Development of the EWindow Software is focused on several parts:

1) SIP portocol We use the standard protocol for IP (video) telephony, SIP optimised for light supports, as Raspberry Pi. Our implementation is based on the minimalistic SIP client Cash dip. This has proven to be suitable, with low hardware resources to enable an acceptable connection quality, because it has a modular design and is designed to support special video hardware resources.

4) A set of build recipes for Alpine Linux The complete system is based on the Linux distribution Alpine Linux, from that automatically creates pre-configured live images.

5) ECho Cancelation The echo suppression for undisturbed hands-free communication is based on currently on pulse audio or code from the Google WebRTC project.
