Your team's usage
Adjust every assumption1 member100 members
How many people will use the calling and messaging workspace?1 number100 numbers
Numbers and members are separate. For example, 10 team members can share just 1 phone number. Number charges depend on the number of phone numbers, not the number of members.
Your current monthly bill = members × current plan price per member, plus any extra fees you add below.
Advanced: edit Twilio rates & extra charges
The team-member and phone-number sliders are independent. The default uses 10 members sharing 1 number. Estimates reflect a simplified U.S. outbound browser-to-phone scenario. Actual Twilio costs vary by route, country, inbound usage, SMS carrier fees, registration, features and taxes. Review the voice and messaging rates.

Rather than comparing unrelated plan features, here's the structural difference in how your phone stack is billed.
| What matters | Typical per-seat phone SaaS* | CallFlow BYOT |
|---|---|---|
| Platform subscription | Often increases with user count | $79/month flat platform fee |
| Adding another teammate | May increase monthly seat charges | No additional platform seat fee |
| Voice & messaging charges | Depends on provider and plan | Usage billed on your Twilio account |
| Carrier-level account | Depends on provider's service model | Your own Twilio account |
| Setup approach | Provider-managed bundled service | Connect Twilio to your workspace |

CLARITY BUILDS TRUSTOwn the relationship.
Own the relationship.
Understand the costs.
A phone platform should make your business communications easier to manage, not harder to understand. See the key questions before you connect.
- Your Twilio subscription remains yours. Review your usage, numbers and charges directly in Twilio.
- Understand what's separate. CallFlow subscription and Twilio usage are two distinct bills.
- Know before connecting. Ask about credential handling, account permissions and disconnect procedures.
Questions about Twilio credentials & access?
Connecting a carrier account is a serious decision. We recommend confirming the permissions requested during setup, how credentials are handled, and what happens when access is revoked.
Ask for a detailed overview of the security controls used in your workspace before connecting a sensitive account.

Need to move existing numbers? Ask about setup and number-porting assistance. U.S. ports typically take 5–15 days after complete paperwork, sometimes longer, and are controlled by the carriers — not a guaranteed 24-hour move.
COMMON QUESTIONSGood questions.
Good questions.
Clear answers.
What to know before connecting your Twilio account or starting the trial.
What does “Bring Your Own Twilio” mean?
You use your own Twilio account for supported voice and messaging services. CallFlow provides the team-facing dialer, inbox and CRM interface. Twilio bills your account directly for telecommunications usage, while CallFlow bills the platform subscription.
Do all my team members need separate phone numbers?
No. Depending on your configured call routing, multiple team members can work with the same Twilio phone number. The calculator lets you choose team members and phone numbers independently: members affect estimated usage, while phone-number rental is based on the number of numbers you choose.
Is the total monthly cost really only $79?
$79/month is the CallFlow platform subscription. Twilio charges for call legs, messages, phone numbers and any other enabled services separately; carrier, registration and tax charges can also apply. Use the editable savings calculator to model your likely total.
Can my team use existing phone numbers?
Eligible numbers already in your Twilio account can be configured through the supported onboarding flow. You may also be able to port numbers to Twilio, subject to eligibility and carrier rules. For U.S. numbers, Twilio describes a typical standard porting window of 5–15 days after submission of complete information, with delays possible. Read Twilio's porting guidance.
Is the demo above making real calls or sending texts?
No. It's a simulated, interactive preview of the interface. Live calls and messages are available only inside a configured CallFlow workspace connected to Twilio.
What about account access and credential security?
You should review the access requested by any Twilio-connected application, including credential storage, available permissions, revocation and support procedures. For exact details of CallFlow's deployment and practices, contact the team before connecting sensitive accounts.
Can I use Twilio outside the U.S.?
Twilio product availability, number eligibility, local regulations and pricing differ by country. The calculator currently uses editable U.S. examples only. Confirm coverage for your operating countries and intended voice or messaging use cases before subscribing.
How do I start the free trial?
Choose “Start free trial” to go to the account creation page. The landing-page preview works independently of a Twilio connection, but live calling and messaging require a properly configured account.
