Sets the connection to use for the outgoing signaling session before calling Participate. The initial Invite for the session will use this connection instead getting the connection based on endpoint settings. This method can be used only for SipPeerToPeer endpoint. Signaling sessions for SipEndpoint will use the connection maintained by SipEndpoint. The transport specified for the connection should be as secure as the tranport needed to send the Invite or else the Participate method call may fail. IMPORTANT: This is an advanced API. To work properly, the application should call this method before every redirect as well. The RedirectReceived event call back handler in the application should use TryThis and call this method before returning.
