It is possible that Incoming calls, instead of get answered by the system, stay Ringing until one answered ?
I had made this in astlinux doing this in extensions.conf
exten => 3199xxxx,1,Ringing()
exten => 3199xxxx,n,Dial(SIP/9900&SIP/2222&SIP/1000,120,tThHKr
but in freepbx I do not how to make all incoming calls only ring without answer until one attendant answered
thanks for your info
