Hey DrQwerty90,
You wouldn't read about it but I just got home from work & now the phone service is back up & running so to speak....
To answer your questions there was no dial tone at all & yes I can access the control panel of the Gateway & the Telephony service is Active.
Must have been some delay in activating to voice service. That's all I can put it down to.
However I can't access my messagebank service as my pin is no longer accepted, I'II call Telstra in the morning to see if they can reset the pin.
Thanks for your kind help. I greatly appreciate it.
