hi..

no its nothing to do with the new Mosaic Service. check the antivirus installed on ur pc. that might be blocking the VOIP. its a new pc as u have written. if its branded norton 2007 is installed then. try to change the settings under the firewall option. i use skype and i live in the old airport till now no probs.

if any other problems, please feel free to write..
