Trunks and numbers for the customers you serve

Reselling voice works when every customer is provisioned the same way, kept separate from the others and supported within clear boundaries. We work with partners to set up that structure before the first customer goes live.

Partner arrangements

How reseller arrangements work

Resellers usually buy SIP trunks and numbers under one partner agreement and provide them to their own customers under their own brand and contracts. Commercial terms, including pricing structure, minimum commitments and billing arrangements, are agreed with each partner individually. We do not publish a reseller price list.

Provisioning

A customer provisioning workflow

Following the same steps for every customer keeps records consistent and makes later changes straightforward.

  1. Customer verified

    You confirm the end customer’s identity and business details, and keep the records your agreement requires.

    Input: KYC records

  2. Sub-account or trunk created

    A separate trunk or sub-account is set up for the customer, with its own credentials or IP allow-list.

    Output: customer account

  3. Limits applied

    Channel limits, enabled destinations and alert thresholds are set for that customer’s expected use.

    Output: customer limits

  4. Numbers assigned

    New numbers are requested or existing numbers ported, with any regulatory documents supplied for the customer.

    Output: number inventory

  5. Configured and tested

    The customer’s PBX is configured with the trunk values, and calls are tested in both directions before handover.

    Output: test record

Per-customer separation

Keeping each customer separate

Shared credentials and pooled limits make billing, troubleshooting and fraud response harder. Separation is set up from the start.

  • Separate credentials

    Each customer authenticates on its own, so a compromise at one customer does not expose the others and can be isolated quickly.

  • Separate limits

    Channel caps and destination permissions are set per customer, sized to that customer rather than to your whole base.

  • Separate numbers

    Numbers are assigned to individual customers, which keeps routing, porting and regulatory records accurate.

  • Separate records

    Call records can be identified per customer, where available, so you can bill and answer queries without manual splitting.

KYC and fraud prevention

Knowing your customers and limiting misuse

A reseller is responsible for who uses the service it resells. Identity checks and usage controls work together.

Know your customer

Verify each end customer’s identity and business details before activation, and keep those records for as long as your agreement and local law require. Many regulators also require the end user’s name and address before a number is issued, so the same information is often needed for number requests.

Fraud prevention

  • Apply channel limits per customer and open international or premium-rate destinations only on request.
  • Prefer IP authentication; where registration is needed, issue long, unique credentials per customer.
  • Route usage alerts to your own operations team so unusual traffic is seen out of hours.
  • Do not accept customers whose intended use conflicts with the acceptable use policy.

Numbers

Number provisioning for your customers

Numbers are requested per customer, so each one is tied to the right account and the right documents.

New numbers are requested by country and type (local, national or toll-free) and checked for availability. Where the regulator requires documentation, such as proof of a local address, you supply it for the end customer. Existing numbers can often be ported with a letter of authorisation signed by the customer who holds them.

Keep an inventory that links every number to a customer and a routing destination. It is the record you will need for porting, regulatory queries and customer departures. See Understanding DIDs and virtual numbers for the details.

Support boundaries

Who supports the end customer

Compatibility information and configuration values are shared with your engineers so they can support customers directly.

FAQ

Questions from resellers

Will our customers deal with you directly?

Normally not. You own the customer relationship and provide first-line support; we support you. The exact arrangement, including any escalation paths, is set out in the partner agreement.

Do you publish reseller price lists?

No. Commercial terms are agreed with each partner, based on expected volumes, destinations, number requirements and the support model. You receive an itemised proposal.

Which customer PBXs are supported?

Standards-based IP PBXs usually connect, including Asterisk, FreePBX, 3CX, FreeSWITCH, Yeastar and Grandstream UCM. We share compatibility notes so your engineers can configure each customer consistently.

What happens if one of our customers is affected by fraud?

Because each customer has separate credentials and limits, the affected account can be suspended without interrupting your other customers. Channel caps and destination restrictions limit the exposure while the cause is found.
