21. Applications of IRIS IVDX IP PBX

22. Multi-locational offices : With IP at the core and Coral’s feature rich media gateways acting as remote switches, communication of entire organisation can be controlled from one central location. A lot of resources, such as Voice mail, CDR etc can be shared resulting in reduced cost of ownership for the entire communication networks. Mission Critical applications : IRIS-IVDX IP PBX has the option of a disaster recovery (DR) server which can be located at geographically distant location. This “DR server” takes over and functions as a CPU when both main and HSB server at the principal location fail. A very useful application for defense forces and mission critical applications. Applications………

23. Large and Medium Corporates : IRIS IVDX IP PBX allows you to migrate from your current TDM environment to hybrid TDM/IP environment seamlessly. With the option of Unified Messaging platform you can manage your voice mails / e-mails and faxes from your 'customised user portal'. You also have an option of using hard and soft phones which give you a variety of features at the touch of a button. Railways : With main server at the HQ location and smaller media GWs at every station, IRIS-IVDX IP PBX serves as a perfect IP hybrid platform with pure soft switching environment at the HQ and IP/TDM environment at stations, all controlled from a central location. Applications………

24. Call Centers: With built in ACD functionality and IRIS-IVDX IP PBX ability to work on standard SIP protocols, the system behaves like a well integrated solution with IP based predictive dialers / loggers and CDR softwares available in the market. Existing Coral Customers : If you are an existing customer of Coral using our TDM based IRIS-IVDX, check with us to know, how you can migrate to a IP environment while protecting your investment in the legacy network. You could even migrate to have a “Fixed Mobile Convergence” where your mobile phone will become an extension of your office PBX as you walk into your office. Applications………
