Yes, Asterisk can do that fine.
Unless you have an H.323 device with multiple IP addresses, like a CCM
cluster with Skinny phones. In that case, you'll need chan_oh323.

In any case, you'll have to install recent versions of openh323 (and
pwlib) and build the H.323 channel driver (whichever you choose) manually.
It won't work with all devices, though. (I have experienced some trouble
when codecs don't match on H.323 and SIP sides, but that can usually be
fixed by configuring allowed codecs explicitly, if all devices are under
your control.)
