Summary
The economical Zoom Model 5801 Voice over IP Telephone Adaptors allow standard analog telephones to make and receive calls over a broadband Internet connection. Simply plug a conventional or cordless phone into the Adaptor and then plug the telephone Adaptor into a broadband-connected router or Internet gateway. Up to five and often more attached phones can be rung simultaneously using the built-in ring generator. The Model 5801 support industry-standard Session Initiation Protocol (SIPv2) and work with a wide range of service providers and SIP-based VoIP equipment. Both models provide one FXS and one FXO port and allow calls to be bridged between the Public Switched Telephone Network (PSTN) and Voice Over IP. The FXO port of the Adaptors also include the TelePort, an intelligent relay that allows a single phone to place and receive both VoIP calls and calls over the PSTN. PSTN fail-over allows the 5801 to automatically route calls over the dial-up phone network when power is lost. PSTN support also allows emergency dialing using services like 911, 112, or 999 calling. PSTN to VoIP call bridging with security is provided, as well as VoIP to PSTN call bridging. Voice over IP Service providers can deliver a rich variety of advanced telephone services through the Model 5801 including CLASS features such as Call Waiting, Caller Identification, Call Transfer, Call Hold, Call Forwarding, Distinctive Ringing, and Voice Message Waiting Indication.

Description
The VoIP telephone Adaptors can be configured remotely using a TFTP or HTTP download from the service provider and updates to the firmware can be automatically delivered. Local configuration is done with a browser-based graphical user interface. The Model 5801 supports G.711, iLBC and G.729 voice codecs.
