Information in this document applies to any platform.
With Chrome 58 there is a huge delay (around 40 secs) during the session establishment (ice gathering). This is something associated with the browser and we doesn't seem to have any control on the SDK.
For web-to-web calls this can be solved by using trickle-ice. Nevertheless, for web-to-sip or sip-to-web the GA code is not prepared for this.
When trickle-ice is enabled, the SDK will send "trickle" messages. By default, the WSC maps these messages into SIP INFOs. Unfortunately, if there is a web-to-sip or sip-to-web scenario, the remote SIP endpoint won't understand these SIP INFOS and will discard them (or worse, disconnects the call).
