SInce FreePBX does not honour the proxy settings via the bash export, you need to tell Apache instead to use a proxy. This would apply for FreePBX as well. Here’s a how to for Debians. 1) #nano  /etc/apache2/envvars 2) Add the following codes at the end. You will notice that there’s repeats, sometimes they are needed so keep them there twice. export ftp_proxy=http://10.50.19.206:8080
export http_proxy=http://10.50.19.206:8080
export FTP_PROXY=http://10.50.19.206:8080
export HTTP_PROXY=http://10.50.19.206:8080 3) #/etc/init.d/apache2 restart Where 10.50.19.206 is the proxy server and 8080 is the proxy port, you can also insert an auth username like this for all instances above. http://username:[email protected]:8080
