*28 + Simul ring = home phone not ringing and falls back on the simul ring list

[rx100]

I enabled the *28 and Simul ring, now my home phone won't ring, it falls back on the Simul phone. Also I don't hear the ring tone at all even though the simul phone rings.

e.g:
1. Phone # 123 456-7890 is added to the *28 incoming list
2. Simul Ring enabled
3. When I receive a call from 123 456-7890, the home phone won't ring, but the other numbers from the simul ring rings
