Neutral infrastructure
Strengthen the call path without replacing the product, models, and customer experience that make your company valuable.
Built for voice-dependent products
Your product needs telecom. Your team does not need to become a telco
HD Carrier gives AI builders, contact centers, communications platforms, carriers, and MVNOs one direct aggregation point for high-quality voice paths into major US mobile networks.
01 / AI and application builders
Give every model a better signal and more conversation time
If your AI service needs to dial in or dial out, the infrastructure underneath it matters. Keep the agent, orchestration, ASR, TTS, and workflow while HD Carrier supplies the direct telecom layer.
- Reduce avoidable transport delay on supported routes
- Preserve more speech detail with AMR-WB
- Connect through one carrier aggregation point
What improves
Natural turn-taking
Fewer intermediary hops leave more of the real-time response window available for inference, orchestration, and speech generation.
Higher-quality input
Wideband audio gives people a more natural conversation and speech systems a clearer source signal for recognition and analysis.
02 / Contact centers and enterprises
Make the route as dependable as the people and systems on the call
Customer outcomes depend on clarity, identity, and consistent delivery. Direct routing improves the network layer underneath service, sales, support, and regulated conversations.
- Inbound and outbound SIP calling
- Failover or weighted round-robin routing
- Preserved STIR/SHAKEN information
What improves
Route consistency
Eligible calls use a direct on-net path instead of moving through a changing chain of secondary carriers.
Call integrity
A known IP path and preserved attestation data give downstream systems stronger provenance for trust decisions.
Enterprise traffic patterns
Trunk groups support multiple endpoints, failover priorities, and distribution across your application infrastructure.
03 / Carriers, CPaaS providers, and MVNOs
Premium US mobile reach without rebuilding every interconnect
Extend a carrier, CPaaS, or subscriber product into the US through a direct ecosystem reaching more than 405 million mobile devices.
- Direct paths including AT&T, T-Mobile, and Verizon
- HD codec support and transparent interoperability
- Portal or API-based provisioning
What improves
One aggregation point
Connect existing SIP infrastructure once and evaluate premium routes across the participating mobile ecosystem.
Carrier-ready architecture
Use endpoints, trunks, trunk groups, DIDs, and APIs instead of creating a complete carrier operations layer inside the product team.
Qualification and trust
Company and traffic review protects legitimate customers and the network before telecom resources are issued.
Where the path carries extra weight
Conversational quality matters across high-trust workflows
Healthcare, financial services, insurance, and government teams often scrutinize call identity, speech clarity, and network behavior. HD Carrier provides a more controlled route to evaluate without implying unverified compliance certification.
Healthcare Clearer patient, member, and care-team conversations
Financial services Identity-sensitive customer and account workflows
Insurance Speech-led service, claims, and policy interactions
Government Consistent public-facing voice access
