asterisk users - Aug 2006 - Asterisk queues and dynamic members

Hi All

I have set up queues in Asterisk to use dynamic members using the 
addqueuemember application.  The application works well, but I have one 
issue with it; Asterisk keeps passing a waiting caller to a member even 
if the member is on a call from the queue already.  Surely Asterisk 
should know that the agent is busy on a call and try another free 
agent?  I have worked around this by using call-limit=1 in the sip.conf 
file.

Kind Regards
Garth
