Exclusive Routing Tiers
Two dedicated route profiles engineered for the highest-quality conversational traffic in the US wholesale voice market.
USA Manual Direct
Engineered strictly for human-to-human conversational dialing — BPO call centers, high-touch outbound sales teams, and customer service operations.
- 100% Clean Local CLI Guarantees proper STIR/SHAKEN attestation so outbound calls display legitimate local caller IDs without "Spam Likely" flags on major US carriers including AT&T, Verizon, and T-Mobile.
- High ASR Optimization Direct Tier 1 termination bypasses multi-hop transit carrier spam filters, maximizing Answer-Seizure Ratio and ensuring your agents spend more time talking, less time waiting.
- PQ1 Hardware Priority Strict Priority Queue 1 allocation on carrier-grade routers ensures real-time packet delivery without jitter, echo, or audio cutouts during live conversations.
Conversational AI & IVR
Engineered specifically for AI voice agents, dynamic conversational bots, automated customer intake, and interactive voice response systems.
- Uncompressed G.711 Codec Crystal-clear bidirectional audio stream with 0% packet loss for accurate Speech-to-Text transcription, NLP processing, and real-time sentiment analysis.
- Precision DTMF Relay Full RFC2833 out-of-band touch-tone signaling support prevents digit distortion, ensuring accurate menu navigation for IVR systems and automated call flows.
- Ultra-Low Latency Direct carrier handoff minimizing round-trip delay below 150ms, keeping conversational voice AI responsive and natural-sounding during dynamic dialogues.
Carrier-Grade Architecture
Every call traverses enterprise-grade infrastructure with strict quality-of-service guarantees from ingress to termination.
Strict Traffic Integrity Policy
To maintain pristine IP reputation and protect our Tier 1 carrier interconnections, this route is strictly closed to automated predictive dialers, high-CPS blasts, and "Press-1" robocalls. All accounts are algorithmically monitored at the softswitch layer for healthy ASR and ACD thresholds. If you run legitimate conversational traffic or compliant IVR, your calls will never share bandwidth with toxic telemarketing traffic.
Frequently Asked Questions
What is Tier 1 Voice Termination?
Tier 1 voice termination means your SIP traffic is handed off directly to a Tier 1 US carrier backbone — such as AT&T, Verizon, or Lumen — without passing through intermediary transit carriers. This eliminates multi-hop latency, reduces call failure rates, and ensures clean caller ID display with full STIR/SHAKEN A-attestation compliance. Unlike Tier 2 or Tier 3 routes that aggregate traffic through multiple providers, Tier 1 termination gives your calls the highest possible priority and quality on the US PSTN network.
What does Clean CLI mean in wholesale VoIP?
Clean CLI (Calling Line Identification) means the outbound caller ID is displayed correctly on the recipient's phone without being flagged as "Spam Likely" or "Scam Likely." This is achieved through direct carrier interconnections and STIR/SHAKEN attestation, ensuring calls appear as legitimate local numbers. For BPO call centers and outbound sales teams, clean CLI is critical because flagged numbers dramatically reduce answer rates and damage brand reputation.
What traffic types are accepted on these routes?
We exclusively accept manual conversational traffic from BPO call centers, legitimate outbound sales teams, customer service operations, appointment setting, debt collection (FDCPA-compliant), and compliant conversational IVR and AI voice agents. Automated predictive dialers, high-CPS blasts, robocalls, and "Press-1" campaigns are strictly prohibited. All accounts are monitored for healthy ASR (Answer-Seizure Ratio) and ACD (Average Call Duration) thresholds to ensure route quality.
How do I get started with a test trunk?
Contact our traffic management team directly via Telegram (@Me_ryker) or WhatsApp (+1 267 243 1476 or +1 918 777 0984). We will provision test IP credentials and a free interconnect trial so you can verify ASR, audio quality, and CLI presentation on your own softswitch before committing to production volume. The entire onboarding process typically takes less than 24 hours.
What is PQ1 Priority Queuing and why does it matter?
PQ1 (Priority Queue 1) is the highest hardware-level QoS (Quality of Service) classification on carrier-grade routers. Voice packets tagged PQ1 are processed before all other traffic categories, ensuring sub-150ms end-to-end latency, less than 30ms jitter, and zero packet loss. This is critical for real-time voice conversations where even small delays cause crosstalk and awkward pauses, and especially important for AI voice agents that depend on low latency for natural-sounding real-time dialogue.
Do you support SIP over TLS encryption?
Yes. Our infrastructure supports SIP signaling over UDP, TCP, and TLS (Transport Layer Security). For carriers and BPOs with compliance requirements like PCI-DSS or HIPAA, we recommend SIP-TLS for encrypted signaling. Media encryption via SRTP is also available upon request during interconnect provisioning.
