Syntax
public sealed class LegacyCall : VoiceCall, IAsyncDisposable
Remarks

Events of the call reach HandleAsync(string, string, CallContent), which runs them one at a time with this side's actions. Candidates are sent in batches, as Element does, and end with an empty one; those received before the offer or answer wait for it.
