Buy DID numbers for Cisco CUCM / CUBE — SIP trunk setup with DIDHub
DIDHub provides DIDs and SIP trunking for Cisco Unified Communications Manager (CUCM) deployments via Cisco Unified Border Element (CUBE). Standard CUBE-to-DIDHub SIP trunking with G.711 / G.729 codec support, SRTP for media encryption, and STIR/SHAKEN signing on US/CA outbound.
Why DIDHub for Cisco CUCM / CUBE
- Drop-in CUBE compatibility. DIDHub speaks the SIP profile CUBE expects. Configure DIDHub as an outbound dial-peer with TCP or TLS and you're routing in minutes.
- Per-DID flat pricing for enterprise. Cisco-deployed enterprises typically run on per-seat carrier pricing. DIDHub's per-DID flat economics often beat the bundled-seat math at scale.
- 136-country DID inventory. For multi-country CUCM deployments, DIDHub provisions in 136 countries with dedicated landing pages — broader than most enterprise carriers.
- STIR/SHAKEN A-attestation. DIDHub-allocated US/CA outbound signed A. Compatible with CUCM's outbound Identity-Header pass-through.
- SRTP + TLS support. CUBE-to-DIDHub link can be TLS-encrypted with SRTP media. Enterprise-grade transport security.
SIP trunk setup — step by step
- Sign up at /signup and provision DIDs.
- Generate DIDHub SIP credentials with TLS / SRTP enabled.
- On CUBE: configure a SIP outbound trunk pointing at DIDHub's regional edge. Use TLS port 5061 + SRTP for encrypted transport.
- Set the trunk's Identity-Header pass-through if you're terminating STIR/SHAKEN signed calls.
- Configure CUCM dial-peers / route patterns to direct calls to the new CUBE trunk.
- Test inbound + outbound through CUCM extensions; validate transcoding (G.711 vs G.729) if needed.

FAQ
Does DIDHub work with CUCM directly without CUBE?
CUCM doesn't natively peer with external SIP trunks — you need CUBE (or another SBC) in front. CUBE-to-DIDHub is the standard pattern.
What CUBE codec profiles work with DIDHub?
G.711 µ/A, G.729, OPUS, G.722 are all supported. Configure transcoding on CUBE if your CUCM extensions and DIDHub-side codecs differ.
Can DIDHub replace our existing Cisco-bundled SIP carrier?
Yes — standard SIP trunk migration. Run both in parallel through the FOC window, then cut over.
Is CUBE licensing required?
Yes — CUBE Enterprise (or Hosted) licenses scale per concurrent session. DIDHub doesn't change Cisco's licensing model.
