Memory & personalization

Voice MCP records durable per-caller memory after each call and greets a known caller with a cross-session recall line that picks up where you left off.

Voice MCP remembers who it has talked to. Each call leaves a durable memory, and the next call opens by recalling it.

Memory is recorded after the call

When a call ends, Voice MCP records a durable memory for that caller. The write happens after the call, off the request path, so it never slows down the live conversation.

Recorded post-call, off the hot path

Memory is captured once the call completes, not mid-turn. This keeps each spoken turn fast while still building up a durable per-caller record over time.

Known callers get a recall greeting

When a recognized caller phones back, the agent builds a cross-session recall line into the greeting — a short "last time we looked at Acme…" style opener that references the prior conversation, so the caller doesn't have to re-establish context from scratch.

Continuity across calls

The recall line turns a series of separate phone calls into one continuous thread — the agent picks up roughly where the last call left off rather than starting cold.
