Hello,
I have gone through your project details. I understand that you need to configure your Openwrt Router to pass 32 calls using g729 codec using any one the technologies mentioned in your project description. I am a server and network administrator with 4+ years of experience in VoIP Service management. I have worked on many VoIP based projects, none similar to this one. However, I am quite confident that I can manage this particular project. I am sure, you will find all skills in me that you have been looking for.
Please let me know if we can discuss further regarding this project.
Regards
