The Digium™ S101I, affectionately known as the IAXy, takes Asterisk™ from the PC to the CPE.

The IAXy provides a single, fully featured FXS interface with an Ethernet back-end, speaking the Asterisk-native IAX protocol, at a highly competitive price. It 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.
