Iowa Admin. Code r. 187-11.8
The presiding officer may resolve preliminary procedural motions by telephone conference or other electronic means in which all parties have an opportunity to participate. Other proceedings may be held by telephone or other electronic means with the consent of all parties. The presiding officer will determine the location of the parties and witnesses for hearings held by telephone or other electronic means. The convenience of the witnesses or parties, as well as the nature of the case, will be considered when location is chosen. Disciplinary hearings will generally not be held by telephone or electronic means in the absence of consent by all parties, but the presiding officer may permit any witness to testify by telephone or other electronic means. Parties shall disclose at or prior to the prehearing conference whether any witness will be testifying by telephone or other electronic means. Objections, if any, shall be filed with the division and served on all parties at least three business days in advance of hearing.
