~~Title:DV2000 Envoy~~
====== DV2000 Envoy ======
Envoy is a standalone, middleware application that allows a third-party application to use a simple, standardized rest-based interface over HTTP and web sockets to send data to and receive data from a PMS without having to know all the details of the PMS protocol. On the other side, Envoy connects to the PMS using a TCP socket and can manage the details of the PMS protocol, including low-level activity such as checksum validation, ACK/NAK responses and keep-alive messages that do not need to be passed to the remote client.

===== Features =====
  * Simple REST based PMS interface agnostic of protocol being used.
  * Supports the DuVoice Advanced PMS protocol over TCP client or server link.
  * Supports the Hilton OIAS PMS protocol over TCP client link only.

===== Requirements =====
  * Windows 10 or above.
  * Cannot be installed on DV2000 voice mail systems.
