Hi all, There is an updated version of my MFC/R2 software at ftp://ftp.opencall.org/pub/unicall/unicall-0.0.1b . You will need all the material there. Both libraries, and chan_unicall have all changed. If you have previously patched your channels/Makefile for MFC/R2, the new patch will not apply properly a second time. However, the only change you need to make to a previously patched file is to replace "uni-call.h" with "unicall.h" (I tidied up some messy file naming). This version cleans up a number of details, and handles faults betters. ANI should now work OK. Regards, Steve
