[Asterisk-Users] Queues - calls going to agents lised as "In use"

[Joseph Rothstein]

Grretings to all,

I am having a problem with a customer's queue setup that I don't really
understand.

Background: Customer has 5+ queues and is using dynamic login to the queues
based on SIP/XXX for example. There is a litle script that runs that allows
agents to log into particular queues via the keypad. The user can log in to
any queue that he wants, including multiple queues. The customer is using
Cisco 7940 SIP firmware. Everything works as expected except the following.

When an agent is logged into a queue (one or more), this agent will still
get calls from this queue or even any other queue that the agent is logged
into) even though the agent is shown as "In Use" by Asterisk. The Agent gets
a call waiting beep. I know that call waiting could be disabled on the
phones, but this is not what we want to do. The agent now just ignores the
call waiting beep,and continues working.

I am wondering if this same problem would occur if we were using agents
instead of real extensions. 

Has anyone come up with a solution for this, or know if Asterisk properly
treats Agents who are "In use".

Regards to all.

Joe
