unfortunately this doesn't work on jessie because dpkg-buildpackage doesn't have --no-sign support: ``` make deb make -C src/ deb make[1]: Entering directory 'kamailio/src' (cd ..; \ if [ -d debian ]; then \ dpkg-buildpackage -rfakeroot -tc --no-sign; \ rm debian; \ else \ ln -s pkg/kamailio/deb/debian debian; \ dpkg-buildpackage -rfakeroot -tc --no-sign; \ rm debian; \ fi) dpkg-buildpackage: unknown option or argument --no-sign ```

IMHO you should use -us or --unsigned-source
