45 * cut, a basement, or a tower handover, and those outlast two minutes routinely. Five minutes
46 * is the difference between resuming the lesson and rejoining it. Measured cost of getting
47 * this wrong: 240 reconnects across 90 calls already succeed, so the SDK's own retry is the
48 * mechanism that works and this only widens the window it is allowed to work in.
