Required Asterisk,AWS AppSync,OpenSIPS freelancer for help with OpenSIPs, Asterisk and RTPProxy setup job

Hello Toogit,

I am having audio issues with a OpenSIPs+RTPProxy setup on AWS. I am currently able to hear audio on certain types of calls but not others.

I am not exactly sure what the the cause of the RTP problem is. however i DID notice that the RTP packets being sent by our OpenSIPS SBC do not always display the RTP proxy's IP, especially when we use a PSTN network to deliver a call.

I was able to resolve some of the issues by changing the RTPProxy setup to work with AWS NAT. but I have not been able to fully resolve the issues, therefor audio issues are still occurring on most types of calls.

I am looking for a AWS+SIP+VoIP expert to help resolve the audio issues. I will provide full access to the AWS account as well as any info I can to help you resolve these issues.

full list of skills needed:
- AWS experience
- RTP Proxy experience
- experience w/ OpenSIPs
- Asterisk experience

tasks:
- resolve existing RTPProxy issues
- regression test all functionality
- document any changes

please provide an estimate. I am flexible on the budget as this task is high priority and urgent.

thanks
