Voip software creation with automation (Repost)

Our developer has been at hospital for 3 months, so we need a replacement to start our project. We need to create a new voip software from scratch similar to goip/antrax, the detailed file will be submitted for all the requested features.

The project will be divided into a 3 to 5 milestones.

Pls bid only if you have experience with voip before and you've seen antrax/goip/dinstar softwares before

Coding language should be Java or C or C++, the essential is to be a very fast software without bugs and without errors or crashes. So you can choose the faster language

The main features will be:

1 - Very high quality voice

2 - Cloud remote control

3 - Can accept bulk calls over 10K calls per second without any crash

4 - Automation (will be described in details)

5 - Software can work even with low internet speed or 4G with high quality voice

Moreover we would like to have after sale support for 3-6 months making sure that there are no bugs in the software after testing it with some of our clients. And after that, after sale support will be paid.

Pls bid the best price possible in order to establish a long term business relationship.
