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@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
