Remarks
This method allows applications to handle the session negotiations for a session. The application may choose to handle session negotiations for several reasons; for example, when the application wants to include media stacks that are not supported by the RTC Client API. For more information, see Session Negotiation.
This method can be called on any incoming session, including a session re-Invite request.
Note The content type is application specific. Applications should ensure that the called party is able to decipher the content type of the session description. The request for an incoming session may fail if the application cannot decipher the content of the session description.
