No, it will not re-lookup! When dnsmgr is off asterisk does name resolution once and forever.
Interesting. That makes zero sense. The whole point of having a TTL is to have lookups refreshed when they expire... oh well, good to know.
What, in your opinion, would then be the point of the supposed dnsmgr
It actually makes perfect sense when you think about it from the programming perspective: name resolution is only done when you load the config, so TTL plays no role whatsoever.
Basically, such a setup is only one step further from hardcoding IP-addresses by hand. A lot of system tools are designed like this (for one, firewalls come to mind, and ping, and ssh, and basically every other simple tool).
