| BeginSendReliableProvisionalResponse(Int32, String, IEnumerable<SignalingHeader>, Boolean, AsyncCallback, Object) |
This method can be used to send a reliable provisional response with option to send answer for early media. If the inviter supports 100rel and the local policy is not unsupported, this method will wait for the PRACK. Otherwise, this method will not require 100rel. Any application that supports 100rel is recommended to use this method for sending provisional response. SendProvisional method can be used only when the application knows for sure that the remote does not require 100rel. |
