Thanks very much - I am using FreePBX 2.6.0 on Asterisk 1.4 - the Queues module thankfully did the job perfectly. I need to configure quite a bit on our current configuration of how we handle our inbound calls at different times of the day etc but now that you sent me towards a solution I have a good incentive to get this work done.
Much appreciated and once again, sincere thanks for a very prompt response.
Best wishes
Andy
