Hello briefcase, I'm a VoIP specialist with 10 years of experience working in the TS/NOC departments of a US VoIP company; I can install, troubleshoot and customize many VoIP devices including softphones, ATAs, IP-phones and PBX systems like Asterisk/FreePBX. I read your project description, and I can certainly setup your Twilio trunk with your Asterisk system. I'm available through chat to discuss this project further, and get started. Thank you.
