Telephony FAQs

Question 1

How does Telephony integrate with LLM applications?

Accepted Answer

Telephony defines callable tools (like 'voice_call' and 'send_sms') that LLMs can invoke. When an LLM receives a prompt requiring a telephony action, it calls the appropriate tool, executes it via Vonage, and processes the result, allowing LLMs to interact with the real world.

Question 3

What is Telephony (MCP Server)?

Accepted Answer

Question 4

Which LLM frameworks and applications are supported?

Accepted Answer

Telephony is designed for seamless integration with popular LLM frameworks like LangChain and various LLM applications, including Claude Desktop, enabling these platforms to utilize its real-world communication capabilities.

Question 5
