We called 48 Houston firms after hours. Only 6 picked up.

42 of 48 Houston firms (87.5%) did not have a person answer after hours. 22 went to voicemail, 13 to a phone menu or recorded message, and 4 rang with no answer. None of the 11 civil engineering firms or 10 CPA firms we called reached a person. Law firms did best, with 3 of 10.

On a phone, swipe the table sideways to see every column.

"Reached a person" includes one medical answering service. "Other" is one CPA firm that answered with an AI-style automated assistant and two calls where the line stayed silent until it timed out.

• Voicemail is the default. Nearly half the calls (22 of 48) ended at a voicemail greeting. One mailbox was full and couldn't take a message at all.
• Phone menus don't help a new caller. 13 firms answered with a menu or a recording that listed office hours or asked for an extension. A first-time caller doesn't know the extension.
• Almost nobody offered another way in. Only 1 of 48 greetings pointed the caller somewhere else (an email address for urgent requests). None offered a text, a booking link or a callback.
• AI answering is still rare. Only 1 of the 48 firms, a CPA firm, answered with an automated assistant.
• Engineering and accounting are the most exposed. 0 of 21 civil engineering and CPA firms reached a person, the two groups that most often get calls from developers and business owners outside office hours.

Many people call a professional firm after work, because that's when they have time. If nobody answers, a lot of them call the next firm on the list instead of leaving a message. An after-hours call that goes to voicemail isn't just a delay; it's often a lost client.

The fix doesn't have to be a night receptionist. An AI voice agent can answer every call in the firm's name, answer common questions, take the details and book a callback or appointment, then hand everything to a person in the morning.

• Who: 48 Houston-area professional firms with public office numbers on Google: 11 civil engineering firms, 10 CPA firms, 10 law firms, 6 insurance agencies, 6 medical clinics and 5 real estate brokerages. We used main office lines only and removed any number that looked like a personal cell phone.
• When: Thursday, November 5, 2026, between 7:34 and 7:58 PM Central. Most firms list a 5 PM close (a few close at 4 or 6 PM), so every call came one to three and a half hours after closing.
• How: one call per firm, placed by an automated assistant that said it was an automated study call from The Lyceum Group, apologized for the interruption and hung up. It didn't sell anything, leave a sales message or ask for anyone's details. Each call lasted under 45 seconds.
• Scoring: each call was logged as a person, an answering service, an AI assistant, a phone menu or recording, a voicemail, or no answer, from the call recording and transcript.
• Privacy: we publish totals by industry only and never name a firm. Nobody asked to be removed from future calls.
• Limits: this is one evening and 48 firms, not a national survey. Treat it as a snapshot, and expect daytime numbers to look very different.
