[Feature Request] Phone node — let Flowise agents call, text, and receive calls

Description

Flowise makes agent-building visual and accessible — but agents can't touch the phone. I build customer-service and sales flows for small businesses, and they all eventually need a phone call: confirm an appointment, follow up with a lead, send an SMS reminder, or answer an inbound call. There's currently no phone node, so those flows either stop at the chat window or require external plumbing.

Proposed

A Phone node in the Flowise canvas:

• Outbound call (script-driven, transcript returned to the flow)
• SMS send
• Inbound call trigger (webhook entry point into a Flowise chatflow)
• Config: phone number, API key, call prompt

Visual example: Customer Enquiry Form → Phone Node → Call lead → Transcript → CRM Update — all in one canvas.

Why now

The telecom layer is fully commoditized — AgentLine (agentline.cloud) is a REST API that provisions real phone numbers for AI agents (~$0.10/min, transcripts + webhooks, no carrier setup). A Flowise node is a small wrapper that unlocks voice for every Flowise user building real-world flows. This would be a genuinely differentiating node for the marketplace.

Happy to help build and test it if the team is interested.
