[asterisk-users] only ring phones that are not on a call

[Danny Nicholas]

You could set up a hint for the extension and check the hint for "inuse"
before executing the Dial in your dialplan

Exten => 801,hint,SIP/100

Exten => XXX,1,System("/usr/sbin/asterisk -rx "core show hints"|/bin/grep
SIP/100|/bin/grep InUse
Exten => XXX,2,GOTOIF($["{CMSTATUS}" = "FAILURE"])?dial
Exten => XXX,3,hangup() 
Exten => XXX,4(dial),Dial(SIP/100)
Exten => XXX,5,hangup()

Subject: [asterisk-users] only ring phones that are not on a call

is there anything i can do in my dialplan to only ring phones which are not 
on a call at the time someone dials in?

its for a call center, they do not want to use queues, but they are 
complaining that the call waiting beep is annoying.

i tried call-limit in the sip.conf but then it just busy out all phones when

a call comes in.

any thoughts?

thanks,
jon
