Maintained version of old asterisk applications ported to 1.4 that for copyright reasons cannot be included into official Digium's releases and that for some reason the author is not keeping up-to-date. The project also require Zaptel instead of DAHDI.

Find out who's calling you before pick up the phone. No extra hardware is required as long as your modem is supported.

This project is for people who want to access one or more HFC-S PCI A based ISDN BRI cards over the DAHDI interface and maybe want to use other DAHDI hardware in parallel, too. DAHDI driven hardware can be used by Asterisk, FreeSWITCH, Yate and other telephony software. The HFC-S PCI A based cards are very cheap and thus ideal for private BRI users. The OSLEC is being developed since a long time ago and said to be very good. The superiority of "hardware echo cancellers" is a myth. This makes the fact that HFC-S does not have a hardware echo canceller an advantage if you decide to better use free software and maybe even improve the echo canceller. The dahdi-hfcs is the latest Digium DAHDI kernel module svn trunk plus adopted and properly renamed zaphfc driver plus latest OSLEC echo canceller svn trunk, all ready to compile out-of-the-box. By default only the things you need to drive a HFC-S PCI A based ISDN BRI card plus some software drivers like dummy device and echo canceller
