We recently implemented Call Manager 6 with CUPC. We are seeing issues with users working off of our network and are unable to get presence status when logging in. We have seen a few issues that could cause this. These include the following:
Windows Firewall is not allowing exceptions
VPN Adapter Statful Firewall is on
We are using CUPC 7.0.2 and VPN Client 5.0.02.
This issue is not across the board. I would say appx 100 users report this issue. We are using Windows XP Pro on our image. Any suggestions?
