check out a news release from VoIP Inc / Voiceone tomorrow and then thursdays release... All of what your asking for is being released in two parts, first the IM platform tomorrow, then the first set of of "universal" calling services on Thursday. You will be able to see the news releases for all of this at: http://wwww.voiceone.com/ and http://www.click4me.net/ also traded as VOII, so will popup on newswire as well. Sorry I cant say too much more (part of the company), but everything, from any platpform PC, MAC, LINUX, AND CELL PHONES, as enabling seemless chat, and ALL being able to make voice inbound and outbound call - including to/from the PSTN.... Also adding functionality for current click-2-call stuff where currently it calls a phone number, to allow it try your IM account first to see if you want to take the call on your IM client, or forward to your contact phone number... some cool stuff coming down the pike....
