Here's the solution - TPG had to input the serial number of my modem (the replacement one they sent me like over a year ago) somewhere on their backend and wait for it to sync up or something.  I do not know why it took so long for them to reach that conclusion - surely this would be listed as one potential solution for them to try when this is the issue.  Why did I have to go through about 4 people on 4 separate occasions to get this resolved?  Thank-you to Lorraine who I spoke with today and managed to fix this with ease.  Honestly, this should have been done from the very beginning instead of stuffing me around and rebooting my modem remotely thinking that would solve the issue.    ...

Yeah, good call @david64 - I saw other posts on here were getting a response from TPG so I figured I'd try this avenue to vent a bit.  Apologies for the lack of thoroughness...after Googling some more I'm convinced it's the modem they gave me which for some reason is not picking up the voip service... I've found multiple other posts suggesting this too.  Anyway, some answers for you/everyone: * Handset is a Uniden 6.0 * I'm on an NBN FTTN 50 with Voice plan * When I try to make a call, I dial a number, it makes the sounds of the digits but then does long beeps and nothing goes through. When I call to the landline it says "Call could not be connected at this time.  Please try again later.  OCA0188" * I have looked through this community page and others outside for answers and nothing definitive to solve my problem other than suggesting it's the hardware that's not configured.  Have done all the troubleshooting like changing handsets, changing cables, resetting modem etc.  Contacted TPG multiple times now and they have not been helpful at all.  Since I can't do troubleshooting via the modem admin portal (since there is no Telephony option and it seems to be a hardware config issue), I am left with contacting TPG who just keep resetting my modem thinking that will solve the issue when it doesn't.   Sigh.   ...
