Understanding TelePresence E911 IP Phone Support
You can use a Cisco IP phone as a user interface in a Cisco TelePresence System. See in Figure 1. In this
configuration, the IP phone must always be on and available for emergency calls. If the power to the
codec in the Cisco TelePresence System fails, is disrupted or if the codec fails, the IP phone is not
available.
