Prayer Groups by Telephone Conference Call. Another idea for praying together when it is not physically possible to be together in the same room is to have a telephone conference call. There are several providers for free conference-call services. It is even possible to add video so you can see as well as hear one another. This works best for groups that have already prayed together in person, so it is something they can do after camp and between regular meetings. Many CFO Council Rings have adopted this practice and report good fruit.
