Fair Usage Policy (FUP)
Guidelines regarding concurrent channel capacities, call setup pacing (CPS), pulse calculation metrics, and cloud compute utilization across our carrier telephony fabric.
Ensuring Carrier Stability & Quality of Service (QoS)
Our network processes tens of millions of voice minutes across tier-1 Indian telecom operators (Airtel, Jio, Vi, Tata Teleservices). To prevent network switch congestion and ensure crystal-clear sub-40ms voice latency, traffic injection must conform to purchased concurrent channel ceilings and carrier signaling limits.
Concurrent Channel Allocation & Over-Subscription
Each SIP trunk or virtual number is provisioned with a specified number of Concurrent Calling Channels billed on a monthly basis (at ₹240 / channel / month). A single channel allows one active inbound or outbound voice session at any given instant.
- Channel Ceiling: When your simultaneous live calls reach 100% of your subscribed channel capacity, any additional incoming callers will receive standard carrier busy signaling (SIP 486 Busy Here) or will be queued in your IVR according to your configured overflow logic.
- Burst Allowance: Enterprise accounts with dynamic burst enabled may temporarily burst up to 20% over their base channel tier during unexpected inbound surges, billed at standard on-demand burst rates.
Calls Per Second (CPS) Pacing Rules
To safeguard PSTN switches from SIP signaling packet storms, automated dialers and API campaign triggers must honor our automated CPS pacing:
Initiating calls faster than the provisioned CPS will trigger rate-limit responses (HTTP 429 Too Many Requests / SIP 503 Service Unavailable).
Call Pulse & Duration Calculation
Voice minutes are metered based on standard Indian carrier pulse protocols:
- Standard Pulse: Voice minutes in prepaid minute packs are billed in 60-second pulses. Any call fraction under 60 seconds is rounded up to the nearest 60-second block once the call is connected (SIP 200 OK).
- Unanswered & Failed Calls: Calls resulting in Busy, Unreachable, Ringing No Answer, or Congestion are not billed against your minute balance.
- All-Inclusive Scope: Our Voice AI minute pack rate (₹5.00 / ₹4.50 / ₹4.00) includes PSTN carrier termination, Speech-to-Text (ASR), real-time LLM cognitive inference, and Text-to-Speech (TTS) voice generation with zero per-seat surcharges.
Short Duration Calls & Answer-Seizure Ratio (ASR)
Carriers enforce strict network health metrics to mitigate robocall spam:
Accounts that repeatedly breach these thresholds will be automatically transitioned from shared PRI pools to isolated enterprise trunks with mandatory outbound throttling.
AI Model Concurrency & GPU Resource Management
To maintain ultra-low conversational latency (<450ms turnaround), accounts with high concurrent speech volume (over 100 simultaneous streams) must coordinate with 7Silicon Group NOC engineers for dedicated GPU cluster warm-up and regional edge deployment across Mumbai, Pune, or Bengaluru data centers.
