I suppose I should join as well.

Up until a few days ago, the Simul Ring always worked fine and I could answer from my cell when I was out and about.
The last 2 calls, and I didn''t get many over the weekend as we were away for 2 days, had the same experience as fisamo...I answered and the cell disconnected. My answer machine did pick up the calls at the house.
My machine doesn't answer until after 4 rings and I answered my cell long before that.

The last call that I answered on my cell when it disconnected was at 10am today. It did leave a CID on the cell. However...at 1:02pm yesterday, I was able to successfully answer a Simul Ring call from my cell.

Since it has worked well for me for quite a while, I suspect some sort of glitch or maybe they did some programming change..
