Calls garbled at other end all of a sudden

From around 2 weeks ago both my wife and I are experiencing frequent call quality issues. It might happen right from the start of a call or part way through but the voice at the other end becomes garbled and impossible to understand and the person at the other end can hear us just fine. We are both on iPhones with the latest firmware. Switching to calling via Facetime or Whatsapp present no such issues. I have also experimented with wifi calling on and off and that doesn't seems to change anything. Interestingly this only seems to occur when we are calling from home (Eltham, VIC). In other areas the problem doesn't seem to exist and only starting happening at home 2-3 weeks back.
