I've spent some time to get Zaptel running with 'Bristuff' Asterisk provided by Junghanns (http://www.junghanns.net/downloads/bristuff-0.4.0-RC3e.tar.gz). Here is a path to compile zaptel.

During asterisk installation (install.sh) you can face such an error:

zaptel-1.4.12.1/kernel/ztdummy.c: In function 'ztdummy_hr_int': /usr/src/bristuff-0.4.0-RC3e/zaptel-1.4.12.1/kernel/ztdummy.c:202: error: 'struct hrtimer' has no member named 'expires' make[3]: *** [/usr/src/bristuff-0.4.0-RC3e/zaptel-1.4.12.1/kernel/ztdummy.o] Error 1 make[2]: *** [_module_/usr/src/bristuff-0.4.0-RC3e/zaptel-1.4.12.1/kernel] Error 2 make[2]: Leaving directory `/usr/src/linux-2.6.29.5' make[1]: *** [modules] Error 2 make[1]: Leaving directory `/usr/src/bristuff-0.4.0-RC3e/zaptel-1.4.12.1' make: *** [all] Error 2

Proceed with this instruction:

1. cd  /usr/src/bristuff-0.4.0-RC3e/zaptel-1.4.12.1/kernel/

2. Created the file ztdummy.patch with:

3. Patch it:

patch -p0 ztdummy.c ztdummy.patch

4. In /usr/src/bristuff-0.4.0-RC3e/ execute ./compile.sh (NOTE: ./install.sh will remove this patch). Now the error looks different:
