This is possible as long as you reinvite the media between the devices
directly; if Asterisk is handling the media and the box goes down,
then the media will be taken with it. If you are using Asterisk 1.6.x,
then you can also use SIP session timers to make sure the devices
don't go away without telling you they are going away (for example a
power outage at a the remote location, or someone rebooting their
phone).
