I have an issue with the configuration of 2 phone (7961 Model). They are configured as Mirror images of each other. The first phone is configured with the folloeing Lines: 3240, *3240, **3240, 3300, *3300, **3300. The other is just the opposite: 3300, *3300, **3300, 3240, *3240, **3240. The issue occurs when the User on the first phone receives a call on her primary lin. and picks up. If she receives a second call that goes to her rollover line and it is picked up on the other phone, that individual is unable to transfer that call until the user on the first phone hangs up her line. The problem occurs in the other direction also. Thanks!
