Yes @Amin VZ longer 45–60 min calls can definitely be stable, but the main challenges are usually memory/context handling, latency buildup over time, reconnection handling, audio drift, and managing interruptions naturally during long conversations. A lot also depends on the stack you’re using (LiveKit, Twilio, VAPI, Retell, etc.) and how the agent handles context compression and streaming over extended sessions. I’ve worked on long-session voice setups before and can help share some best practices if needed.
