Service providers need only to provide a minimum of one SIP number to each subscriber. Billing and service deployment are simplified by allowing subscribers to use two phones with the same SIP number. If one telephone is in use, users may use a secondary telephone to place a call while using the same SIP number. Additionally, users may also receive incoming calls even when the SIP number is in use. The advantages include increased traffic and service revenue. It turns a traditional phone into an IP phone device at a very low cost. Not only does it deliver VoIP service at a low per-port cost but the built-in two-port Ethernet switch also allows users to connect their PC to the reserve Ethernet port without adding an extra Ethernet switch or hub. Also it allows users to maintain PSTN phone service and VoIP service at the same time. When ATA power down occurs or VoIP service is not available, outgoing phone calls will be relayed to PSTN automatically. When VoIP service is active, users can place calls to a PSTN phone by dialing pre-fix numbers. Emergency calls or important calls can be relayed to PSTN automatically.
