I have a requirement that I'm not sure is feasible with the Web SDK. Essentially, I have a custom calling service that can be used with VAPI. I want to use VAPI solely for voice-to-voice generation communication, meaning I'll provide voice to VAPI and receive voice from VAPI, and nothing else. Is this feasible? My flow might look like this: Voice from the custom calling service → VAPI → Generated response from VAPI → To the custom calling service. Also, I am new to voice bots. Please let me know if you have any other ideas regarding my requirement.
