I just recently returned to using BOINC with the WCG projects. I have a slow DSL connection and use VOIP (without any good QOS on router) and I noticed right away that my call quality was suffering, but this was while BOINC was suspended (computation is suspended, network activity is suspended). I even manually suspended network activity from the menu. Yet, using ProcessExplorer I can see that boinc.exe and boincmgr.exe are sending and receiving data, and there are no transfers showing on the Transfers tab. Can anyone explain why BOINC is still using my network and how to truly restrict this? Thanks.

PS I am using version 6.10.58 on Windows XP. The current tasks are HFCC and FAAH.

BOINC isn't using your network. What you see is local traffic, called an RPC, through port 31416, the TCP port that BOINC uses to talk among its parts.

For instance, the showing of the Tasks tab and all values inside it, needs to still be updated every now and then. That's the 'traffic' you see.
