FAQ
Does Voice Service support real-time full-duplex calls with an Agent, or SIP integration?
Voice Service does not currently support having an Agent place a call and conduct real-time full-duplex communication with the callee. SIP integration is not supported either, so real-time communication cannot be implemented through SIP. Voice Service only supports dialing a specified callee number using a fixed voice verification code or notification template.
