I did this video to show the phone working on the HFC NBN with Telstra. I haven't had any problems. The phone is a lot clearer on the NBN using VoIP. I still use a landline phone these days. This is the Australian dial and busy tones here in 🇦🇺. The telephone rings the same as a U.K. And 🇳🇿. We have an 8 digit phone number and a 2 digit area code here in Australia. #hfcnbn #nbn #telstra #landlinephone #cordlessphone #speakerphone (at Brisbane, Queensland, Australia) https://www.instagram.com/p/BXkTLu4gAWb/?utm_source=ig_tumblr_share&igshid=be7dtmkjg39r
