[Freeswitch-users] Control of IPv6 vs. IPv4

My VoIP provider supports both IPv4 and IPV6 registrations.  I can only have
one registration active at a time.  Freeswitch is attempting both IPv4 and
IPv6 connections.  Randomly, sometimes a IPv4 connection is the first (only)
registration established; other times it is the IPv6 connection.


How to I configure Freeswitch to deterministically only attempt one type (my
choice of either IPv4 or IPv6) of connection?
