Agent Group

Hi Experts,

Having difficult time with Agent Group defined in agents.conf.

I have defined group 1 & 2 in agents.conf then assigned the group in the queues.conf to the specific queue. Phone able to login to particular group agent but queue status shows unavailable and no call transfer to that queue.
Here is my conf:

Agents.conf

[agents]
agent => 2001,4321,Test1
agent => 2002,4321,Test2

group=1
agent => 2004,4321,Test4
agent => 2005,4321,Test5

group=2
agent => 2006,4321,Test6
agent => 2007,4321,Test7

Queues.conf

queue1 ; standardQueue is the template
member => Agent/2001
member => Agent/2002

queue3
member => Agent/2003

queue4
member => Agent/@1

Not sure where is the issue. Any advice?

Thank You
