How can I check the version before installing a package using 'apt-get'?

I'm thinking to install hylafax+ version 5.5.4 which was released last month on my Debian PC.

I checked dpkg -l | grep "hylafax" and found out that the current version is 5.5.3. Then I checked apt-cache search hylafax and saw the packages are available, but I can't see any version number.
