      <pre>It works nicely for home use for power users who can accept the odd lost
call and know how to restart the app or the phone when something goes
wrong. Unfortunately I haven&#39;t found anything so far which works for
business use.

The largest problem is that smartphones can&#39;t afford (battery-wise) to
check for wifi connectivity all the time. If the phone loses connection
to the wifi, it often takes more than a minute before it is ready to
receive calls again.

        <pre>What models/brands are optimal for this (in terms of ease of use,
battery life etc)?

      <pre>iPhone, Android, and Symbian are about equally troublesome.
