DNS Resolution fails in latest version

[InnovativeUS]

When resolving an address it is not set in the message

func TestTransportLayerClientRequestConnectionResolution(t *testing.T) {
for _, tran := range []string{"UDP"} {
t.Run(tran, func(t *testing.T) {
tp := NewTransportLayer(net.DefaultResolver, NewParser(), nil)
req := NewRequest(OPTIONS, Uri{Host: "localhost"})
req.AppendHeader(&ViaHeader{Host: "127.0.0.1", Port: 0, Params: NewParams()})

		_, err := tp.ClientRequestConnection(context.TODO(), req)
		require.NoError(t, err)

		tp.Close()
		require.Equal(t, "127.0.0.1:5060", req.Destination()) <-- This is set to localhost:5060 in the latest version
	})
}

}

Uncommenting the line 406 in sip/transport_layer.go fixes the issue but not sure that is the correct solution.

if raddr.IP == nil {
	if err := l.resolveAddr(ctx, network, host, req.Recipient.Scheme, &raddr); err != nil {
		return nil, err
	}

	// Save destination in request to avoid repeated resolving
	// This also solves problem where subsequent request like NON 2xx ACK can
	// send on same destination without resolving again.
	// req.SetDestination(raddr.String()) <-- Uncomment this line fixes the issue
