We have a small congregation and have used Call-em-all for prayer concerns as well as general announcements. We are most appreciative when we do prayer concern calls that everyone gets the same information (without editing), and they all get it at the same time. Many have learned to let answering machines get the messages when they come from our number so that they can listen again later. We have many sub-groups in the call-em-all system which makes it easy to remind committees of meetings or to announce a church closing when the parking lot is covered with snow and ice.
