How MIC's Telecoms Numbering Plan, the all-IP PSTN completed in January 2025, the 050/0120/0800 ranges, and the new 060 prefix rollout from July 2026 shape AI voice agents in Japan.
Multimodal agents fuse image, text, and voice in one prompt. We map the 2026 model trade-offs (GPT-4o vs Claude vs Gemini), the cascaded vs end-to-end debate, and the multimodal prompt template CallSphere uses for Salon (uploaded hair photos) and Real Estate (listing PDFs).
Anthropic claude sonnet 4.5 bedrock: infrastructure-level look at Anthropic AWS Bedrock, including cloud AI partnership, deployment topology, region availability, and cost considerations.
A practical engineering deep dive into Claude skill authoring, covering architecture, tradeoffs, and what production teams need to know about agent development.
What ChatGPT Operator 2.0's developer API actually costs and supports in production — task templates, scheduled runs, and where it beats Browserbase.
Why NATS 2.14 became a credible alternative to Redis pub/sub for WebSocket fan-out in 2026: native browser support, JetStream durability, and how it wires into AI agents.
How AI receptionists handle E911 in 2026: ANI/ALI delivery, dynamic location with PIDF-LO, Kari's Law, RAY BAUM'S Act, and the operational checklist.
FreeSWITCH's mod_audio_fork (and its sibling mod_audio_stream) sends L16 PCM over WebSocket to your AI engine and receives audio back. Here is the production pattern in 2026.
Twilio Alpha MCP server exposes the SMS/voice/WhatsApp surface to agents. We cover ConversationRelay, the voice-call MCP pattern, and how CallSphere uses it across 37 specialist agents.
