OpenPhone is called Quo now, and it already texts missed callers.
Type openphone.com and you land on quo.com; its help center now says “Quo, formerly OpenPhone.” Two of its features bear on a missed call, and between them you may not need anything else.
The first is auto-replies. As of September 2026, Quo documents triggers for missed calls, new voicemails, and incoming texts, each with an after-hours version. Quo sends each at most once every three hours per contact, and not at all if you recently contacted that person. It comes with every plan: Starter $19, Business $33, Scale $47 per user per month, billed monthly (Quo pricing).
The second is Sona, Quo's AI agent. It can answer calls by voice, priced in credits (Sona pricing), and a newer mode, lead capture over SMS, texts back a missed call from a number with no history, answers from what you trained it on, and hands the thread to your team with a summary. It's in beta and free on every plan for now.
Three ways a Quo line can answer a missed call.
A fixed auto-reply reads the same to a new lead and to a regular whose spring treatment is due. Sona writes per conversation, but only for numbers it has never seen.
| Quo auto-reply | Sona over SMS (beta) | Managed agent | |
|---|---|---|---|
| What sets it off | A missed call, a new voicemail, or a text, with separate after-hours versions | A missed call or first text from a number with no history in the inbox | A missed call that Quo forwards to the new number and that rings out there too |
| What the text says | The one message you wrote, to everyone | Written per conversation from the Knowledge doc you train it on | Written per call from your hours and records, then checked by a second model against your prices, hours, and links |
| Callers you already know | Get the same message | Not triggered; your auto-reply handles them | Greeted by first name when your customer list is in HubSpot and they're on it |
| Replies from | Your Quo number, in your Quo inbox | Your Quo number, in your Quo inbox | A separate toll-free number, logged to HubSpot or a webhook tool |
| Cost, as of September 2026 | Included on every Quo plan | Free on every plan while in beta | $249/mo + $850 setup + usage |

Switching on the Quo auto-reply takes one settings page.
Registration is the slow part: Quo says most approvals take 24 to 48 hours, some sit for up to 20 days, and no text reaches a US number until it clears (carrier registration).
- 01
Finish carrier registration (A2P 10DLC) for the number first.
- 02
Open Quo on the web or desktop app; the mobile apps can't set auto-replies.
- 03
Click Settings, then Phone Numbers under Workspace settings, and pick the number.
- 04
Open the Automations tab and scroll to Auto-Replies.
- 05
Write a message for Missed calls, and for the after-hours version if you want one. After-hours replies follow the business hours set on the number.
- 06
Call the number from a phone Quo hasn't seen recently, let it ring out, and read what arrives.
A fixed reply that holds up for everyone

Saltmarsh Pest Control is made up. A text every caller gets should promise only what is true of every call: a call-back and a booking page. It asks no question, because nothing reads the answer until you do.
If Sona's SMS beta has reached your workspace, it sits under Sona, then Messaging (Beta): train it in the Train tab, then test and switch it on in Activate. Quo says Sona takes new conversations and your auto-reply covers the rest, so nobody gets two texts. That pair is a sound free setup.
Quo keeps ringing your team. A forward step catches what nobody answers.
There is no Quo plug-in. In Quo's call flow builder you drag a Forward call step in after Ring users and enter the toll-free number provided at setup. Per Quo's forwarding article, external forwards work to any US or Canadian number and keep the original caller's number as caller ID, the number the agent texts. Forwarding only unanswered calls is a Business or Scale feature on Quo's pricing page; Starter can only forward every call.
On arrival the new number rings your cell for 20 seconds, then plays a one-line apology promising a text. Landlines and withheld numbers are dropped before anything is spent, so those callers hear the promise and get nothing, as does anyone calling after 8 pm. Someone who hangs up while your cell is still ringing gets no text and leaves no entry in the agent's log; only your phone's recent-calls screen shows they tried. The first text names your business, flags itself as automated, and closes with STOP instructions. With no voicemail on this path, the answer follows the caller's reply.
The trade-offs: Quo won't record, transcribe, or voicemail a call it forwarded out. The thread lives on the new number, not in your shared Quo inbox, and logs to HubSpot or a webhook tool. In return, a person trains the agent on your site, sends rehearsal drafts, and reads a copy of every live text for the first weeks. The reply rules are described in Twilio's messaging policy; ask your counsel how they apply to you. The Twilio page covers the number underneath.
Free versus $249 a month is a real comparison here.
Quo's options cost nothing extra for now, so the managed agent has to earn its whole bill. Year one, using the high end of usage: $4,318.
At an example $240 first visit, the agent must win 18 jobs a year that the free Quo reply would have lost. Run the auto-reply for a month and count the callers you still lose. That count decides it. Full terms are on the pricing page.
Most Quo users should start with what they already pay for.
Stay native if your team lives in the shared Quo inbox and wants every reply there. Stay native if the calls you lose come at night: Quo has an after-hours auto-reply, and the managed agent stays quiet from 8 pm until 8 am. If the Sona beta is on and most missed callers are new, give it a month.
Pay for the managed agent when you want someone else to build and watch it, when a wrong price in a text would hurt, or when regulars call often and deserve more than a canned line. It's $249 a month plus $850 setup, plus AI and phone usage, typically $20–40 a month. The mechanism is on the main missed-call text back page. On RingCentral instead? See the RingCentral setup. Desk-phone callers are covered in the landline page.
