Anyone have issues with using VAPI for outbound calling? I am based in Canada, I purchased a Telnyx US number, successfully imported into VAPI, then made a call using the /call end point. I am getting the following 2 problems: a. either the call never happens with the error 'Assistant could not get audio' b. or when the call does happen, the agent can hear the user by the end user cannot hear the agent. I noticed this in the call recordings in the Call Logs. And yes, calling US numbers using US Telnyx number. Has anyone encountered this before? do u know a fix?
