POST /api/v2/conversations/calls 400 malformed address

Is it possible to initiate a call with a plain SIP URI?

  • POST /api/v2/conversations/calls returns 400 Bad Request.
  • The documentation states: “The from and to addresses must be in the format of a URI.”
  • My payload is {"from": {"address": "sip:[email protected]", "addressType": "sip"}, "to": {"address": "sip:[email protected]", "addressType": "sip"}}.
  • The error message says “Malformed participant address” but the format matches the spec exactly.
