I know this has been a topic before in 2014. I had a 5330 phone that was damaged in a lightning strike. I'm a remote employee, so I believe my phone is set up differently than employees in the office. I received a new 5330e phone, & I am using the same Bluetooth headset I was using before. I am now getting the hookflash disallowed message when I answer incoming calls. Since the answer to this question in 2014 was a software upgrade, does this mean my company has not upgraded software for at least 4 years? Also, does the "e" have anything to do with this? They are saying it does but what I've read seems like there should be no issue. Thanks.
