31106: Invalid data

31106 means the data passed to the Voice SDK was not valid. On Android, Voice.handleMessage(context, data) returns false when the data is not a Twilio Voice push message, and CallInvite.isValid(...) validates whether a payload is a valid notification sent by Twilio.

• You passed a payload to Voice.handleMessage(context, data) that is not a Twilio Voice push message.
• The payload does not pass CallInvite.isValid(...) for a Twilio Voice notification.

• Call CallInvite.isValid(...) before you process the payload, and only continue when it returns true.
• Use Voice.handleMessage(context, data) only for Twilio Voice push messages, and treat a false return value as non-Voice data.
