Summary:                    [feature request] Asterisk does not respect DNS TTL
in iax.conf
Description: 
This is probably not specific to IAX but I just tried it for IAX so I am
not sure about the other channels.
The problem is :
when you Dial and IAX channel either by direct dialing
Dial(IAX2/@some_host_name/extension) or by referring to a section in
iax.conf Dial(IAX2/@[section]/extension) and the host names are not IP
addresses but DNS names, Asterisk does not care if the resolved address
changes.
In other words, lets say you have a dynamic DNS that translates to IP_1
and you use this in your configuration in Asterisk. If this IP changes
Asterisk would not respect it and keeps using the old IP until you reload.
It seems that Asterisk resolves the DNS and stores the IP in the memory
(as oppose to having the DNS entry and resolving it each time)
