Our street in Napier has just been rebuilt for UFB and NowNZ, aka AirNet, have offered a voice plus data package. I phoned them regarding the voice quality and they said it would be good. I asked what codec they would use and he said G.729, although he wasn't sure. However, he was sure that the POTS line would be connected to their equipment, not the Chorus ONT.
My question is why would a Residential Service Provider choose to use their own Analogue Telephone Adapter when the Chorus ONT has one, and with a G.711 codec? I cannot imagine why I would change to fibre and then have to talk to people with a tin can and string.
