Frequently asked questions
Can I make calls and send SMS through the AI agent?
Yes. Make outbound calls with destination number and track status. Send SMS messages to any contact with delivery tracking. Use contact management tools to find recipient numbers.
Does JustCall require two credentials?
Yes. JustCall uses an API Key and API Secret pair for authentication. Both are sent as Bearer credentials against api.justcall.io/v1.
Can I listen to call recordings and track agent performance?
Yes. Access call recordings with duration and metadata. Monitor agent call volumes, average handle time, and availability status.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call JustCall tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
