    Toll-free call forwarding that your team can actually manage

    Pick a toll-free number from live inventory, attach it to a campaign and forward its calls to the phones, SIP trunks or browser agents that should answer, each with its own opening hours, capacity and failover. The same portal shows the calls as they ring, keeps the recordings and itemises every charge.

    What you get

    A toll-free number plus everything needed to run it

    The number is the easy part. These are the controls that decide whether the calls actually reach someone who can help.

    Live number search

    Filter the inventory by toll-free prefix and by digits the number must contain. Numbers attach to your account the moment the order completes.

    Three kinds of destination

    A campaign can forward to an ordinary phone, to your PBX or dialer over SIP, or to agents answering in their browser, in any mix.

    Hours and failover

    Each destination has its own daily or dated schedule and a ring time. A closed or unanswered destination is skipped and the next one rings.

    Call Protection

    STIR/SHAKEN checks, per-caller rate limits, a block list with reasons, optional VoIP and international blocking, and an IVR challenge.

    Live calls and call logs

    Mission Control shows calls ringing and talking right now; call logs keep the caller, the number dialled, the destination, duration and outcome.

    Wallet billing, no contract

    Fund a wallet and watch it draw down call by call in the transaction history. There is no subscription, and numbers are released from the portal.

    Inside the portal

    Numbers, campaigns and forwarding rules in one place

    Real screens from a CallFlow account (demo data). A campaign is the unit everything hangs off: it owns the numbers and the list of destinations.

    CallFlow campaigns page listing four campaigns with their toll-free numbers, routing mode and target counts
    Campaigns: each one lists its toll-free or local numbers, its routing mode and how many destinations it forwards to. Pause a campaign and its numbers stop forwarding.

    How it works

    From dialled number to answered call

    A toll-free call passes through Call Protection first, then the campaign decides which destination should ring, in what order, and for how long.

    1. 1

      Pick a number

      Search the inventory by prefix and digits. The number is yours as soon as the order completes and appears on the Numbers page.

    2. 2

      Create a campaign

      Name it, choose sequential or simultaneous ringing, set the ring time and attach the number. One campaign can carry several numbers.

    3. 3

      Add destinations

      Add phones, SIP destinations or agents as targets with a weight, a priority tier, caps and opening hours in your time zone.

    4. 4

      Switch on protection

      Turn on Spam Shield rules and, if the number is public, the press-a-digit IVR. Then watch the first calls arrive in Mission Control.

    Destinations

    Forward a toll-free number to a phone, a PBX or a browser

    Every destination type takes part in the same weights, priorities, caps and schedules, so you can start with a mobile phone and add a PBX later without rebuilding the campaign.

    Any phone number

    A mobile, an office line, an answering service. The caller's number is shown as the caller ID, so the person answering sees who is calling, not your toll-free number.

    • No equipment or app to install
    • Different phones for different hours
    • No-answer failover to the next phone in line

    Your PBX or dialer over SIP

    Point a target at a SIP destination on your own PBX, contact-centre platform or dialer. CallFlow sends the call to your host and port, and the dialled toll-free number travels with it so your system can route internally.

    • Plain SIP to an IPv4 host and port
    • The dialled number is passed as the SIP user part
    • Same caps, weights and hours as a phone target

    Agents in a browser

    Give team members an agent extension and they answer calls in the browser with a headset. Put several agents in an extension group to ring them all at once and connect the first to pick up.

    • No softphone download for the agent
    • Extension groups for simultaneous ringing
    • Agents see only their own calls and recordings

    Call Protection

    A public toll-free number attracts robocalls. Plan for it.

    Toll-free numbers are harvested and dialled by machines at scale. Call Protection is switched on per account and runs before any destination rings.

    • STIR/SHAKEN attestation: choose how strictly unsigned or weakly attested calls are treated.
    • Rate limits: cap how often one caller can reach you per minute and per hour.
    • Block lists: block specific numbers with a reason, and optionally all VoIP or all international callers.
    • Press-a-digit screen: a spoken prompt and a required key press, with a random digit per call if you want it. Details on the IVR call forwarding page.

    Blocked and rate-limited calls never ring a destination, so an after-hours flood of auto-dialer calls does not wake up the on-call phone.

    Who it is for

    Where toll-free forwarding earns its keep

    Multi-location businesses

    One advertised toll-free number, forwarded to each branch during its own opening hours and to a central desk or answering service outside them.

    Agencies and lead generators

    A separate toll-free number per client or campaign, each forwarding to that client's phone, with call logs and recordings the client can see in a buyer login.

    Remote and part-time teams

    Agents answer in the browser from wherever they are; simultaneous ring groups make sure the first free person picks up, and caps stop anyone from being flooded.

    Businesses moving off a desk phone system

    Keep the toll-free number public, forward it to the existing PBX over SIP today, and move individual departments to phones or browser agents when it suits you.

    Toll-free or local?

    Both forward the same way; the difference is what the caller sees

    CallFlow sells both. Many accounts run a toll-free number for the national line and local numbers for individual markets, all forwarding to the same team.

    FAQ

    Toll-free call forwarding questions

    What businesses ask before they move a toll-free number onto CallFlow.

    How quickly is a toll-free number live?

    Numbers are picked from live inventory inside the portal and are attached to your account the moment the order completes. You can put a number on a campaign and forward it to a phone straight away. New toll-free numbers can take a few hours to become dialable from every carrier in the country, which is normal for the toll-free network and nothing you need to configure.

    Which toll-free prefixes can I choose from?

    All seven North American toll-free prefixes: 800, 833, 844, 855, 866, 877 and 888. The number search lets you filter by prefix and by digits the number should contain, so you can find a memorable pattern without paying for a vanity-number service.

    Where can calls be forwarded to?

    To any phone number, to your own PBX or dialer over SIP, or to agents answering in their browser. A campaign can mix all three, and you can set weights, priorities, concurrent-call caps, daily caps and opening hours per destination.

    Can one toll-free number ring more than one phone?

    Yes. Add several targets to the campaign. Sequential mode rings them in priority order and moves to the next one when a target does not answer within the ring time; simultaneous mode rings a group of agents at once and connects the first to pick up.

    What happens to calls outside business hours?

    Each target has its own opening hours and optional start and end dates. Calls arriving when a target is closed skip it and go to the next eligible one, so an after-hours answering service or an overflow desk can sit behind the daytime team without any manual switching.

    How do you keep robocalls off a toll-free number?

    Call Protection runs per account: STIR/SHAKEN attestation checks, per-caller rate limits, a block list with reasons, optional blocking of VoIP or international callers, and a press-a-digit IVR challenge that can randomise the digit on every call so auto-dialers cannot learn it.

    Are forwarded calls recorded?

    Recording can be switched on per account. Recordings are available in the portal and to buyers you allow, and they are deleted automatically after ten days from both the server and cloud storage.

    Do I need a contract or a subscription?

    No. You open a free account, fund a wallet and usage is drawn from it as it happens, with every charge itemised in your call logs and transaction history. Numbers can be released from the portal when you no longer need them.
