UniqueID is composed of the epoch when a call starts, plus a monotonically
incrementing integer.  Together, they will be unique for all calls originating
from a single machine, as long as they are treated as a string and not as a
float.  Note that you can set asterisk to prefix the hostname to a uniqueid
from asterisk.conf, which should make uniqueIDs globally unique (as long as
you aren't repeating hostnames).
