I will escalate your issue to our VOIP engineers. They will get back to you as soon as possible.
Thanks Nirmitha,

but no need. Everything is working good so far. I posted this update as a few people had put some time into it, and then I left it dangling as I had to attend things elsewhere for a while. And so I wanted to update the final outcome.

Hi Dazzled,

I did a long reply with all my theories but got distracted, wandered off for lunch and lost everything. The system probably timed my session out or the like.

Anyhow, forget my theories, here are the firewall rules, between the asterisks is what I added. The other references to the ATA ip and port 5060 are not my doing.
