TPG and ABB (Aussie Broadband) need no introduction, but the shite way one of them does business and treats its customers is the chalk to the others cheese.
Long time socials followers, would be well aware of the frustrations and problems I've had to tolerate with TPG. I took up their service in 2010 as a static-IP account, yet after about 6 years, TPG forgot the meaning of static-IP and changed our IP - without notice - not once, but three times. This is a problem when your IP Address is in many firewall ACL's to perform remote management.
Configuring FreePBX to use a VoIP provider is usually simple and quick, but sometimes there's always one of the bunch that wants to be different in how they expect you to configure your Trunk, and Aussie Broadband (affectionately known as Aussie, or ABB) is one of them.
With ABB doing things differently, you'll find the usual way of setting up a SIP trunk in FreePBX wont work, and you'll probably go half insane trying to work out why.
