Countries such as Egypt typically block VOIP applications that don't have a license to operate, that might be the reason why the non encrypted protocols aren't working. Check with your ISP if they're blocking the connection. I know that Linphone also offers a tunnel for their VOIP application, that might be a solution for you.
