Simulring, vm

I am using simulring to ring my cell phone and home phone when a call comes in. I would like to disable the Voipo VM and have the calls just go to my cell VM if I don't answer either line. I am having trouble getting that to work.

I tried setting both for 20-30 seconds, auto answer and disabling the Voipo VM, but that didn't work.

Any ideas?

I believe the VOIPo setting is based on the number of rings, not seconds. In any event, try setting the VOIPo VM for a significantly longer time than the cell phone VM, e.g., 8 rings.
