[asterisk-users] sip busy detect

[satish patel]

Hi, 

I am trying to configure busy detect on sip channel but somehow its not working may be this is my mistake could you please help me to figure out. I have added following options in my sip.conf 

 [7527]
type=friend
context=from-sip
host=dynamic
dtmfmode=rfc2833
callerid="Guest" <7527>
mailbox=7527 at default
nat=no
qualify=yes
cc_agent_policy=generic
cc_monitor_policy=generic
busylevel=1
limitonpeers=yes
call-limit=1

when 7527 is busy i am getting following error message on CLI. Why i am getting channel status CONGESTION ? instead BUSY ? 

 [May  2 16:47:31] NOTICE[31757]: chan_sip.c:5658 update_call_counter: Call to peer '7527' rejected due to usage limit of 1
    -- Couldn't call 7527
    -- Called 7527
 == Everyone is busy/congested at this time (1:0/1/0)
 -- Executing [s at macro-stdexten:2] Goto("SIP/7604-00000006", "s-CONGESTION,1") in new stack
    -- Goto (macro-stdexten,s-CONGESTION,1)
