Still prefer to use traditional products such as Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN)? Evantage Technology can help you acquire these systems specific for your business needs.
PSTN & ISDN provide a lot of flexibility when it comes to using EFTPOS, internet or fax lines. For additional lines, PSTN & ISDN also automatically transfer calls to the remaining lines when a present number is being engaged.
This alternative flow of calls through PSTN and ISDN will allow a specialised connection between two callers specially for that call.
