Questions
What is the difference between Wixzel Voice and IntelliCallAI?
Wixzel Voice is a hosted API and MCP server for building your own AI agents that place and answer phone calls, paid per second from prepaid credit. IntelliCallAI is a finished, self-hosted, white-label AI voice-calling platform that you buy once and run on your own server. Both are made by Wixzel.
Which Wixzel voice product should a developer use?
A developer adding voice to their own product should use Wixzel Voice: it is an HTTP API with TypeScript and Dart SDKs and a realtime API for web and mobile apps, with one API key and one prepaid balance for every voice engine.
Which Wixzel voice product should an agency use?
An agency that wants to sell AI calling to clients under its own brand should use IntelliCallAI with the Extended license, which allows rebranding it and running it as a paid service. The Regular license does not allow reselling.
Can Claude or ChatGPT place phone calls with a Wixzel product?
Yes, with Wixzel Voice. Its MCP server lets Claude, ChatGPT, Cursor or another MCP client set up an agent and place real calls over your own SIP trunk when you ask. IntelliCallAI has no MCP server.
Does either Wixzel voice product sell phone numbers?
No. Wixzel Voice runs over your own SIP trunk, and IntelliCallAI uses your own Twilio account or SIP trunk. Neither sells numbers or resells minutes.
Can I self-host Wixzel Voice instead of IntelliCallAI?
Yes. Wixzel Voice has a $499 self-hosted license that runs the API, MCP server and console on your own server for your own business. It does not allow hosting it for other businesses; for reselling, IntelliCallAI's Extended license is the one to use.
