Hello, I'm a voip specialist with over 10 years of experience working on the TS department of a US 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 I can help you build your toll-free solution for resale, I'm wondering though, do you need US toll-free numbers or toll-free from other countries ? Feel free to contact me through chat at any time.
Thank you.
