Hi @Madhav_SR Welcome!
Good concept! To handle lengthy customer phone calls, you don’t require a “stronger” memory but rather a better pattern. While using n8n, it’s advisable to use a Memory Manager, as well as a Window/Buffer (or Simple) Memory node. Further, do pass a stable session ID from your webhook, for instance, call ID/user ID, so that each caller retains his history. In this manner, Gemini only sees the past turns or a summary instead of one huge prompt which works much better for lengthy voice conversations.

@Madhav_SR Once memory is turned on, the tools fail because Simple Memory does not identify the “conversation” each webhook request belongs to. In the Simple Memory node, configure Session ID > Define and point it to a stable value from your webhook body (for instance {{$json.body.sessionId}} or a call/user ID sent by 11labs). For a quick check, you can try hard coding “test-session1” there. If the error goes away, then you just have to pass a real per-caller ID from the webhook. After the session ID has been set, you can re enable Simple Memory, and your voice agent should not break the tools and keep context. And when asking questions in the forum next time share your proper context and error with workflow that would help everyone to assist you.
