Updates from Vapi 2

1. updateSep 9, 2026, 12:00 AM UTC

   We're performing routine maintenance on our telephony infrastructure in the EU region. *Users of the US regional deployment will not be affected (dashboard.vapi.ai, api.vapi.ai, sip.vapi.ai)* When: Wednesday, September 9 2-2:15am CET (Tuesday, September 8 5-5:15pm PT) What to expect: There will be downtime at 2am in which calls made using Vapi Numbers, directly via our SIP infrastructure, or via SIP trunk will not connect and fail immediately. After, there will be a period where we monitor and validate the maintenance but calls will start connecting again. Action needed: If there are concerns around minutes of downtime, customers can configure an alternate transport (i.e. Twilio) for calls. We'll update this page as the maintenance progresses when SIP calls should be back online and when the update is completed altogether.
