OAC Rule 22. Testimony by Telephone, Videoconference or Other Electronic Means.    

A.  An endorsed witness may testify by telephone, videoconference or other electronic means if the party calling the witness has so advised in the Case Information Sheet or has given all parties written notice at least five working days prior to the hearing.  The party calling a witness by telephone, videoconference or other electronic means must do so at its expense, and must make advance arrangements for a speakerphone in the hearing room, or other arrangements as necessary for testimony by videoconference or other electronic means.  Advance arrangements for a speakerphone need not be made if the hearing is set to occur in Denver, Colorado Springs, Pueblo, or Grand Junction.

B.  An opposing party, at its expense, may compel the attendance of a witness who would otherwise testify by telephone, videoconference or other electronic means by serving a subpoena upon the witness.
