I have gone through your project requirements. From that what I get is you want Cloud-based VoIP service with external calling like PSTN or any cell number. Don't mind but I'm wondered why you are using two seperate servers as this can be done with only one server. AWS charges more if you have more running servers. I have implemented same scenario in a company, where I have used FreePBX which is also an open-source VoIP telephony OS and instead of [login to view URL], I have used Twilio. You can use [login to view URL] though. In my project, I have used one FreePBX server, Twilio as a SIP provider, created SIP Trunk with Panasonic PBX so that our VoIP can work with analog phone system as well. Also, Cisco's IP phones, Sangoma's IP phones and few VoIP applications in Apple and android. I also wrote that solution in my blog ravikumarsadhu.com. You can refer that. If you like that then just drop a message, I will start working on it. If you have any questions, feel free to ask me. I can charge you less but Freelancer app doesn't let me do that as it has minimum amount restrictions. Thank you so much for your consideration. I am looking forward to hearing from you.

Hello, I have 10 years of experience working as a level-2 and NOC technician for a VoIP company based in the US, I'm familiar with many systems and several voip-phones, ATA, softphones and PBX, I used to be the primary contact for PBX and priority partner cases, more specifically Asterisk or FPBX, I also worked close with the engineers (sysadmin); I read all your request and I understand you will be running Kamailio(SBC) to terminate the calls to Bandwidth, and Asterisk(PBX) will be handling media and registrations, I couldn't understand exactly what you want to accomplish with your request 2) I assume you want a connection between the PBX and SBC to proxy the calls through the SBC/Bandwidth, and 5) it's not clear to me if "PSTN" calling you mean to setup a PSTN gateway like an SPA3102 or a TDM card for Asterisk. Please contact me for a bit more clarification on these tasks and I'll be happy to work with you to get everything setup. Thank you!
