So I've about had it with the paperweight TG799 that Telstra have supplied and I want to upgrade to something that isn't a piece of junk.
I have tried putting it behind another router but have intermittent issues with incoming calls going straight to voicemail regardless of what I do with ports and DMZ etc.
Why do Telstra refuse to give me the SIP settings to configure my own ATA? I asked them and got some bollocks about "Security reasons", which sounds like crap to me considering every other VOIP provider gives you these settings.
Of course they refused to connect me to the Uni-V port too
