+# Noon Chimes
+
+This is a simple setup to make your phone system page a page group and play a chime at noon in any number of timezones.
+
+## Installation
+1. Choose a chime sound and upload it to FreePBX through Admin > System Recordings.
+2. Set up a custom context in Admin > Config Edit. Paste the contents of `custom-context.conf` into the file, save, and apply the config.
+3. Set up a Custom Dest in Admin > Custom Destinations. Set the target to `chimes,s,1` and give it any description.
+4. Set up the script `chimes.sh` in `/root/chimes.sh` and make it executable with `chmod +x /root/chimes.sh`.
+5. Set up crontab with the following line: `0 * * * * /root/chimes.sh`.
+
+## Configuration
+There really isn't any, other than modifying the shell script to set what timezones you want to make chime at noon.
+If you want to trigger the chime at a specific time, use cron to run `/var/lib/asterisk/bin/callback "page-group-number-here" chimes.s.1 0 0 "Ik5vb24gQ2hpbWUiIDw+"` at the desired time. I think you should be able to look up how to set up a cron job for that.
+
+If you want to change the Caller ID it uses, base64 encode the callerid string you want to use and replace that at the end of the callback command.
+A valid caller id looks like `"NAME" <NUMBER>`, or just `"NAME"` or `<NUMBER>`. The base64 encoded string for `"Noon Chime" <1234>` is `Ik5vb24gQ2hpbWUgPDEyMzQ+`.
