Telephones are used to communicate between distant points. Today's desktop, mobile, and soft phones are equipped with a multitude of functionality to promote communication and collaboration.
ITD provides analog and VoIP telephone services. Analog services are provided only when required for transmission over an analog medium (fax, modem, TDD, etc.). VoIP telephones differ from conventional telephones in that they use the Internet or local data network to transmit the voice signal. Most state agencies currently utilize VoIP telephones.
ITD also installs landlines (physical connections between two telephones or devices) in remote areas where IP service is not available.
