We use it for sales.. but have never thought about implementing that.. in what way would you do it?

It might make a good plugin. That way you could have a different round robin for each department. 

You might need several staff working on a specific "topic" of ticket for each department.. you could implement a custom ticket-filter to do it.For instance, you could create a new team "sales-rr", "sales-queries-rr" for each "round-robin queue" and add the staff to it, then keep the last assigned staff member per queue in a variable somewhere, whenever you get a new ticket for a team ending in -rr, simply check the appropriate list, find the next member and assign the new ticket to them.. could work.

// psuedocode..

$ticket; // should be available to a ticket-filter, might not be called this.

$queue_name = $ticket->getTeam;

// see if team/queue name ends in -rr otherwise don't use round-robin system.

if (substr_compare ( $queue_name, '-rr', - 3, strlen ( $queue_name ) ) === 0) {

$team = new Team ( $ticket->getTeamId() ); // generally.. needs work!

// check the last assignment

$last_assignment_id = db_query (); // ... SELECT rr_queues_$queue_name FROM My_VARS .. or something

$assign_to_next_staff_member = false;

$members = $team->getMembers();

foreach ( $members as $staff ) {

if ($assign_to_next_staff_member) { //if this is the one immediately following the last assigned staff, use it!

assign_ticket($ticket,$staff);

break;

}

if ($last_assignment_id == $staff->id) {//check each staff in team to see if they were the last one assigned a ticket

$assign_to_next_staff_member = true;

}

}

if(!$ticket->isAssigned && $assign_to_next_staff_member){

//last member of team was assigned for the last ticket, assign to first staff member.

assign_ticket($ticket,$members);

}

if(!$ticket->isAssigned()){

$ost->logError('Failed to assign ticket to round-robin queue ' . $queue_name, 'Ticket: ' . $ticket->id);

}

}

function assign_ticket($ticket,$staff){

$ticket->assignToStaff ( $staff, 'Auto-Assigned by round robin' );

db_query (); // update myvars... save the $staff->id to the table..

}
