Ericsson MD110 and Asterisk over H323?

I have Ericsson MD110 PBX with some IPPhones (AASTRA IP Vision) connected over h323 protocol.
I would like to ask you if it is possible to connect my Ericsson PBX wit Asterisk over h323?
I need to connect only one number/account to asterisk (I need to set up VoiceMailBox for this number).
