    media-pipeline: Bind to the unspecified IPv6 address
    
    IPv4 keeps working through the magic of IPv4 mapped IPv6 addresses.
    
    Without this change errors about invalid address family will be raised
    when trying to connect to a IPv6 host.
    
    Bail out! CallsSipMediaPipeline-FATAL-WARNING: Error on the message bus: Could not get/set settings 
from/on resource. (../gst/udp/gstmultiudpsink.c(1228): gst_multiudpsink_configure_client (): 
/GstPipeline:media-pipeline/GstUDPSink:rtcp-udp-sink:
    Invalid address family (got 10))
