SNOM-105, SNOM-200, and all Cisco phones should support PoE.

easiest solution: wait ~1 year until Cisco come's out with a SIP based
CallManager on Linux.

quick solution:
Use Asterisk with chan_oh323 as an H.323 to SIP converter, configure it
as an H.323 Gateway in CCM and register your SIP phones to *.
Make sure to restrict codec selection on the Asterisk side: Translations,
even from A-Law to Mu-Law, are likely to produce segfaults with this
setup. Apart from that, it should work fine.
