On Nortel doc, they are saying : "The current anti-virus products Nortel has validated are as follows :
-Symentec AntiVirus 10.2
-eTrust antivirus software 8.0
-TrendMicro 7.3
-McAfee 7.0
"
The document is Nortel Contact Center Planning and Engineering NN44400-210 01.10
Standard Release 7.0,
25 May 2010
I'm using trend micro and it works fine.
Hope this can help.
