Hey everyone, i am trying to implement a custom telephony (vobiz) with Vapi. I am able to get the outbound working but inbound doesnt seem to work. The request is getting sent to sip.Vapi.ai with transport udp. But Vapi doesnt accept the response. I have added the phone number and assigned it to the agent as well yet, the call is not getting connected. Could someone please help me out here?
