Xorcom "gateways" certainly do. Again, that's for FXOs 

And generally 

  perl -MDahdi -e '
    my @chans = map {$_->chans()} Dahdi::spans();
    foreach (@chans) {
      next unless $_->type() eq 'FXO'; 
      printf "%3d %s\n",$_->num, $_->battery;
    }'

The "battery" method ATM only implemented on Astribanks in the perl
modules, however this should be soon fixed.
