What is DIDHub? ​

DIDHub is a B2B virtual phone number and SIP-trunking platform. We provide real, locally-dialable phone numbers (DIDs) in 130+ countries — geographic, mobile, and toll-free — delivered to your VoIP, PBX, Microsoft Teams tenant, or AI voice agent over standard SIP.

If you're building voice infrastructure, automating telecom workflows, or just need a UK / US / EU number that doesn't tie you to a specific provider, you're in the right place.
