You want students to report bullying, but not everyone feels comfortable talking to someone in person. Being able to call without having to say who you are might help students to speak up.
Hotlines are a great tool for someone feeling vulnerable to get help quickly. Most schools have anonymous reporting lines that could be helpful in the focus of your group. If your school does not have an anonymous reporting line, you can find out how to do it for free using Google Voice.
Here are some bullying and student support hotlines.
