Parallels 4 with Windows XP SP2 I installed Cisco IP communicator on the XP image and it runs fine and has picked up my number, when I press new call, I can hear the dial tone, but once making a call, there is no sound, no ringtone and if the other person picks up the phone, they can hear me, but I cannot hear anything. I ran the audio wizard and the sound comes fine when I run this, it just when I make a call. I have also turned the Windows firewall off, but that made no difference. Any idea? Is there some setting in Parallels that needs to be enabled?
