The iSociety, that MySpace-like Web site for System i devotees, will be holding another of its “fireside” chats tomorrow, this time on the topic of Voice over IP, or VoIP.

IBM, as you know, has been trying to sell the System i as a perfect integrated platform for all your VoIP needs. Last year, IBM and 3Com announced their joint offering — IBM’s System i hardware combined with 3Com’s VoIP hardware and software. Then in June, Nortel got into the System i VoIP mix, joining with IBM to offer competition to 3Com.

It’s still unclear if SMBs will take to VoIP, as the pain of setting it up can outweigh benefits for small businesses. One major pain point: having to deal with too many technologies and too many vendors to get a VoIP system going. Does IBM’s integrated offering on the System i mitigate that, and if it does, will it bring new System i customers into the fold? That remains to be seen.

Anyway, the fireside chat is at 1 p.m. EDT tomorrow at the iSociety’s fireside chat site. It will include Mike Rousseaux, an IBM offering manager for collaborative technologies; and Roxanne Reynolds-Lair, the CIO of the Fashion Institute of Design and Merchandising, an early IBM VoIP adopter.
