Simul Ring Problem

[sal]

I don't have those problems with simul ring. However, I have a different issue.

I normally have voipo phone and cell phone on simul ring when I am away. Wife can call my cell phone from voipo phone without any problem, but, when I call voipo phone from cell phone it only rings once then busy signal.

If I disable simul ring on my cell phone every thing goes back to normal. I learned to deal with this issue by not calling home when on simul ring. It would be nice if this issue is fixed.
