Hello,
Does anybody have Microsoft Office Communicator working through a firewall delivering voice, video and application sharing. I know Communicator is built on the principle of Windows Messenger which works but communicator will only enable me to do a one-way call. I have a DrayTek router and it seems to work correctly. I've been through Google and opened the recommended ports, I've even tried UPnP but get the same issue. I start video connection or voice call, the other end can hear and see me but I get nothing back. Router reports no error, I've even moved the workstation into the routers DMZ and get the same this. Have considered the option that it could be the other end, if they initiate the session it works OK and two-way comms is possible.
Don't have any issues with NetMeeting or MSN Messenger. And workstation firewall doesn't seem to make a difference.
Please let me know if you have it working and what ports are open.
Thanks
Ian
