SIP Gateway bulk sign-in signs in shared accounts in batches of up to 100 devices, with at most 3 concurrent batches per region. It works only within 72 hours of onboarding, or within 7 days of a device being signed out. Accounts must have CommonAreaPhone policy, a phone number and AllowSIPDevicesCalling, and must not have MFA.
