Is there any way under software control (CLI, Manager, etc.) to "busy out" one or more PRI channels, for testing purposes, without actually having to make real calls on them? It should have the following effects: a) Outgoing calls will not try to use the busied out channels, when using a group specifier. An attempt explicitly to dial via a busied channel would fail with CHANUNAVAIL. b) The remote switch would recognise the channels as busy and would hunt for a non-busy channel when attempting to place a call to the system. The intention is to simulate behaviour as a system approaches capacity, not in terms of loading but of routing, etc. Cheers Tony -- Tony Mountifield Work: tony@softins.co.uk - http://www.softins.co.uk Play: tony@mountifield.org - http://tony.mountifield.org
