IAX2 and DNS issues with FreePBX13

@sorvani wrote:

Steps to replicate
Create IAX2 trunks between servers and use DNS names instead of IP addresses

For purpose of testing this, I have a simplified IAX2 config.

type=friend
qualify=yes
host=pbx.site1.com
deny=all
context=from-internal
allow=ulaw

Right after you apply config you will see this. Repeatedly.

Showing the peers results in no IP listed.

Eventually, DNS will refresh.

But the trunks do not come online.
