Reference12r2:Maintenance/Diagnostics/Ping
Automatic pings
Two destinations can be configured which are ping-ed constantly at a configurable interval. Round-trip time is measured for each ping request. The worst round-trip during a one-minute period is written into system counters. The results of the last 24 hours can be examined on Maintenance|Diagostics|Counters (Reference9:Maintenance/Diagnostics/Counters).
Ping
It is possible to execute a ping towards a particular destination host (IP address), since for test purposes it is often necessary to execute a ping command directly from the VoIP device. This makes it possible to check whether a network address (telephone, PBX, VoIP provider, etc.) is accessible. If the remote address is accessible, Reply from <host> is displayed. If the remote address is not accessible, Request timed out is displayed.
