Ah... found it... it's set on multicall - is that the one it should be on?
I think multi call is found using BT phone and then settings then line settings
Entirely up to you.
Multi call means you can make/receive 2 calls simultaneously.
Ah... I see. I didn't even know you could do that. I might try switching it and see if by any chance it makes the whole darn thing work more consistently. Thanks for your assistance.
Worth a try, it is a bit of a double edged sword.
