I just ported our landline to voipo and was trying out features.

I was away when the port was finalized and had set up simultaneous ring to my cellphone. When I got back I was dismayed to discover that when I called my landline from my cell, the phone would ring, and then would beep and drop the call. Wasn't sure what was going on but this stopped when I disabled simultaneous ring.

I didn't have this problem with the simultaneous ring feature of a different voip provider on a different number.

Let me know if you need additional information to reproduce this problem
