The Clarity 4020 GSB VoIP Phone with built in GSM is the initial building block in the Clarity phone system concept. The Clarity 4020GSB can be used as a stand alone telephone and will connect to a standard analogue telephone line, as well as accepting a standard mobile phone SIM Card (Vodafone, O2, T-Mobile & Orange) and can be used to make and receive calls using PSTN, GSM and VoIP (SIP Trunks). All that is required to expand the system is to add extra Clarity IP Phones to your Local Area Network / Network Switch / Router. The Clarity 3020 will then be able to make, receive and transfer calls using any of the telephone lines connected to the Clarity 4020. The system will accomodate a maximum of 16 extensions, 7 SIP Trunks, 1 Analogue phone line and 1 SIM Card.
