I purchased one recently as well, and like the phone, though not so sure speaker / call quality on a par with either beocom 2 or 6000. In fact briefly considered returning and reverting to a 6000. I am wondering whether this may be a result of the duplex function.

Anyway, also have two phones to the same line - also have a corded phone - and have the same ring delay on answering; often the caller will ask whether I need to answer the other phone! Prior to the beocom 5 I had the 6000 connected, and same delay. I guess this is the BT line connection as opposed to a phone issue.

We have two beocom 6000's and a beocom 5 on a single beoline base and get the same issue as well. Whilst answering any of the phones, the other two will continue to ring for a second or two.

Sadly it's got to be a B&O issue not a BT problem. Before installing the Beocom 5's, we had 2 x BT digital cordless phones using the same setup. No issues with delayed ringing on the other phone with those BT phones.
