Major Improvements and Bugfixes

We have implemented new diagnostic and logging architecture for Web Call Server

We released way to speed up WebRTC connection establishment removing stun_server settings. When we remove stun releated settings, WebRTC implementation does not search external candidates and uses local interfaces as candidates in the created SDP in offer.

Delayed offer is supported since WCS3 client-server build 425-527. The delayed offer means we receive INVITE without SDP.

Currently WebRTC does not work properly with re-INVITES, re-offers.

Added two server-side settings: “flash_codecs” and “disable_rtc_ata”.
