[Freeswitch-users] SIP and nat traversal IPv4/IPv6 issue

[Anthony Minessale]

can you confirm that they are not being inherited by some of the helper
variables exported from vars.xml?
can you minimalise your ip4 profile by cutting all the commented lines and
actually remove the ext-rtp-ip and ext-sip-ip params?
Then possibly post your config for each profile.
