For some reason the ./configure script in the astunicall-1.4.9-0.1.tar.gz does not work and do not generate the Makefile. I think it has something to do with the fact that chan_unicall.c and channels/Makefile are included in the package. So, a workaround for now is to just download asterisk 1.4.9 from asterisk.org and then copy channels/Makefile and channels/chan_unicall.c from the astunicall package.
