I have a very similar need. We are using call queues and would like to
have only 1 call presented to our trouble call reps at a time, but would
like to give them the ability to initiate an outgoing call on a
different line (even while on an incoming call). We are using Aastra
480i SIP phones. 

I have read that app_groupcount and setgroup may be the way to handle
this but the wiki is confusing.

Can someone suggest an approach (preferably one currently in use)? We
are using Asterisk 1.4.17.
