BLF not working

[awakener]

I think this BLF is not working at all with Polycom phones. I have worked with Cisco Callmanager and Broadsoft and always the BLF worked flawessly. The problem is now when I connect the phone to 3cx then all the extensions appears on the phone display. I haven't selected any BLF's on the 'Phone Provisioning' tab. So how is it possible that I get all the extensions on my phone? I hope someone can help because I am a tester of this product and if this isn't going to work then Broadsoft is the only option...

Thanks in advance...
