VAPI seems like looting everyone due to its monopoly. Apart from the calling rate, the platform usage charges are almost $0.10 per min (including elevenlab voice), which is too much, An AI call may last for 3 mins on an average (outbound for promotional) and its like ripping us on the name of usage. We need to find or create an opensource like VAPI. Dont need all that features but atleast something that works. I know there exists LIVEKIT, but its not very friendly. Has anyone found out a solution that is much cheaper than VAPI?
