hi, i read the onsip.org <http://onsip.org> getting started manual. i tried again with ser and rtpproxy but i received same errors... then i decided to try with mediaproxy: i downloaded ser-0.9.0 (emerged from gentoo portage) and mediaproxy-1.4.2. i followed this instructions: http://www.voip-info.org/wiki-MediaProxy but i cannot even start it (neither --help works) $ /etc/init.d/mediaproxy start : bad interpreter: No such file or directory and: $ /usr/local/mediaproxy/mediaproxy.py : No such file or directory i got ensured that EOL are not dos-style and i tried that a simple file called test.py (it just prints something) just to make sure that python works... sorry, i understand it is not properly a ser problem but i don't know where else to ask... thank you so much!
