For VCS

1. Add <category name="ipv6"/>
2. Change <item name="IP">::</item> for <category name="MRCPSRV">


For SIPMethod

1. Change kernel.ms.rmi.address=:: in sipenv.properties
2. Change <NetworkAccessPoint transport="tcp/udp" address="::" port="5060"/>
3. Change MEDIA_SERVER_URI="mrcp://[::1]:9974"

Since VCS have a bug when parse IPv6 HTTP URI, so we haven't to change HTTP NAP and URL to IPv6, both in sipmethod.xml and config.xml
