Hi all;;
Is there any way to configure cisco call manager 9.0 and voice gateway to send the line availablity to the IP phone ?
my case as following :
we have installed in our office cisco IP telephony CUCM9.0 VGateway 8FXO lines. sometime when I need to setup a call through the FXO I found all FXOs busy. is there any way send this status to the IP phone so that I can know the line is free now and I can start my call.
