USB Headset locks up i2050

[lewmar]

Hi,
We have call center on BCM450 R6.0 with latest patches installed. Agents use NTEX14AC USB Headsets on i2050 softphones Rls 4.04.0067. Couple times a day softphones are locking up and need to be restarted.
Had anybody experienced similar problem?
Thank you.

Have you tried downgrading the softphone version... just to check- If this should work then a case with Avaya will need to be opened
Also make sure there the firewall is allowing port 7000.
