$ gst-inspect udpsink
...
Element Properties:
...
 host                : The host/IP/Multicast group to send the packets to
                       flags: readable, writable
                       String. Default: "localhost" Current: "localhost"
 port                : The port to send the packets to
                       flags: readable, writable
                       Integer. Range: 0 - 65535 Default: 4951 Current: 4951

I think the udpsink does have this property.
