responses during registration attempts. It’s not a full outage, calls eventually get through, but the dialer’s choking a bit - about 3% drop rate when it hits.
The SIP options are configured as expected, credentials haven’t changed, and the carrier swears it’s not on their end. We’re on Genesys Cloud v8.5.30.13. It’s almost like the initial registration’s timing out before the auth can complete. A quick workaround’s been to bump the registration interval on the trunk to 300 seconds - seems to hold for now. Anyone else running into this?
Right, 401s on BYOC - classic. Honestly, intermittent auth failures are usually a timing issue, tbh. The registration attempts are probably colliding with some internal GC process. We’ve seen this a lot with the v8.5.x releases - they’re… rough.
Check your registrationInterval and expiryInterval settings on the trunk configuration. I’m betting your registrationInterval is set too aggressively - like, under 60 seconds. Try bumping it to 120, maybe even 180. The expiryInterval should be at least 3x the registrationInterval, obviously.
Also, look at the retryCount and retryInterval values. If those are set too low, it’ll just keep hammering the registration endpoint with failing requests. A retryCount of 3 and a retryInterval of 30 is usually a good starting point, imo.
Double-check the SIP profile too - the authenticationCredentials need to match exactly what the carrier’s sending. iirc, case sensitivity can be a pain.
