Sean since I dont know your business Do you have any staff answering the calls? My staff takes the basic information that is on our intake sheet, tries to book appt to have client signed up for the work, usually Landlord Tenant or real estate related comes in off of my seo people’s efforts. If she cant reach an accord quickly I reach out later in the day, after returning from court. I tell the caller I am returning calls of the day and can spend just a few minutes confirming the details so I can call everyone back then we book appt. That five minutes helps me grade the potential client and depending on the feedback I either quote a fee for consult applied 100% to the work or a free consult for 15 minutes. Mostly the potential client is thrilled their call was returned and that usually sells the firm as one who gives a shit about their clients, which we do. if the person was referred by a client I waive the consult fee and send a thank you note to the person who referred me
