Hi there! I'm Saira Arif, a Linux Engineer and Full Stack Developer who has extensive experience in PHP, Linux, Ubuntu, Centos, Kali Linux and Debian. I understand from your project description that you need help setting up freepbx followme correctly so that it can handle calls that exceed the ringtime. This is something that I have experience with - specifically on a server with an FXO card - so I believe I am the perfect person for this job.
I have worked with Asterisk before and I know how to set it up correctly for maximum performance. This is something that is important to you because you want your call to be answered within 9-10 seconds of reaching the destination. Otherwise it will go to voicemail or an IVR.
