Calls a law office in Riverside, CA has to catch

A few of the calls that come in to law offices in Riverside, CA:
- Opposing counsel calls to discuss scheduling.
- Someone calls after a car accident to ask whether the firm handles injury cases.
- The firm calls a prospective client back after an online inquiry.
