A fundamental recommendation for any Hotel considering a Cloud/Hosted solution is the use of a Service-Call local survivable gateway. This combination of Cloud with on-site failover options is often referred to as a hybrid solution. Should an internet/connectivity failure occur with the Hotel phones, including resident’s analogue or SIP/IP room phones, failover to the local gateway ensures communication within a Hotel is maintained. Alternative solutions for Internet access or traditional ISDN services can also be applied to retain external access.
