I am have an issue with a softphone setup. I am trying to use my existing extension which is connected to an Avaya 5410 phone. I am running 4.0.7 and IP softphone version 5.2 SP4. I keep getting the error You are attempting to log into an extension that is associated with another station. Would you like to override that association? When I select Yes the prompt will not go away and it will not connect. Any help much appreciated. THanks!
