[asterisk-users] Agent auto congesting

[rachid]

Hello,

I Have an agent on a queue, evry thing works normally, but after a time 
(about 5 minutes) my
agent is pauses (agent is still regitred but can't takes calls),  on 
Astrisk  console i have the message :

[Jun 20 11:55:12] NOTICE[8803]: chan_sip.c:2757 auto_congest: 
Auto-congesting SIP/anna-08215f68
    -- SIP/anna-08215f68 is circuit-busy
    -- Nobody picked up in 8000 ms

I think that my agent will be busy after a timeout.!!!!!!!!!!!!!!, why 
?, and how can 'i modify this timeout???

If you have any idea to resolve this problem, thanks to write me.
