Perhaps I missed it, but is there any info / docs on how the DDNS works if you enter a hostname for a network rather than an IP or subnet?
How often is it updated?
Are there any options / configuration for the frequency?
How is it updated? Cron?
Thank you.

Seems to me the DDNS refresh rate is 15 minutes and I think it’s hard-core into the package FreePBX uses. The system will validate the address through DNS WHENEVER there’s activity outside the network, so a good, responsive DNS is a must.
