[Freeswitch-users] IPV6 addr change killed sofia profile internal

Mon Jun 2 21:06:27 MSD 2014

auto-restart is also a per-profile setting the one noted just sets it on
all of them.
It will restart profiles who have the ip that changed present in the rtp-ip
or sip-ip.

I did just see an errant restart_all_profiles call in the code in questions
which will be corrected.

We can see if we can improve its resilience.
