Odd Google Voice Behavior

[ceg3]

I have been using a stand alone answering machine to field calls to my GV number.  I decided to start using GV voicemail again and tested it by calling it from my mobile.  On three successive calls voicemail picked up, but my phones in the house continued to ring.

First obvious step was to delete my GV account and add it back.  After doing that incoming calls from my mobile worked properly.  Hopefully, the fix will stick.
