This read-write Integer32, in milliseconds from 1 to 10000, is the request timeout the XGCP protocol waits before retransmitting an unacknowledged signaling message, with the requesting entity responsible for retrying commands whose timeout has been exceeded. Admins tune it because too short a value causes needless retransmissions on a healthy but slower network, while too long delays recovery from lost messages. For example, on a WAN-connected gateway with higher latency to its call agent, an admin might increase this timeout to avoid unnecessary retransmission storms.
