Avaya IP Softphone iClarity error

[SMGJAvaya]

Hello – We are just starting to rollout Avaya Ip Softphones. I’ve installed Avaya Ip Softphone R3, I have also downloaded and installed the SP however; when I try to launch it I get the following error:
"Avaya iClarity IP Audio has detected an internal erro and must close Avaya IP softphone. (For example, this problem may occur if a network interface card is not installed or configured properly in your PC.)"

I have found many threads regarding this problem but no fixes… The SP has been installed and we do not use win firewall… I would appreciate any help! Thanks in advance!

Try changing headsets, some heatsets are not compatible with the sound card driver of iclarity.
