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

[Mario G]

An update: I did not find a JIRA or I would have posted there. Anthony’s patch has been in for 2 weeks and no problem with auto changing IP6 addresses so far. Still, we need some time of auto-retry for profile internal failures to solve other issues.
