AG-188N is a small adapter designed for Internet based telephony. It adapts the SIP and IAX2 protocols as well as multiple voice compression codecs to directly convert analogue voice into IP packets for Internet transport, thus effectively using the existing bandwidth to provide PSTN quality voice service.

AG-188N series one port voice gateway supports both the SIP and IAX2 protocols, offering one 10/100Mbps Ethernet interface, one FXS port and one FXO lifeline port. AG-188N is small and can be widely used in SOHO, small office and enterprise branches.
