Figure 1. Technological resources used to implement remote care.

Legend: Provision of IP extensions (digital telephone system that uses the internet protocol) specific to provide care with all the features of integral recording of calls by means of a digital telephone exchange (Digital PABX). For professionals who were doing the work remotely, extensions were set up directly on the personal computer, using a multimedia softphone application. In order for this professional to access the IP telephony resource, a virtual private network connecting to the digital PABX Server, called VPN or “Virtual Private Network”, was set up. Access to the Clinical Hospital System (Tasy) was also made via VPN connection for professionals who were working remotely. In the Hospital Clinical System, classifications were created in the diaries to identify the phone calls.
