Hey thing is we got an Ai voice agent that can book meeting in call, it works perfect with our us numbers on twiliow but we got swedish numbers too so we hade to switch to telnyx but we dont know how to connect them so they can book in ghl calender right now it only makes the call and adds the contact to a pipeline but it cant book the meeting becuse of some missing API or webhook conection with the number. can someone help with this ?
