CompleteLine vs Ruby
CompleteLine vs Ruby: live people per minute, or an AI front desk per month
Ruby is a well-regarded live answering service: real receptionists, 24/7, billed by the minute. CompleteLine is an AI front desk that answers, texts back and books the job, at a flat monthly price. Which one fits depends on how many calls you get and how much a human voice matters to your callers.
Two different products, honestly compared
Short answer: if your callers expect a human every time and you get a modest number of calls, Ruby is the safer choice. If you get a lot of calls, want every missed call followed up by text, and want jobs booked without a person in the loop, CompleteLine costs far less per call.
Ruby sells minutes of live receptionist time. Its people answer in your business name, take messages, transfer calls and follow your instructions. CompleteLine Pro answers with an AI receptionist that says it is an AI, answers questions from your business profile, books the appointment, and texts back any call that is not answered.
Pricing
Ruby’s published plans (as of October 2026) are $250/mo for 50 minutes, $395 for 100, $720 for 200 and $1,725 for 500, with 24/7 live answering. CompleteLine Pro is $499/mo with 500 AI receptionist minutes, 2,000 texts, missed call text back and review requests included, plus a one-time $1,000 setup. Core, without the phone receptionist, is $249/mo plus $500 setup.

| Missed call follow-up | Every unanswered call gets a text in about 5 seconds and an AI conversation | Calls are answered live, so fewer are missed; text follow-up is not the core product |

When Ruby is the better choice
- Your callers expect to talk to a person, every time — legal intake, sensitive situations, or calls that need judgment.
- You get a modest number of calls a month, so per-minute pricing stays affordable.
- You need warm transfers and message-taking more than automated booking.
When CompleteLine is the better choice
- You get enough calls that per-minute live answering gets expensive: 500 minutes is $499/mo with Pro versus $1,725 on Ruby’s published plan.
- You want every missed call followed up by text in seconds, not just answered when someone is available.
- You want the job booked, a review requested afterward, and one flat monthly price.
- You are fine with callers knowing they are talking to an AI. CompleteLine always says so.
Common questions
Is an AI receptionist as good as a live answering service?
For routine calls (hours, pricing questions, booking a visit) an AI receptionist handles the job well and never puts anyone on hold. For calls that need human judgment or empathy, a live service like Ruby is better. Many businesses only need the routine part covered.
Will my callers know they are talking to an AI?
Yes. CompleteLine’s receptionist says it is an AI at the start of every call, and that the call is recorded. We do not offer a way to turn that off.
What happens when CompleteLine Pro uses up its 500 minutes?
Calls fall back to instant text-back for the rest of the billing period, so no caller goes unanswered. Live answering services typically bill overage minutes instead.
Try the difference on your own phone
Once your texting is approved, miss a call and watch CompleteLine text back in about 5 seconds and hold the conversation. From $249/mo plus a one-time $500 setup, month to month, 30-day money-back guarantee.
