OpenPhone (now Quo) alternatives for a shared business line
5 alternatives and the baselineVendor claims read 2026-10-22
For a small team that calls and texts customers from one shared business number and is weighing a move. OpenPhone is now called Quo: its own changelog announced the new name on 2025-09-23, and openphone.com redirects to quo.com. Quo is the first column, read from its own resource centre; five phone systems follow, each read from its own help pages on 2026-10-22. More side-by-sides sit in the comparisons index.
Verdict by use case
Best overall
A STOP blocks the contact for every number on the same registered campaign, so a second line on the account cannot text them by mistake, and a greeting is mandatory on recorded shared-line calls. Its SMS export carries each message's delivery status and A2P registration status.
Best for catching every FCC reply word
Its opt-out list recognises all seven reply words the FCC rule names, and admins can view and export the whole account's opt-out list. Plan around one gap: the block is per pair of numbers, so your other lines need that list honoured too.
Best for teams that call and text out
One Compliance Center page carries the business profile, 10DLC campaigns, caller ID name and toll-free registration. A STOP to a bulk text blocks the contact across the whole account by default, and with its recording-compliance switch on, outbound recording stays off by default on calls into all-party states.
Six phone systems, ten rows
A shared line carries texts and calls, so the rows mix both: four texting rows from the FCC's rule (47 CFR § 64.1200) and CTIA's guidelines, one row for who sent what on a shared inbox, two recording rows, caller ID, message export and porting. Quo is the first column; "Our pick" marks the best-overall verdict.

- 10DLC brand and campaign registration in-product
- US carriers route business texts on local numbers through registered brands and campaigns.
- Honours STOP and plain-language revocation automatically
- The FCC rule names seven reply words and also counts any reply a reasonable person reads as a revocation.47 CFR § 64.1200(a)(10)

- Shows which teammate sent each text on a shared number
- When several people text from one line, the thread has to show who wrote what, so a consent question or a missed opt-out can be traced to a person.
- Records inbound and outbound calls automatically
- A recording policy only works if it covers every line it is meant to, without agents remembering.Reporters Committee, Reporter's Recording Guide: Introduction

- Customers reply to the numbers they already know; keeping them keeps STOP and HELP replies reaching you.
Reading the rows for a shared line
Registration is the one row every tool clears: all six run 10DLC registration from inside the product, which is what lets a local number text US customers at all (the 10DLC guide explains the brand and campaign steps). The texting records are where they all fall short. None documents a stored time and source for each opt-in, and none documents a hold that keeps texts inside the customer's own 8 a.m. to 9 p.m. window. On a shared line, keep the opt-in proof in your own consent log (the Records guides and tools cover what it holds) and check sends against the quiet hours checker.
The calling rows are stronger. Every tool records automatically, and five of the six document an announcement the caller hears; Dialpad can play it only to callers from two-party-consent area codes. Grasshopper is the one "No" on export: texts cannot be downloaded, and its page says SMS history is deleted when the number is ported away. Read the call recording comparison for the recording rows in more depth; the dialer comparisons and the calling-hours and Do Not Call guides sit in the Calling pillar.
Where one STOP lands on a shared line
A team with two or three numbers on one account has a question a single-number texter never meets: when a customer opts out on one line, does the block reach the others? The six tools give six different answers.
- 01 A customer replies STOP to a reminder from your front-desk number.
- 02 Eight days later a teammate texts the same customer an invoice link from the billing number.
- 03 Does the second text go out?
| Tool | What the STOP blocks | The billing number's text | Opt-out list an admin can open |
|---|---|---|---|
| Quo | Every Quo number on the account, not only the one the customer replied to. | Fails, with a "Failed" status in the thread. | None. Quo's own FAQ says it has no master opt-out list; failed sends in a thread are the sign. |
| Dialpad | Every number on the same registered campaign: no one in the company can text the contact. | Blocked; the message box closes with a grey notice. | Readable through Dialpad's SMS Opt Out API. |
| Aircall | Only the number that was texted. Aircall's page says to block the contact on your other numbers by hand. | Goes out unless someone blocked it. | Not described. |
| JustCall | The whole account, for a STOP to a bulk text. A setting narrows it to the one sending number. | Blocked, unless the per-number setting is on. | Restricted Contacts, with a download of every Do Not Message entry. |
| RingCentral | That business number and that customer: opt-outs are kept per pair of numbers. | Goes out unless the opt-out is added for that number too (the API can push it). | Admins view and export the opt-out list for the whole account. |
| Grasshopper | Not described in the help pages read. | Not described. | Not described; texts cannot be exported at all. |
Each vendor's own help page, read 2026-10-22; sources at the foot of the page.
The FCC rule speaks of a customer who no longer wants calls or texts "from the caller or sender", and gives the business at most 10 business days to honour it (47 CFR § 64.1200(a)(10)). That is your business, not one of its lines. Where a tool blocks per number, someone has to carry each opt-out to the other numbers inside that window, and keep a record that they did.
The words that trigger the block matter as much as its reach. Quo and Dialpad document short keyword lists and Aircall gives examples; only RingCentral's list carries all seven reply words the rule names. A reply such as "please stop texting me" still counts if a reasonable person would read it as a revocation, so whoever watches the shared inbox needs to know what to look for (the opt-out keywords guide lists them, and the texting rules guide tracks the FCC's 2026 order on revocation methods, adopted but not yet in effect).
Vendor by vendor
Each card repeats the table's rows with the detail from the vendor's own page. Caller ID names sit in more depth in the branded caller ID comparison.
Quo (formerly OpenPhone)

How we read the claims
Questions switchers ask
Is OpenPhone the same company as Quo?
Yes. OpenPhone announced its new name, Quo, in its own changelog on 2025-09-23, and said numbers, conversations and team setup stay the same. openphone.com now redirects to quo.com, and the help centre calls the product "Quo, formerly OpenPhone". Anything you read about OpenPhone's texting rules applies to Quo.
Does every number on a shared line need its own 10DLC registration?
It depends on the provider. In Quo, an approved business registration clears every number in the workspace to text US numbers, while a sole-proprietor registration clears only one. Grasshopper asks you to select each number in its registration assistant. Either way, an unregistered local number cannot text US numbers, so register before or at the same time as you port a number in.
Quo says 14 states need all-party consent to record. Is that right?
Lists differ. The Reporters Committee's compendium counts about 11 states that primarily require all-party consent, plus Connecticut and Nevada for phone calls; JustCall's built-in list also includes Puerto Rico and Vermont. Federal law needs one party's consent (18 U.S.C. § 2511(2)(d)), and a call across state lines can fall under the stricter law. An announcement on every recorded call, inbound and outbound, avoids having to pick a list.
What stays behind when we leave Quo?
Quo's owner-only export gives contacts, call logs and message logs as CSV files, emailed within 24 hours with a link that expires after 72 hours. Recordings, transcripts, voicemails, media and internal threads are not in it, and workspace data is deleted 30 days after cancellation. Quo has no master opt-out list either, so search the message log for opt-out replies and carry those numbers into the new tool as opted out before anyone texts from it.
Does a STOP text also stop phone calls?
Not in the software. Dialpad's page says a contact who replied STOP can still receive calls from that number. A spoken "don't call me" is a separate do-not-call request: for telemarketing calls the FCC rule says it must be honoured within 10 business days and kept for 5 years. On a shared line, put both kinds on one list the whole team checks.
