Hi, we have several SPA942s in one of our offices and intend to deploy them in our primary office. The issue that we have is when somebody is on the phone and there is an incoming call, they cannot see that there is an incoming call once they've hung up their existing call. If they're aware that there is an incoming call, they can dial *8 for a call pickup, but they have no way of seeing that 'ringing line'. Any ideas? This system will be hard for people to adapt to after our current NEC line key system Cheers.
