Hangup Error Handling

The SDK now properly reports error causes when calls are terminated due to exceptions. When an error occurs during call setup or negotiation, the verto.bye message will include specific error information instead of the generic NORMAL_CLEARING cause.

Error Payload Examples

{
  "method": "verto.bye",
  "params": {
    "sessid": "session-id",
    "dialogParams": {

    "cause": "NORMAL_CLEARING",
    "causeCode": 16
  }
}

    "causeCode": 50002

Error Cause Codes

• REMOTE_SDP_ERROR_CAUSE_CODE 50004: Failed to set the remote session description during WebRTC negotiation
• EXECUTE_ANSWER_ERROR_CAUSE_CODE 50001: Failed to send an answer message to the server
• EXECUTE_ATTACH_ERROR_CAUSE_CODE 50002: Failed to send an attach message to the server
• EXECUTE_INVITE_ERROR_CAUSE_CODE 50003: Failed to send an invite message to the server

All error causes use the special error code 666 to distinguish them from standard telephony cause codes.
