At a recent conference, I learned about, which is a web-based service that facilitates telephonic court appearances for attorneys involved in matters in a wide variety of courts throughout the U.S. and Canada (click here to download a PDF of the entire list).  Fees range from $40 to $78 and the site notes that:

A Judge’s listing does not assure that Telephonic Appearances are allowed on all matters and deadlines for scheduling vary. Additional fees and restrictions may apply when scheduling less than three full ‘Court’ days in advance. Next-day appearances cannot currently be scheduled online.
