I've used zaphfc (it was obviously included in original Debian-s Asterisk package), but after 0.40 it seems that vital module for me "zaphfc" is missing. Since zaphfc is a driver for majority of cheap HFC-based ISDN cards, it's important (I have still normal ISDN line that goes into Pluto core) - at least for me...
Patch for Asterisk can be found here :http://www.junghanns.net/en/download.html
Maybe there is some other way for using those cards (don't know much about hisax, etc..)
Any opinion ?
