I think you're confused. IP Communicator is the unified communications client (IM and Phone) It is looking for a capatible headset so you can use your softphone. This software is not your VPN client. There are two different cisco product: one for your VPN and one for your phone. If you're trying to ocnnect to an old-style Cisco VPN, your IT dept will have to configure that with a certificate.
Solution from Cisco:
This behavior is observed when a user attempts to install or use the IP Communicator on a system that has different names for the Playback (wave out) and Recording (wave in) devices.
In order to overcome this problem, perform one of these tasks:
-Use a USB headset that is recognized by the IP Communicator.
-Upgrade to the latest version of the IP Communicator

My Cisco IP Communicator screen is blank

Is the phones

If it is CME, then it could be a configuration issue

Using Cisco IP Communicator- works to call out & receive calls, but I can hear them-they can't hear me. Also have 3 question marks next to headset icon at the bottom - headset has been tested &...

One way communication is usually a routing issue. Make sure that you have two-way routing to and from the subnets that are trying to contact you... could also be the reason why you have the question mark on the buttons too.

Hope this helps!

Having issues with logging into the cisco softphone from home via vpn

Make sure that the subnet for the call manager is available over your VPN if you have locked the tunnel down. Also make sure that the IPC is allowed to bind to the VPN virtual network card.

Hope that helped!
