I have been trying to set up bridge-appr and it hasn't been working. I set each ext with a brdg-appr button and set a button to call-appr. I want ext 7209 to ring at 4 or 5 other locations. What do I need to set on the primary 7209 to have it bridge to the other phones? Now I have Bridge call alerting set to Y and nothing happens. What am I missing. Thanks for your help.
