asterisk users - Jun 2005 - inbound agent recording filename

We upgraded to cvs-head a couple of days ago, but haven't changed the 
config files at all.

Prior to the upgrade, all inbound calls to our call queues were 
recorded, and the filename was like "agent-6043-1109793719-24472.gsm".
After the upgrade, the filename is now "1109793719-24472.gsm"

What do I need to change, (or can I) to get back to the "old" naming 
convention - it was really useful to see the agent number as part of the 
filename.

Help :)
