SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you design and sanity-check phone-call products without assuming the app itself can control carrier-level routing. It is useful when you need to understand what is possible across carrier forwarding, CPaaS numbers, caller ID, and mobile OS constraints.

Core Features & Use Cases

  • Carrier and routing analysis: Distinguishes SIM-level, forwarded, ported, and CPaaS-controlled numbers so you can choose the right call flow.
  • Platform constraint checking: Clarifies what iOS and Android can and cannot do for caller ID, blocking, and native call handling.
  • Product architecture guidance: Helps plan spam screening, voicemail replacement, AI receptionist flows, and shield-number setups with realistic tradeoffs.
  • Use Case: A team building an AI answering service can use this Skill to decide whether to rely on conditional call forwarding, port a number to a provider, or use a secondary eSIM for faster launch.

Quick Start

Ask for a telephony architecture recommendation for your call product, including carrier routing limits, iOS and Android constraints, the main blocker, a ship-fast option, and a long-term option.

Frequently Asked Questions about telephony-product-architecture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design a telephony architecture for an AI call handling product?▼

To design a telephony architecture for an AI call handling product, you must separate carrier routing, OS APIs, and provider webhooks to choose between conditional call forwarding, CPaaS numbers, or number porting based on feasibility.

Can I use conditional call forwarding for an AI receptionist or do I need to port my number?▼

You can use conditional call forwarding for an AI receptionist to launch quickly, but porting your number to a CPaaS provider offers better long-term control by eliminating carrier routing dependencies and forwarded call delays.

What are the iOS and Android constraints for native call handling and caller ID?▼

iOS and Android native call handling constraints limit how apps manage caller ID, call blocking, and device setup flows, requiring you to separate OS APIs from carrier routing and provider webhooks for reliable mobile call integration.

How does CPaaS number routing work for spam screening and voicemail replacement?▼

CPaaS number routing works for spam screening and voicemail replacement by intercepting calls through provider webhooks, allowing you to apply current-source verification and AI logic before connecting or dropping the incoming call.

What is the best way to set up shield numbers or honeypots for call screening?▼

The best way to set up shield numbers or honeypots for call screening is to use CPaaS-controlled numbers that separate carrier routing from device setup flows, enabling reliable caller ID verification and spam detection without app-level carrier control.

Why does my mobile call integration fail to control carrier-level routing?▼

Mobile call integration fails to control carrier-level routing because apps cannot natively modify SIM-level forwarding or ported number flows, requiring you to route calls through CPaaS webhooks or secondary eSIMs for reliable product architecture.
