Using dynamic agents on any asterisk based system can be a struggle. First, the phone digit maps or dial plans have to allow the login/logout commands like queue*extension# for logging in and queue**extension# for logging out.

Also, asterisk allows you to log into a queue with any extension, including system extensions. We’ve seen people log into a queue with extension 2 which ends up causing calls into that queue to go into an infinite loop.

The following code was originally found here: http://fonality.com/trixbox/forums/trixbox-forums/open-discussion/howto-dynamic-agents-login-logout-auto-loggoff but since it seems like they’ve locked the thread i’ll post my changes here.

[custom-agent-inout]
exten => s,1,Wait(1)
exten => s,n,Set(CALLBACKNUM=${CALLERID(number)})
exten => s,n,AddQueueMember(queue1,Local/${CALLBACKNUM}@from-internal/n)
;If they’re already logged in, log off
exten => s,n,GotoIf($[“${AQMSTATUS}” = “MEMBERALREADY”]?a2)
exten => s,n,Playback(non-crisis-login)
exten => s,n,UserEvent(Agentlogin,Agent: ${CALLBACKNUM})
exten => s,n,Hangup()
exten => s,n(a2),RemoveQueueMember(queue1,Local/${CALLBACKNUM}@from-internal/n)
exten => s,n,UserEvent(Agentlogoff,Agent: ${CALLBACKNUM})
exten => s,n,Playback(non-crisis-logoff)
exten => s,n,Hangup()

The only thing we’ve changed was AddQueueMember(${ARG1}) to AddQueueMember(queue1,Local/${CALLBACKNUM}@from-internal/n).

This caused the correct trixbox interface to be added to the queue. Just passing the extension number to AddQueueMember caused the extension to ring but would not follow any of the queue rules such as skip busy agents.

We’ve also expanded on this to log agents into multiple queues at the same time. This was necessary since for some calls, we’ll allow the caller to wait in a queue for a little bit, then direct them to an IVR for the chance to leave a message, then back into a second queue with music to hold for an agent.
