Extentions
“Extension” - is the extension of the telephone line (PBX) or the Centrex system. It works as an association and allows calling to certain telephone sets without the necessity of dialing the telephone number, but only by dialing a short combination of digits, reaching the desired subscriber.
While being a hybrid phone, Gigaset DX800A presents a great investment in the future. Depending on the current office needs it can be configured to work with VoIP, PSTN or ISDN lines, and if necessary the configuration can be changed at any time. The phone supports up to four concurrent calls and up to six handsets, making it an ideal solution for a small office.
