I'm looking to implement an internal IM solution within my organization, and I'm curious of your thoughts on which solution is best, and if you're using anything now (or have implemented anything in the past) and how that's working out.
I'm looking to have some level of administrative control, especially filtering or something. Integration into AD would be nice too, all while trying to keep the cost low. Also, I want this to be strictly employee only.
Here's what I've come up with thus far, with the Openfire being my most likely choice at this point.
* Openfire http://www.igniterealtime.org/projects/openfire/index.jsp
*AIM Pro http://aimpro.premiumservices.aol.com/
*MS Communicator http://office.microsoft.com/en-us/communicator/FX101729051033.aspx
I have seen several other solutions (Global Relay, Big Ant, 24im) but they are too costly.
Thanks to everyone for your help! (Points will be distributed according to how useful your suggestion is.)
