the most important thing is that asterisk doesn't support
remote-party-id that is a must for call forwarding and calling number
privacy.  

a good pstn gw also allows controlling what to do with 3xx replies and
refers.  it is also desirable to be able to select which interface is
used for signaling and which for media.  some of these may be possible
in asterisk, but i'm not sure.

one advantage of asterisk over cisco is that * has support for free low
bit rate codecs ilbc and speex.

jan already answered that sems currently supports.  nothing would
prevent adding into sems also support for digium te405p/te410p, which
i consider a good thing to do.
