The Digium™ S101I, affectionately known as the IAXy, provides a single, fully featured FXS interface with a single Ethernet connection, speaking the Asterisk-native IAX protocol, at a highly competitive price. This product replaces the older S100I.

The IAXy is aimed at Voice Over Broadband and Internet Telephone Service Providers. The IAX protocol provides complete NAT transparency, enabling full operation behind NAT and PAT firewalls. This includes the ability to robustly transfer calls between endpoints, allowing on-net calls to be moved off of a service provider's network for better quality and lower cost.
