Glad I've never had such a problem with Voipo.

I've never heard of anything where the person on the line can 'hold for a few seconds', while the call is redialed. Doesn't really make sense to me.

You never said if your wife was calling your cell phone. I do have bad calls to/from my cell where we choose to hang up and call right back. But nothing like that from my Voipo line to a landline.
