Public Function BeginSetConnection ( _
		proxyHost As String, _

		transport As SipTransportType, _
		userCallback As AsyncCallback, _
		state As Object _
) As IAsyncResult

public IAsyncResult BeginSetConnection (
		string proxyHost,
		int proxyPort,
		SipTransportType transport,
		AsyncCallback userCallback,
		Object state
)

Parameters

proxyHost

The proxy host for the connection.

proxyPort

The port for the proxy.

transport

The transport.

userCallback

The callback to be invoked when the SetConnection operation is complete.

state

The state to be passed back to the callback.

Return Value

The initial INVITE for the session uses this connection instead getting the connection based on endpoint settings. This method can be used only for SipPeerToPeer endpoint. Signaling sessions for SipEndpoint use the connection maintained by SipEndpoint. The transport specified for the connection should be as secure as the transport needed to send the INVITE or else the Participate method call might 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.
