Yes. When used with a non-Cisco phone system, there will be some differences in functionality. First, InformaCast will not send broadcasts to non-Cisco phones. InformaCast will send broadcasts to computer desktops, digital signage, analog overhead paging systems, InformaCast compatible IP speakers, e-mail and mobile phones (via InformaCast Mobile). To trigger a broadcast from a non-Cisco phone system, a SIP trunk must be configured between the phone system and InformaCast. Also, the CallAware feature for 911 alerting will only work on Cisco phone systems. Other than these differences, customers can still use InformaCast Advanced Notification to solve the use cases of intruder alerts, automated weather notification, panic buttons, internet of things integration and more.
