<dd>
</dd><dd> Choose whether or not you want to use ICE (Interactive
Connectivity Establishment). ICE optimizes the media path. This would be
the case, for example, when two phones in the same network are calling
each other via a long media path through other, external networks. With
ICE, the short media path in the same network would be chosen, which
will presumably have better quality than the long one. Sometimes this
feature will stop you from being able to make calls. When this occurs,
switch it off.
