Do NOT apply if you are going to charge more than $50. I have ViciDial PBX setup on a local server, but I have lots of issues with my ISP. I have rented a dedicated server with CentOS 6. I need someone to code the server to run Asterisk and ViciDial. Also, I need you to move my DB from my old server to the new one you will setup, so I have the same campaigns, lists, users, etc...

Hello! I need a developer that has solid experience working with Linphone and/or other VoiP apps to customize the UI and add new features like allow calls to regular phones, add end-to-end encrypted chat, allow users to buy a virtual phone number, allow call to regular phones, etc. I need the freelancer to do the full service, from developing to submit the app in app store (I already have an account and everything setup). I also need a RELIABLE and TESTED product because I'm very time sensitive and that's why I'm hiring an extra freelancer instead of developing with my own team. Availability for communication is also very important. I've had many bad experiences with freelancers that disappeared suddenly and I don't want to repeat this. Please feel free to ask in case of any questions :) Thanks!
