Hello, I'm a voip specialist with 10+ years of experience working on the TS department of a voip company; I can install, troubleshoot and customize many VOIP devices including: softphones, ATAs, IP-phones and PBX systems like Asterisk/FPBX. I read your project description and checked your attachment, the problem seems to be with your trunk settings; You may contact me through chat at anytime and I'll fix this issue for you.
Thank you.
