virtual device that can be moved around physical devices... by login and logging out. Queues can contain any type of interface not a point that is partially well put in the Sark we have just got nore in the voi-info website.... It also seams to suggest that Agents are a deprecated feature. AgentLogin. AgentCallbackLogin is depreciated but what has it been replaced by? Not sure what AgentLogin is actually useful for. AgentCallbackLogin in the Management API does not set ${AGENTBYCALLERID_${CALLERID(num)}} I guessing this is a error, fortunatly I've worked out a way to get round it. (setvar) The is no way to log an agent in from the Command Line Interface. AgentLogoff Easy so long as you know the agent id you need to logoff, which means using ${AGENTBYCALLID_${CALLERID(num)}} Queues really have very little to do with Agents as any type of device can be statically on a queue or dynamically added when needed, but the info I've found seams to heavily tie the two concepts together.
