Buy DID numbers for OpenSIPS — SIP trunk setup with DIDHub
OpenSIPS is an open-source SIP server / proxy / class-5 application server used by carriers, ITSPs, and large CPaaS operators. DIDHub provides the DIDs and the upstream SIP interconnect; OpenSIPS handles your routing, billing, and class-5 logic on top.
Why DIDHub for OpenSIPS
- Standards-only SIP. DIDHub speaks plain RFC-3261 SIP. No OpenSIPS-specific modules needed beyond the ones you'd use for any upstream peering (
dispatcher,load_balancer, etc). - Per-DID flat pricing. Predictable economics for OpenSIPS-fronted deployments. $1.99 for a US number, no commits.
- 136-country DID inventory. Pull DIDs anywhere DIDHub supports them and route through your OpenSIPS configuration.
- STIR/SHAKEN A-attestation. DIDHub-allocated US/CA outbound signed A by default.
- Carrier-grade interconnect. DIDHub uses tier-1 wholesale carriers and operates SBCs at carrier-neutral colocations — the kind of upstream OpenSIPS deployments expect.
SIP trunk setup — step by step
- Sign up at /signup and provision DIDs.
- Generate DIDHub SIP credentials.
- In OpenSIPS: configure DIDHub as an upstream peer in
dispatcheror your routing logic. - Set up registration / IP-allowlist depending on auth method chosen.
- Wire main routing to send inbound DID calls to downstream PBXes / customers and route outbound through DIDHub with proper Caller-ID.
- Test inbound + outbound; validate STIR/SHAKEN, audio quality, and registration if used.

FAQ
How does DIDHub differ from being one of N upstream carriers in my OpenSIPS dispatcher?
DIDHub is happy to be one of N. We're carrier-grade with regional SBCs — many large OpenSIPS deployments use DIDHub alongside other upstream peers in least-cost-routing or failover groups.
Can I do per-customer DID allocation programmatically?
Yes — DIDHub's REST API supports per-customer DID provisioning at scale. Common pattern: OpenSIPS handles routing, DIDHub API handles DID inventory + porting.
Does DIDHub work with OpenSIPS + RTPproxy for media?
Yes. The media plane is your choice; DIDHub speaks SIP and SRTP.
Is there a discount for high-volume OpenSIPS deployments?
Per-DID pricing is flat at any volume, but for very high outbound minute volumes (>500K min/mo), talk to sales for a wholesale per-minute deal.
