[Freeswitch-users] callcenter_config commands

Hi, I found the following useful commands in mod_callcenter module. callcenter_config queue list agents [queue_name] [status] callcenter_config queue list members [queue_name] callcenter_config queue list tiers [queue_name] callcenter_config queue count agents [queue_name] [status] callcenter_config queue count members [queue_name] But when I run the following command, it says simply "+OK" and no members list even though there are calls in queue1. => callcenter_config queue list members queue1 I am using FreeSWITCH Version 1.0.head (git-8f2ee97 2010-12-05 17-19-28 -0600). Should I have to use any latest version? regards rajkumar k
