Niccolo,

This is what I did for one of my clients.  They had a very busy queue, and
were getting annoyed with the Call Waiting beeps.  To resolve this, we
changed the method for contacting the agents to Local Channels.  The local
channel would then do a check (using the GROUP() function) and see if it
was already in a call or not, and if it was, it would delay sending the
call to that agent.  It would then try again after a certain amount of time
had passed.

The agents are added to the queue dynamically using
AddQueueMember(${queue-name},Local/${agent-exten}@agent-calls,,,,SIP/${state-exten}).
 We would load the appropriate variables in the preceding dialplan.

Here's the snippets from extensions.conf:

[agent-calls]
;Context to dial agents when calls come into their queues

exten => _XXXX,1,Wait(1)
exten => _XXXX,n,Set(GROUP()=${EXTEN}-calls)
exten => _XXXX,n,GotoIf($[${GROUP_COUNT(${EXTEN}-calls)} > 1]?wait_longer)
exten => _XXXX,n,Dial(SIP/${EXTEN})
exten => _XXXX,n,GotoIf(${DIALSTATUS}=UNAVAILABLE?wait_longer)
exten => _XXXX,n,Goto(1)
exten => _XXXX,n(wait_longer),Wait(15)
exten => _XXXX,n,Goto(1)
