[Freeswitch-users] error creating IPv6 profile when corresponding IPv4 port in use

[Jason White]

The solution was to edit /etc/asterisk/sip.conf and change
bindaddr = 0.0.0.0
to
bindaddr = x.x.x.x
where x.x.x.x is, naturally, replaced by the host's actual IPv4 address.

Following this change to the Asterisk configuration, Asterisk can bind to port
5060 under IPv4, and FreeSWITCH can bind to port 5060 under IPv6.
