asterisk users - Dec 2012 - queues show some agents "(In use)" from the start

Hi gurus
Some of my agents  are "in use" with no call involved.


   Members:
      Local/0971230031 at internal/n (In use) has taken no calls yet
      Local/0972105500 at internal/n (In use) has taken no calls yet
   No Callers


Is there a workarround so solve this?
Wham am i doing wrong?

If i change agent "Local/0971230031" for an other mobile line....
works
fine :(


This is my config
Asterisk 1.6.1.6
DAHDI Version: 2.6.1
libss7 version: 1.0.2

queues.conf
[RCEN]
musicclass = default
strategy = rrmemory
weight=0
wrapuptime=15
autopause=no
setinterfacevar=yes
setqueueentryvar=yes
setqueuevar=yes
eventwhencalled = yes
ringinuse = no
joinempty=yes
member => Local/0972105500 at internal/n
member => Local/0971230031 at internal/n
