Software+Services: OCS 2007
A company in Finland called Humeko Ltd, is now offering a free one month trial for OCS 2007 services for companies. See full announcement here: http://www.humeko.com/news_20071119.htm (in Finnish only, sorry).
What they'll provide is an interesting package for a fairly cheap price: OCS 2007 (Standard) services including IM, Presence and audio/video conferencing for users, 6,95 eur/month/user. Enterprise gives you Web conferencing on top of that (Live Meeting) for 13,95 eur/month/user.
Great to see OCS gaining more ground!
