Why DIDHub for VoIPstudio

  • 130+ country DID coverage. VoIPstudio’s bundled inventory is strong in core markets; for the long tail (parts of Africa, smaller Asian markets, regulated EU jurisdictions), DIDHub fills the gap with per-country regulatory clarity shown before you buy.
  • STIR/SHAKEN A-attestation. US and Canadian outbound from VoIPstudio extensions is signed A on DIDHub-allocated and DIDHub-ported numbers, materially improving answer rates on mobile carriers that flag B-attestation calls as Spam Likely.
  • Per-DID flat pricing, no commit. $1.99 for a US number, ~$1.10 for German, ~$0.63 for UK London. No monthly minimum, no setup fee, monthly cancellation. Cleaner unit economics than per-seat phone-number add-ons.
  • OBR pricing on outbound. Origin Based Rating means a German DID calling Spain hits the regulated EEA tier; VoIPstudio sees wholesale-grade rates without manual carrier negotiation.
  • Bulk API for fleet provisioning. If you run VoIPstudio across many tenants or sub-accounts, DIDHub’s bulk-allocation API lets you provision hundreds of DIDs per onboarding and bind them to specific tenants programmatically.

Setup steps

  1. Sign up at /signup and provision the DID(s) you want to attach to VoIPstudio.
  2. In the DIDHub dashboard, generate SIP trunk credentials, or configure an IP-ACL trunk if your VoIPstudio account routes from fixed IPs.
  3. In VoIPstudio: open the SIP trunk / BYOC settings under your account’s admin area and add a new trunk pointing at sip.didhub.io with the DIDHub credentials.
  4. Add the DIDs to your VoIPstudio number inventory and route each to the destination extension, IVR entry, or queue.
  5. For outbound: route VoIPstudio outbound through the DIDHub trunk; set Caller-ID to the DIDHub DID assigned to the user or tenant.
  6. Test inbound and outbound; verify STIR/SHAKEN attestation on US/CA calls and audio quality end to end.
